MK-121型甲醇合成催化剂的升温还原

介绍了甲醇合成回路流程及MK-121型甲醇合成催化剂的升温还原情况。从出水量、耗氢情况来看,催化剂还原得非常彻底;另外,在催化剂还原过程中,循环量、甲醇合成塔进出口气体温度、顶部绝热层温度、进口H_2含量、系统压力等指标都非常平稳。实际运行情况证明,该催化剂具有较高的转化率、选择性、活性和稳定性。

Reduction by Heating of MK-121 Type Methanol Synthesis Catalyst

It is presented of methanol synthesis loop and conditions of reduction by heating of MK- 121 type methanol synthesis catalyst. On conditions of water yield and hydrogen consumption, the reduction of catalyst is completely. Besides, in the catalyst reduction process, the various key indices of circulating amount, inlet and outlet temperatures of synthesis tower, insulating layer temperature at top of synthesis tower, H2 content at inlet of synthesis tower and system pressure are very stable. Actual operation conditions show that the catalyst has higher conversion rate, selectivity, activity and stability.
