摘要/Abstract

摘要： 以可燃性气体为目的产物,在450~600 ℃低温条件下对木屑进行微波催化热解。考察了热解温度、催化剂种类以及催化剂用量对微波热解可燃气产量和热值的影响,并分析热解过程中各气体组分的变化趋势。结果表明:催化剂的加入可有效提高气体产率,不同催化剂对气体产率的影响顺序为:K₂CO₃ > NaOH > Na₂CO₃ > MgO > CaO > NaH₂PO₄ > Na₂HPO₄。在热解温度550 ℃、K₂CO₃用量(以木屑质量计)20%的条件下得到高产量的中热值可燃性气体,气体产率为62.65%,低位热值14.05 MJ/m³;且K₂CO₃作为催化剂时可得到较高的H/C的气体。

Abstract: The production of combustible gas from sawdust using microwave pyrolysis at a low-temperature of 450-600 ℃ was carried out. Variation of the gases composition was analyzed during the pyrolysis process. The effects of pyrolysis temperature, different kinds of catalysts, and different amounts of K₂CO₃ on the changes of components in combustible gas were studied. The results showed that under the conditions of pyrolysis temperature 550 ℃ and 20% amounts of K₂CO₃, the maximum yield of combustible gas was 62.65% with low heating value (LHV) of 14.05 MJ/m³. The combustible gas with high H/C ratio could be obtained under the catalysis of K₂CO₃.
