Low temperature catalytic gasification in fluidized bed reactor for syngas production (original) (raw)

Abstract

The economic development in the world has faced mankind with two major energy challenges: the substitution of fossil fuels and the reduction of greenhouse gas emissions. Hydrogen has the potential to solve these challenges. A great effort is therefore made to develop new technologies of production, delivery, storage, conversion, and end-use of hydrogen. One of the promising ways for hydrogen production is biomass gasification. In this work, this process is studied experimentally in attempt to ameliorate its efficiency in term of hydrogen or syngas yield. Three liquid catalysts were used for that purpose. Analysis of the gas produced was performed and the results show that the catalysts improved the carbon monoxide yield through low temperature carbon dioxide gasification, whereas no remarkable improvement was found for hydrogen yield. Experiments at higher temperatures could reveal higher catalyst effect on the products of the process and on the hydrogen yield particularly.
