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 %～ 2 0 %降至 0 .5 %以下 ,使有机硫含量由 2 0 0 μg/g降至总硫 0 .5 μg/g以下 ,取得了可观的经济效益
The development of refinery dry gas hydrotreating catalyst and its application in hydrogenation project and large and medium-sized synthetic ammonia raw material reformation project are introduced. JT 1G coking dry gas hydrotreating catalyst and JT 4 isothermal hydrotreating catalyst and its process easy to use, flexible and stable, in the Jinxi Petrochemical Plant and the first chemical fertilizer plant Qilu Petrochemical Company, and zinc oxide desulfurizer In series, the volume fraction of olefins in refinery coking dry gas, coking and catalytic mixed dry gas can be reduced from 4% -8% and 16% ~ 20% to below 0 5% respectively, μg / g down to less than 0.5 μg / g total sulfur has achieved considerable economic benefits
