我厂1990年上中串低,1991年改全低变新工艺,除了1992年初新增部分催化剂外,大部分催化剂从1990年使用至今,已进入第五个年头,活性仍相当好,该产品系湖北省化学研究所研制生产的EB—4型低变催化剂。目前一变炉催化剂热点为370℃左右,出口CO5％～6％,二变炉催化剂热点210℃ In the middle of 1990, the plant was low in series. In 1991, the company changed the whole process to new low-transformation technology. Except for the addition of some catalysts in early 1992, most of the catalysts have been used for the fifth year since their use in 1990 and their activity is still quite good. Department of Chemistry, Hubei Province, developed and produced by the EB-4 type low-shift catalyst. At present, a hot spot for the converter catalyst is about 370 ℃, outlet CO5% ~ 6%, two-variable catalyst hot spot 210 ℃
