鹤煤公司甲醇MK-121铜基催化剂还原总结

Summary of Methanol MK-121 Copper-based Catalyst Reduction

鹤壁煤电股份有限公司化工分公司甲醇设计产能为60万t/a,使用丹麦托普索低压甲醇合成工艺包,并采用了托普索推荐的MK-121铜基催化剂做为合成催化剂,氧化态催化剂的升温还原分为两个步骤:170℃前升温脱除物理水,170℃后升温还原脱除化学水。升温热源采用本单位自产4.2MPa中压过热蒸汽,所采用还原剂为99.9%的纯氢,该过程历时64h,升温脱水均匀,出水量与理论值相符,铜基催化剂还原效果良好,在后面的开车中得到了证明。

Hebi coal and electricity Co. , Ltd. , Chemical branch design production capacity of 600000 tons of methanol/year, using the top line low pressure methanol synthesis process, package, and used the MK - 121 recommended by top cable copper base catalyst for synthesis of catalyst, the oxidation catalyst is divided into two steps： physical water heat removal before 170 ℃, 170 ℃ after reduction removal of chemical water. Heating heat source in the units produced 4.2 Mpa medium pressure superheated steam, adopted by reducing agent is 99.9% pure hydrogen, this process is over 64 hours, uniform heating dehydration, water yield is consistent with the theoretical value, copper base catalyst reduction effect is good, in the behind of driving.
