摘　　要：开发了渣油加氢脱金属剂、脱硫剂和脱残碳剂等系列催化剂,在单剂性能理想的前提下,进行了各类型催化剂级配方案的优化探索。结果标明,在新的催化剂级配方案下,原料中的镍和钒重金属总脱除率≥90%、硫的脱除率≥90%、氮的脱除率≥50%、残碳的脱除率≥60%,达到了某炼厂400万t/a渣油固定床加氢装置的生产要求。A series of catalysts for residue hydrogenation are developed,including heavy metal removal catalyst,desulfurization catalyst and residual carbon removal catalyst.On the premise of ideal single-agent evaluation,the optimization and exploration experiments for various grading schemes are carried out.Total removal rates of nickel/vanadium,sulfur,nitrogen,and residual carbon in raw material exceed 90%,90%,50%and 60%,respectively,which meet the production requirements of a refinery's 4 million tons/year fixed-bed residue hydrogenation unit.
