Study On Comprehensive Evaluation Of Hydrogen Production Technology From Biomass

The rule of hydrogen production from biomass such as walnut, peanut,sawdust and digested municipal sewage sludge via pyrolysis with catalysts was investigated, and the concept of comprehensive evaluation of hydrogen production techonology for biomass(CEHPTB) was put forward based on the knowledge of the process of hydrogen production from biomass via pyrolysis with catalyst. The comprehensive evaluation index system of hydrogen production technology from biomass(HPTB) was extracted and established by analyzing the interaction between hydrogen production technology from biomass and the system of energy-economy-environment with the method of systemic analysis. The model for fuzzy comprehensive evaluation of hydrogen production technology from biomass was constructed, and has been used to analyze the comprehensive evaluation of hydrogen production technology from biomass. Four typical HPTBs have been compared including hydrogen generation technology from biomass by anaerobic fermentation(HGTBAF), hydrogen generation technology from biomass by gasification(HGTBG), hydrogen generation technology from biomass by pyrolysis(HGTBP) and hydrogen generation technology from biomass by supercritical water gasification(HGTBSWG). The result showes that, the four types of hydrogen production technology form biomass have the turn like that HGTBG> HGTBP> HGTBSWG> HGTBAF under current conditions.
