我公司是以煤焦为原料,年产8万t合成氨、2万t联醇的中氮厂,采用常压栲胶脱硫,2.1MPa中变串低变,热钾碱法脱碳、联醇、铜洗精炼流程。1999年2月份中变新催化剂在运行5个月后,阻力就大幅度升高,严重制约公司的正常生产,于是对催化剂进行蒸汽反吹,物理爆破,添加部分旧催化剂等措施 My company is based on coal as raw material, with an annual output of 80,000 tons of ammonia, 20,000 tons of Lianzhong nitrogen plant, the pressure Jie 栲 plastic desulfurization, 2.1MPa variable string low temperature, decalcified by hot potash, alcohol , Copper wash refining process. In February 1999, the new catalyst became more active after 5 months of operation, causing a substantial increase in resistance and seriously restricting the normal production of the Company. Steam catalysis, physical blasting and addition of some old catalysts were carried out on the catalyst
