JT型炼油厂干气加氢精制催化剂的开发及应用

摘要

Development of hydrofining catalyst for refinery dry gas and its application in hydrogen production as well as the revamping of feedstoc k route for large or middle scale synthetic ammonia unit were introduced.The JT -1G coking gas hydrofining catalyst and the JT-4 isothermal hydrofining cataly st are characterized by convenience,flexibility and steady.Matching with zinc ox ide desulfurizer,the olefin volumetric fractions of coking dry gas and mixed dry gas of coking and catalytic cracking can be reduced from 4%～8% and 16%～20% to bellow 0.5%,while organic sulfur from 200 μg/g to bellow 0.5 μg/g,respectivel y.Considerable economic benefits were obtained.%介绍了炼油厂干气加氢精制催化剂的开发及其在炼油厂制氢、大中型合成氨原料路线改造工程中的应用概况。JT-1G焦化干气加氢精制催化剂和JT-4等温加氢精制催化剂及其工艺使用方便、灵活、稳定，在锦西炼油化工总厂和齐鲁石油化工公司第一化肥厂应用，与氧化锌脱硫剂串联，可使炼厂焦化干气和焦化、催化混合干气的烯烃体积分数分别由4%～8%和16%～20%降至0.5%以下，使有机硫含量由200 μg/g降至总硫0.5 μg/g以下，取得了可观的经济效益。
