摘　　要：为了开发低温液相甲醇合成新工艺,使用CuCr/CH3ONa催化体系,在直径40 mm的鼓泡浆液反应器中考察了低温甲醇合成的反应性能. 鼓泡浆液反应器使用的浆液由铜铬催化剂、甲醇钠溶液、乳化剂OP-10和液相介质二甲苯组成.实验结果表明在90 ℃～110 ℃、4.8 MPa和操作气速0.2 cm/s下,前9 h的CO平均转化率达到78%.甲醇是反应的主要产物.与搅拌釜中的实验结果比较,鼓泡浆液反应器的反应效率为搅拌釜的80%.这是由于甲醇钠的消耗和乳化剂的负效应所致.实验结果示范了鼓泡浆态反应器中低温甲醇合成的可行性.In order to develop a new process of low-temperatutre methanol synthesis, reaction performance of the low-temperature methanol synthesis catalyst CuCr/CH3 ONa was examined in the bubble column slurry reactor （BCSR） of 40 mm in diameter and 4 500 mm height. The slurry was composed of the required amounts of sodium methoxide solution, CuCr catalyst and emulsifier OP-10, as well as the balanced liquid xylene medium. The results showed that the average conversion of CO was 78% in 90 ℃ ～ 110 ℃, 4.8 MPa and operation gas velocity 0.2 cm/s during first 9 h of operation test. Methanol was main product from BCSR. Compared with the results of the test in the autoclave, efficiency of BCSR is about 80% of the autoclave reactor＇s. This is probably due to the consumption of CH3ONa and the negative effect of emulsifier OP-10. Results demonstrated the feasibility of the application of BCSR in low temperature methanol synthesis in slurry.
