Research Progress of Hydrogen-rich Gas Production from Biomass by Thermo-chemical Process

Hydrogen is a kind of clean secondary energy and biomass can be used as an important source of hydrogen. Biomass thermo-chemical conversion technology of hydrogen-rich gas production is an important way for the development and utilization of biomass energy. Gasification is one of the most mature thermo-chemical technologies,and is also considered one of the most promising route to produce hydrogen-rich gas. Starting from the characteristics of thermo-chemical conversion, the methods of catalytic gasification and supercritical water gasification were compared and analysed. The current domestic and home research progress and problems were reviewed. It also looked forward the prospects of thermo-chemical conversion technologies in China,at the same time research directions and development trends were suggested.
