摘　　要：山西梗阳新能源有限公司甲醇分公司焦炉煤气制SNG装置中,甲烷化反应使用的CNJ-6a型甲烷化催化剂在钝化过程中出现烧结现象,为此进行了烧结过程及钝化烧结原因分析,并就催化剂钝化过程从床层温度控制、循环量控制、压力控制,甲烷化反应器入口氧含量控制,催化剂装填质量控制等方面提出保护建议。In the coke oven gas to SNG plant in Methanol Branch of Shanxi Gengyang New Energy Co.,Ltd.,the CNJ-6a methanation catalyst used in the methanation reaction was sintered during the passivation process.For this reason,the sintering process and sintering causes were analyzed.Finally,protection suggestions were put forward for the catalyst passivation process from the aspects of bed temperature control,circulation volume control,pressure control,methanation reactor inlet oxygen content control,catalyst loading quality control,etc.
