        該文以甲苯為焦油模型化合物,利用生物質焦炭誘導其轉化合成氣,探討加熱方式和通入CO2對甲苯轉化的影響。結果表明:同等工況下,微波加熱(microwave heating,MH)下甲苯轉化率高于常規加熱(electrical heating,EH),甲苯轉化率最大差值為15.58%。通入CO2可促進甲苯轉化,MH和EH下分別在CO2流量為80和40 mL/min達到最高轉化率93.73%和82.13%。引入CO2可調控甲苯定向制備合成氣,且對生物質焦炭造成碳損耗。損耗碳可轉化合成氣,且CO2通入量越高,其貢獻越大。MH下合成氣最大產率為173.66 mL/min,為裂解反應的5.68倍。甲苯裂解率持續降至49.0%,之后趨于穩定。甲苯重整轉化率維持較高水平,140 min后開始減弱,同時合成氣收率平緩降低。該文研究結果對高效利用焦油和減排CO2有借鑒意義。...

      • 以菊芋粉為原料同步糖化發酵生產燃料乙醇

        利用粟酒裂殖酵母(Schizosaccharomyces pombe)能發酵菊芋未水解糖液高產乙醇的特點提出了以菊芋粉為原料,同步糖化發酵生產燃料乙醇的新工藝.在搖瓶中考察了原料預處理方法、原料濃度和初始pH值對乙醇發酵的影響,進而在5 L發酵罐中考察了未調控pH值和恒定pH值與通氣情況對乙醇發酵的影響.結果表明:該菌株最適pH值為4.0;100目篩分的菊芋粉發酵效果良好,115℃滅菌處理優于121℃,在此條件下,菊芋粉濃度200 g/L時,乙醇產量達到 66.58 g/L,理論轉化率為85.88%;發酵液pH值下降對乙醇發酵沒有影響,通入適量氧氣會導致乙醇產量的下降,這表明粟酒裂殖酵母進行乙醇發酵時不需要供氧;通入氮氣保持厭氧環境不能顯著提高乙醇產量,不通氣進行乙醇發酵也達到高的轉化率,因此在工業生產中,不必保持厭氧發酵環境.在此基礎上,對菊芋粉補料發酵進行了試驗,補料至菊芋粉終濃度為300 g/L,發酵終點乙醇濃度為94.81 g/L,理論轉化率為81.54%.這些研究工作,為以菊芋為原料的燃料乙醇工業化生產提供技術依據....

      • Chemical-looping gasification of biomass in a 10k Wth interconnected fluidized bed reactor using Fe2

        The aim of this research is to design and operate a 10 kW hot chemical-looping gasification ( CLG) unit using Fe2 O3/Al2 O3 as an oxygen carrier and saw dust as a fuel. The effect of the operation temperature on gas composition in the air reactor and the fuel reactor, and the carbon conversion of biomass to CO2 and CO in the fuel reactor have been experimentally studied. A total 60 h run has been obtained with the same batch of oxygen carrier of iron oxide supported with alumina. The results show that CO and H2 concentrations are increased with increasing temperature in the fuel reactor. It is also found that with increasing fuel reactor temperature, both the amount of residual char in the fuel reactor and CO2 concentration of the exit gas from the air reactor are degreased. Carbon conversion rate and gasification efficiency are increased by increasing temperature and H2 production at 870 ℃reaches the highest rate. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and BET-surface area tests have been used to characterize fresh and reacted oxygen carrier particles. The results display that the oxygen carrier activity is not declined and the specific surface area of the oxygen carrier particles is not decreased significantly....

      • Performance evaluation of a diesel engine by using producer gas from some under-utilized biomass on

        Producer gas through gasification of biomass can be used as an alternate fuel in rural areas due to high potential of biomass resomces in India.Experiments were conducted to study the performance of a diesel engine (four stroke,single cylinder,5.25 kW) with respect to its thermal efficiency,specific fuel consumption and diesel substitution by use of diesel alone and producer gas-cum-diesel (dual fuel mode).Three types of biomass,i.e.wood chips,pigeon pea stalks and com cobs were used for generation of producer gas.A producer gas system consisting of a downdraft gasifier,a cooling curm cleaning unit,a filtering unit and a gas air mixing device was designed,fabricated and used to power a 5.25 kW diesel engine on dual fuel mode.Performance of the engine was reported by keeping biomass moisture contents as 8%,12%,16%,and 21%,engine speed as 1 600 r/rmin and with variable engine loads.The average value of thermal efficiency on dual fuel mode was found slightly lower than that of diesel mode.The specific diesel consumption was found to be 60%-64% less in dual fuel mode than that in diesel mode for the same amount of energy output.The average diesel substitution of 74% was observed with wood chips followed by corn cobs (78%) and pigeon pea stalks (82%).Based on the performance studied,the producer gas may be used as a substitute or as supplementary fuel for diesel conservation,particularly for stationary engines in agricultural operations in the farm....

      • Fast Pyrolysis of Biomass in a Spout-fluidized Bed Reactor--Analysis of Composition and Combustion C

        In order to gain insight into the fast pyrolysis mechanism of biomass and the relationship between bio-oil composition and pyrolysis reaction conditions, to assess the possibility for the raw bio-oil to be used as fuel, and to evaluate the concept of spout-fluidized bed reactor as the reactor for fast pyrolysis of biomass to prepare fuel oil, the composition and combustion characteristics of bio-oil prepared in a spout-fluidized bed reactor with a designed maximum capacity 5 kg/h of sawdust as feeding material, were investigated by GC-MS and thermogravimetry. 14 aromatic series chemicals were identified. The thermogravimetric analysis indicated that the bio-oil was liable to combustion, the combustion temperature increased with the heating rate, and only minute ash was generated when it burned. The kinetics of the combustion reaction was studied and the kinetic parameters were calculated by both Ozawa-Flynn-Wall and Popsecu methods. The results agree well with each other. The most probable combustion mechanism functions determined by Popescu method are f(α)=k(1-α)2(400~406 ℃), f(α)=1/2k(1-α)3 (406~416 ℃) and f( α)=2k(1-α)3/2 (416~430 ℃) respectively....

      • RESEARCH ON REUSE OF PAPERMAKING LIGNIN-CONVERSION OF LIGNIN TO BTX BY CATALYTIC PYROLYSIS IN A POWD

        Experiments on the catalytic pyrolysis of the papermaking lignin were conduced by using a new type of powder-particle fluidized bed to improve the yield of the light aromatic hydrocarbon, i.e. benzene,toluene, xylene and naphthalene (BTXN), in which the primary decomposition and secondary catalytic reaction occur simultaneously at ambient pressure.The effect of catalyst species, fluidizing gases and pyrolysis temperature on the yield of the BTXN were investigated. The content of sulfur is high in the papermaking lignin, and the volatile matter is effected by the temperature. In the case of the inert media silica sand, the yield and the distribution of the pyrolysis products were almost unchanged under the different kind of atmosphere. In the case of the catalyst CoMo-B with hydrogen atmosphere, the intermediate BTXN yield reached 2.52wt%, dry, 3.3 times as much as that in the case of silica sand.Therefore, in order to obtain valuable BTXN as an intermediate in the pyrolysis as much as possible, it is extremely important to select high sulfur resistance and hydrogenization activity catalyst....

      • Non-isothermal Kinetics of Pyrolysis of Three Kinds of Fresh Biomass

        The pyrolysis kinetics of three different kinds of fresh biomass (grass: triple A, wheat straw, com straw) in nitrogen flow were studied by thermogravimetric analysis at five different heating rates. The kinetic parameters of the pyrolysis process were calculated using the method of Ozawa-Flynn-Wall and the mechanism of reactions were investigated using the method of Popescu. It was found that the values of activation energy varied in different temperature ranges. The pyrolysis processes are well described by the models of Zhuravlev (Zh) and valid for diffusion-controlled between 200℃ and 280℃, by Ginstling-Brounshtein (G-B), valid for diffusion-control between 280℃ and 310℃, for first-order chemical reaction between 310℃ and 350℃, by Zhuravlev (Zh) valid for diffusion-control between 350℃ and 430℃ and by the one-way transport model when temperatures are over 430℃....

      • Biomass Catalytic Pyrolysis with Ni Based Catalyst to Produce Hydrogen Rich Gas

        Hydrogen rich gas was produced using rice husk as biomass material on the continuous biomass pyrolysis apparatus which consisted of continuous pyrolysis reactor and secondary catalytic cracking reactor. Ni based catalysts of different Ni/Al mass ratio and calcined temperature were prepared by impregnating method. The catalysts were characterized by X-ray diffraction (XRD),scan electron microscope (SEM) and FT-IR Spectrometer (FT-IR). Ni based catalyst showed good selectivity for H2 production from biomass. Catalysts prepared under different conditions had little influence on the yields of three states products when used at the same cracking temperature. Ni/Al mass ratio played an important role in products selectivity. However, the content of NiO increased further when Ni/Al mass ratio values reached 0.7 : 10, and the yield of H2 slightly increased. Hydrogen yield was greatly impacted by calcined temperature. Catalyst calcined at 550"C performed best. When the catalyst was calcined at high temperature, NiO in the catalyst transformed into NiAl2O4, and the acid site also changed, which caused the deactivation of the catalyst. The hydrogen yield increased with the cracking temperature. The highest stable yield of hydrogen was about 30% without increasing with the cracking temperature....

      • TG-FTIR Study on Corn Straw Pyrolysis-influence of Minerals

        In order to study the effect of minerals on biomass pyrolysis, experiments on pyrolysis of corn straw with different pretreatment methods were performed by using a thermogravimetric analyzer(TGA) coupled with a Fourier transform infrared(FTIR) spectrometer. The pretreatment methods included water washing and acid washing. The experimental results show that acid washing can remove almost all K+ and 78% of Ca2+, while water washing only removes most of K+. The existence of K+ and Ca2+ obviously favors the formation of compounds containing carbonyl groups and CO2, but it will decrease the yields of compounds containing C-O-C groups. However, the formation of H2O, CO and CH4 are slightly affected by the removal of inorganic ions. With regard to the structure of the metal ions-adsorbed cellulose characterized by IR analysis, it can be considered that there is an "ion force" between metal ions and cellulosic biomass. The results of thermal kinetic analysis show that this force can make the reaction activation energy of the biomass pyrolysis decrease. A new mechanism is proposed for explaining the effect of inorganic ions on cellulose pyrolysis....

      • Kinetics study on biomass pyrolysis for fuel gas production

        Kinetic knowledge is of great importance in achieving good control of the pyrolysis and gasification process and optimising system design. An overall kinetic pyrolysis scheme is therefore addressed here. The kinetic modelling incorporates the following basic steps: the degradation of the virgin biomass materials into primary products (tar, gas and semi-char), the decomposition of primary tar into secondary products and the continuous interaction between primary gas and char. The last step is disregarded completely by models in the literature. Analysis and comparison of predicted results from different kinetic schemes and experimental data on our fixed bed pyrolyser yielded very positive evidence to support our kinetic scheme....

      • Emissions of SO2,NO and N2O in a circulating fluidized bed combustor during co-firing coal and bioma

        This paper presents the experimental investigations of the emissions of SO2, NO and N2O in a bench scale circulating fluidized bed combustor for coal combustion and co-firing coal and biomass. The thermal capacity of the combustor is 30 kW. The setup is electrically heated during startup. The influence of the excess air, the degree of the air staging, the biomass share and the feeding position of the fuels on the emissions of SO2, NO and N2O are studied. The results show that an increase in the biomass shares results in an increase of the CO concentration in the flue gas, probably due to the high volatile content of the biomass. In co-firing, the emission of SO2 increased with the increasing biomass share slightly however, non-linear increase relationship between SO2 emission and fuel sulfur content is observed. Air staging decreases the NO emission significantly without raising the SO2 level. Though change the fuel feeding position from riser to downer results in a decrease in the NO emission level, no obvious change is observed for the SO2 level. Taking the coal feeding position R as a reference, the relative NO emission can significantly decrease during co-firing coal and biomass when feeding fuel at position D and keeping the first stage stoichiometry greater than 0.95. The possible mechanisms of the sulfur and nitrogen chemistry at these conditions are discussed and the ways of simultaneous reduction of SO2, NO and N2O are proposed....
