摘要
比较了由生物质衍生的3种气体:含N_2且未调节C/H比的气体(A)、不含N_2但未调节C/H的气体(B)、不含N_2且调节C/H的气体(C)催化合成甲醇的性能。在P=4MPa、r=260℃、SV=5280h^(-1)下,与气体(C)比,气体(A)和气体(B)所得甲醇产率分别下降47.2%和25.5%,甲醇浓度分别下降1.4%和1.6%。反应温度对含CO_2的气体(A)和(B)合成甲醇的性能有重要影响,在260℃时甲醇产率和浓度都达到最佳值。大量CO_2的存在导致甲醇浓度的下降,CO_2含量越高,所得甲醇的浓度越低。
The synthesis of methanol was carried out from three kinds of syngas derived from biomass: the syngas containing N2 and not adjusting C/H (A), the syngas without N2 and not asjusting C/H (B), the syngas without N2 and adjusting C/H (C). When P = 4MPa, T = 260%, SV = 5280h^-1, comparaed with (C), the methanol STY from (A) and (S) decreased 47.2% and 25.5% respectively, the methanol concentration from (A) and (B) decreased 1.4% and 1.6% respectively. Reaction temperature had important effect on methanol synthesis from (A) and (B), and both methanol STY and methanol concentration approached maximum at 260%. The existence of excess CO2 in syngas resulted in the decrease of methanol concentration. More CO2 in syngas, more greatly the methanol concentration decreased.
