Biomass gasification is an important method to obtain renewable hydrogen. However, this technology still stagnates in a laboratory scale because of its high-energy consumption. In order to get maximum hydrogen yield and decrease energy consumption, this study applies a self-heated downdraft...

Nanometer magnetic solid base catalysts were prepared by loading CaO on Fe3O4 with Na2CO3 and NaOH as precipitator, respectively. The optimum conditions for preparation of this catalyst were investigated. The influence of the proportion of Ca2+ to Fe3O4 on the catalytic performance has been...

In order to crack the tar from biomass pyrolysis, five cordierite-supported monolithic catalysts with different Ni/Co ratio were prepared by vacuum wetness impregnation. All catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), temperature-programmed...

Direct conversion of biomass-derived syngas (bio-syngas) to dimethyl ether (DME) at pilot-scale (100t/a) was carried out via pyrolysis/gasification of corncob. The yield rate of raw bio-syngas was 40–45Nm3/h with less than 20mg/Nm3 of tar content when the feedrate of dried corncob was...

A kind of solid catalyst of Fe(Ⅱ)–Zn double-metal cyanide (DMC) complexes was prepared through co-reaction of potassium ferrocyanide, zinc chloride and complexing agent of tert-butanol. This catalyst was characterized by using several techniques such as XRD, TG/FT-IR, EA, BET and SEM. And it...

In this study, a pilot scale of 100t/year biodiesel production system, mainly consisting of a fixed-bed and a down-stream plug-flow reactors, was setup to test different feedstock oils, especially a kind of high-acidified oil, trap grease, for their feasibility as biodiesel feedstock in China....

Detailed review of existing models resulted in the development of a new mathematical model to study biomass gasification in a circulating fluidized bed. Hydrodynamics as well as chemical reaction kinetics were considered to predict the overall performance of a biomass gasification process. The...

The developed 1-dimensional biomass gasification mathematical model [1] was validated using the experimental results obtained from a circulating fluidized bed biomass gasifier. The reactor was operated on rice husk at various equivalence ratios (ER), fluidization velocities and biomass feed...
