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。 The methanol catalyst (MeLi) was mechanically mixed with HZSM-5 molecular sieve to prepare LPG synthesis catalyst. Synthetic LPG studies were carried out after decarbonization of biomass gas by fluidized bed. The results showed that the optimal reaction temperature for LPG synthesis was 325 ℃ and the optimal reaction pressure range was 2.1 ~ 3.6 MPa. Under the conditions of 325 ℃, 2.1MPa and 2000h-1, the single-pass conversion of CO reached 83.25%, and the target product C3 + C4 accounted for 83.17% of the total organic products. The catalysts were characterized by XRD before and after the reaction, and the catalyst activity center was Cu (111). By calculation, per ton of dry woody biomass can produce 0.0786tLPG and cogeneration power of 607kWh.
