Research on the preparation of Fischer-Tropsch synthesis gas by biomass carbonization pyrolysis gas catalytic reforming

Biomass pyrolysis gas is a kind of high calorific value combustible gas, which has important development and utilization value. However, due to its complex components, multi-tar oil, CO2, CH4 and other components have tremendous hazard to pyrolysis gasification process and related equipment. and the viscous liquid formed by condensation is likely to cause blockage of the pipeline, and the carbon black generated by direct combustion will cause environmental pollution, all of which constitutes a major factor restricting the further development and utilization of pyrolysis gas. This paper analyzes the feasibility of pyrolysis gas catalytic reforming to Fischer-Tropsch synthesis gas. It introduces respectively the research status of continuous and segmented pyrolysis-catalytic reforming equipment, nickel-based, calcium-based, iron-based, alkali-based, carbon and other catalysts as well as pyrolysis gas separation and purification technology, analyzes the existing problems in current research in terms of non-uniformity of catalytic reforming equipment, lack of relevant industry standards, different catalysts and catalytic reforming effect as well as unclear mechanism of catalyst additives, proposes the future research direction such as the application of segmented pyrolysis-catalytic reforming equipment and using biochar as catalytic reforming catalyst, opens up a new way of development and utilization of biomass carbonization pyrolysis gas. © 2019, Chemical Industry Press Co., Ltd..
