摘要
用新研制的具有高抗结炭性能的负载型镍催化剂ＳＹＭ－１，模拟工业用变温固定床，进行了ＣＨ４－Ｈ２Ｏ－ＣＯ２体系制取合成甲醇用合成气的实验。结果表明，该催化剂对ＣＨ４－Ｈ２Ｏ－ＣＯ２反应具有良好的催化活性，能够制得工业合成甲醇用的合成气。甲烷的转化率和产物ＣＯ含量随温度升高而增加，随压力增大而下降。其较佳的反应条件为：反应温度９００℃；压力０．１～０．７ＭＰａ，甲烷空速５００～１５００ｈ－１；原料配比ＣＨ４：Ｈ２Ｏ：ＣＯ２＝１：（１．１～１．５）：０．３。
n experimental preparation of feedstock gas for methanol synthesis by methane reforming with steam and CO2 has been investigated with the newly prepared nickel-based catalyst of high anti-carbon deposit in a simulated industrial temperature variable fixed bed. The results shown that this catalyst has excellent activity and the qualified syngas for methanol production in inclustry call be manufactured. The conversion of CH4 and the content of product CO increase with temperature and decrease with pressure rising. The optimum reaction conditions are as below: t=900℃; P=0. 1～0. 7MPa; SV of CH4=500～1500h-1; CH4:H2O: CO2=1:(1.1～1. 5):0.3.
