【摘要】:介绍了RSS-2催化剂在中国石油兰州石化公司航煤加氢装置上的应用情况,结果表明,以常减压装置常一线直馏煤油为原料,在进料量71.4t/h、反应器入口温度278.5℃、入口压力3.72MPa、空速3.72h~(-1)、氢油比181的工艺操作条件下,经加氢反应、分馏、脱除硫化氢后,精制航煤中硫质量分数由138μg/g降至3μg/g,脱硫率达到97.83%,碱性氮质量分数由2.71μg/g降至0.12μg/g,脱碱氮率达到95.57%,产品质量满足3号喷气燃料的质量标准;为满足低凝柴油的生产要求,在常一线直馏煤油中掺炼常二线,在常二线占混合原料质量分数从25%增加到50%时,混合原料中硫质量分数可降至20μg/g以下,满足国Ⅳ低凝柴油的调和要求,说明该催化剂具有良好的加氢脱硫、脱碱氮效果。
