摘要
以流化床为反应器 ,探讨了一些主要参数如 :反应器温度 ,水蒸气 ,当量比ER以及催化剂对气体成分、氢产率和潜在氢产率的影响。实验所用催化剂为白云石和镍基催化剂。在实验条件范围内 ,氢产率为 2 2— 83g/kg生物质 (湿基 ) ,潜在氢产率为 115— 2 2 3g/kg生物质 (湿基 )。结果表明 ,较高的反应器温度 ,适当的水蒸气添加量可以有效提高氢的产出 ;白云石和镍基催化剂可使产品气中的氢含量提高 10 %以上。
Parametric experiments were performed in a fluidized bed to determine the effects of reaction temperature, steam, equivalence ratio (ER) and catalysts on gas composition, hydrogen and potential hydrogen yield. The catalysts used were dolomites and nickel based catalysts and were located in gasifier and a downstream fixed reactor, respectively. Of the conditions tested, hydrogen yield ranges between 22 and 83 g per kg of biomass (wet basis) and hydrogen yield potential ranges between 115 and 223 g per kg of biomass (wet basis). The experimental results prove that higher reaction temperature, proper steam quantity and ER will contribute to more hydrogen production. Hydrogen concentration of gaseous product can be increased over 10% through the use of dolomite and nickel based catalysts.
