Abstract: The behavior of methanol synthesis from biomass syngas, industrial syngas, reformed biomass syngas and hydrogen added biomass syngas was studied. The results show that the order of the yield of methanol is industrial syngas>reformed biomass-gas> hydrogen added biomass-gas>biomass-gas, and the lower yield of methanol from biomass syngas mainly results from higher concentration of carbon dioxide. (H2-CO2)/(CO+CO2) ratio has no obvious influence on the selectivity of methanol in liquid products when the (H2-CO2)/(CO+CO2) ratio is between 1.5 and 2. High concentration of carbon dioxide results in reduction of selectivity of methanol in liquid products.
Key words: biomass syngas, methanol synthesis, CO2-rich syngas
摘要: 对生物质气、工业合成气、重整后生物质气及配氢后生物质气4种合成气进行了合成甲醇的研究. 发现甲醇产率顺序为工业合成气>重整生物质气>配氢生物质气>生物质气,生物质气合成甲醇产率较低主要是因为其为富CO2体系. 实验同时发现(H2-CO2)/(CO+CO2)比值在1.5~2之间时,(H2-CO2)/(CO+CO2)比值对液相产物中甲醇选择性没有明显影响. 液相产物中甲醇选择性随CO2含量上升而下降.
