研究了Ni-Cu(催化剂的比表面积、原料气含O_2量等对乙醇羰化合成丙酸和丙酸乙醇的影响。在常压和300℃下,Cu_(2+)为2.2％和CO/C_2H_5OH=2.8(摩尔)时,丙酸和丙酸乙酯收率最高。对Cu_(2+)在催化剂中的作用以及催化剂的稳定性进行了讨论。
The effects of Ni-Cu on the specific surface area of catalyst, O 2 content of feed gas, et al. Were studied. The results showed that under atmospheric pressure and 300 ℃, the Cu 2+ content was 2.2% and CO 2 / The yield of propionic acid and ethyl propionate reached the highest when C_2H_5OH = 2.8 (mol), the effect of Cu_ (2+) in the catalyst and the stability of the catalyst were discussed.
