生物质气化重整催化合成液化石油气

INDIRECT SYNTHESIS OF LPG FROM REFORMING BIOMASS SYNGAS

以甲醇催化剂(MeLi)与HZSM-5型分子筛机械混合,制备LPG合成催化剂。通过对流化床制备的生物质气重整脱碳后进行合成LPG研究。结果表明,LPG合成最佳反应温度为325℃,最佳反应压力范围为2.1～3.6MPa。在325℃,2.1MPa,2000h-1条件下,CO单程转化率达83.25%,目标产物C3+C4占有机产物质量含量已达83.17%。通过XRD对催化剂反应前后进行表征,催化剂活性中心为Cu(111)。通过计算,每吨干基木质生物质可产0.0786tLPG和联产电力607kWh。

Synthesis of liquefied petroleum gas （LPG） from reforming of biomass syngas using hybrid catalyst consisting of methanol synthesis catalyst （MeLi） and HZSM-5 zeolite was investigated. The results show that the best reaction temperature of bifunctional catalyst is 325℃ and the best range of reaction pressure is 2.1-3.6MPa, and the CO conversion achieved 83.25% at 325℃, 2.1MPa, 2000h-1. The weight percentage content of target products achieved 83.17% in organic products. Cu（ 111） was assumed to be the active phase for DME synthesis, confirmed by X-ray diffraction （XRD） characterization.
