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...

Effect of iron promoter on the microstructures of CuMnZnO catalysts was investigated by N2 physical adsorption (BET), X-ray diffraction (XRD), and temperature-programmed reduction of hydrogen (H2-TPR). Higher alcohols synthesis (HAS) was performed in a fixed bed reactor. The characterization...

Impacts of H2/CO ratios on both the bulky and surface compositions of an iron–manganese based catalyst were investigated by XRD, MES, N2-physisorption, XPS and LRS. Fischer–Tropsch (F–T) synthesis performances were studied in a slurry-phase continuously stirred tank reactor. The...

The effect of Ni/Mg mole ratio of Ni–MgO/γ-Al2O3 cordierite monolithic catalysts on dry reforming of model biomass fuel gas(H2/CO/C2H4/CH4/CO2/N2=16.0/12.1/2.5/15.1/22.0/32.3, vol.%) was investigated in a lab-scale stainless steel tubular reactor. The results showed that CH4 and CO2...

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...

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...

Using a circulating fluidized bed (CFB) as the main reactor, an integrated process development unit was operated aiming at the pyrolysis of waste tires. The main chemical processes in the CFB can be divided into two zones corresponding to pyrolysis and secondary reactions. The pyrolysis of tire...
