摘要
在液相介质为二甲苯、甲醇或液体石蜡，温度１００～１４０℃、压力３．５～４．７ＭＰａ条件下，使用Ｈ２／ＣＯ＝２的合成气，在１Ｌ搅拌釜内考察了自制的ＣｕＣｒ／ＣＨ３ＯＮａ催化体系的浆态相低温甲醇合成的反应性能。结果表明液相介质以二甲苯为佳，ＣＯ转化率随压力而升高，温度以１２０℃为宜。４４ｈ的连续运转表明以ＣＯ转化率为代表的该催化体系的反应性能基本稳定。
Reaction performance of catalysis system composed of CuCr/CH 3ONa prepared in our laboratory for the low temperature methanol synthesis in slurry phase was examined The reaction conditions were as follows: temperature, 100～140℃; pressure, 3 54 7 MPa; syngas ratio (H 2/CO) 2/1; and xylene, methanol and liquid paraffin as liquid medium The results show that the optimum reaction conditions are 120℃ and 4 7MPa, and xylene is a better liquid medium CO conversion increases with increasing operation pressure Reaction performance of catalysis system represented by CO conversion was essencially stable during the duration test of 44 hours on stream
