Two-Stage Dry Reforming Process for Biomass Gasification: Product Characteristics and Energy Analysis

The utilization of biomass can not only alleviate the energy crisis but also reduce pollution fossil fuels to environment. Biomass gasification is one main methods, which effectively convert into high-value and wide-use gas. However, this process inevitably produces by-product tar, affects yield syngas. In order solve problem, a two-stage combining pyrolysis CO2 catalytic reforming proposed in paper, used prepare high calorific value syngas rich H2 CO tar while realizing resource CO2. effects temperature CO2/C ratio on gas were investigated by device, system consumption was analyzed. With increase temperature, increased, increased first then decreased. Increasing within proper range beneficial formation When 900 °C 1, with obtained, 2.75 MJ/kg obtained. At time, reached maximums, 0.46 Nm3/kg 0.28 Nm3/kg, respectively. Under these conditions, total 0.68 MJ/kg, slightly more than 0, does require too much external heat.
