Hydrogen Production Using Crude Bio-oil And Biomass Char By Catalytic And Electrochemical Catalytic Reforming

Biomass is a renewable and clean, exist widely energy resource, and Its price is cheap. Meanwhile, hydrogen is a fuel with high added value. So, biomass gasification becomes a hot spot in recent years. However, there are several problems still existing prevent bio-energy from commercializing. A lot of technical problems still need to be studied. Such as improving absolute hydrogen yield ect. Human need to large-scale utilize biomass. The main aim of this work is to efficiently produce hydrogen from the crude bio-oil and biomass char in the pyrolysis proportion of biomass over commercial catalyst in the dual fixed beds. An efficient and promising reforming approach for producing hydrogen from crude bio-oil and biomass char was proposed and investigated. (1) producing hydrogen from crude bio-oil (2) producing hydrogen from biomass char (3) producing hydrogen from crude bio-oil and biomass char. The influence of temperature and current on absolute hydrogen yield, carbon conversion and distribution of main product gases were reseached. The following were the results:1. The influence of temperatureThe absolute H2 yield and carbon conversion increased with the increasing reforming temperature. And the H2 and CO content increased with the increasing reforming temperature. At 800℃and 0A, the absolute H2 yield of three experiments were respectively 68.5g/kg,43.06 g/kg,102.67 g/kg; the carbon conversion of three experiments were respectively 80.5%,88.85%,82.0%.2 The influence of currentThe absolute H2 yield and carbon conversion increased with the increasing current at the same temperature. And the H2 and CO content increased with the increasing current. At 800℃and 3A, the absolute H2 yield of three experiments were respectively 72.9g/kg,45.7g/kg,110.9g/kg; the carbon conversion of three experiments were respectively 84.2%,94.4%,88.3%.3 The reasons The reactions are endothermic reaction, and the increasing temperature would increase the reaction rate. So, the temperature and current will affect the reactions.
