Gasification Process

The interest in the thermochemical conversion of biomass for producer gas production since last decade has increased because of the growing attention to the application of sustainable energy resources. Application of biomass resources is a valid alternative to fossil fuels as it is a renewable energy source. The valuable gaseous product obtained through thermochemical conversion of organic material is syngas, whereas the solid product obtained is char. This review deals with the state of the art of biomass gasification technologies and the quality of syngas gathered through the application of different gasifiers along with the effect of different operating parameters on the quality of producer gas. Main steps in gasification process including drying, oxidation, pyrolysis and reduction effects on syngas production and quality are presented in this review. An overview of various types of gasifiers used in lignocellulosic biomass gasification processes, fixed bed and fluidized bed and entrained flow gasifiers are discussed. The effects of various process parameters such as particle size, steam and biomass ratio, equivalence ratio, effects of temperature, pressure and gasifying agents are discussed. Depending on the priorities of several researchers, the optimum value of different anticipated productivities in the gasification process comprising better quality syngas production improved lower heating value, higher syngas production, improved cold gas efficiency, carbon conversion efficiency, production of char and tar have been reviewed.

Syngas Production

The co-gasification of wheat straw and wet sewage sludge for hydrogen-rich gas production was investigated in a fixed bed reactor with corn stalk char (CSC)-supported catalysts. The Ni/CSC, Ni-Fe/CSC, and Ni-Fe-La/CSC catalysts were characterized via ultimate analysis, X-ray fluorescence, thermogravimetric, X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, Brunauer-Emmett-Teller, and Fourier transform infrared spectroscopy analyses. A series of experiments were performed to explore the effects of reactor temperature, catalyst type, moisture content of wet sludge, and catalyst recycling performance on the composition and yield of gasification gases. The experiments demonstrated that the nickel-iron alloy (Fe0.64Ni0.36) was detected in the Ni-Fe-La/CSC catalyst, and the Ni-Fe-La/CSC catalyst showed much higher hydrogen production compared with the Ni/CSC and Ni-Fe/CSC catalysts. Furthermore, La2O3 effectively maintained the catalytic performance of the catalyst by relieving carbon deposition. Compared with non-catalyst biomass gasification, H2 yield increased from 3.80 mol/kg to 11.96 mol/kg using Ni-Fe-La/CSC catalyst at 600 °C. The newly developed tri-metallic Ni-Fe-La/CSC catalyst exhibited high catalytic activity for biomass gasification at low temperature.
