为加工高钒含量的渣油原料，研究开发了抗钒催化裂化催化剂。试验表明，沉积在催化剂上的氧化铈抗钒能力较强，能有效地保护分子筛结构不受钒破坏。选用ＳＲＹ和ＲＰＳＡ两种分子筛作为活性组元，使用大孔氧化铝作为粘接剂，制备出催化剂ＣＨＶ－１。工业应用试验结果表明，在原料钒含量和残炭相当或稍高的条件下，ＣＨＶ－１催化剂与原国产催化剂比较，油浆产率下降３．８５个百分点，焦炭产率下降０．２３个百分点，轻质油收率增加３．１７个百分点，液化气收率增加０．２５个百分点，催化剂单耗下降０．４ｋｇ／ｔ，汽油辛烷值（ＲＯＮ）增加１．８个单位。ＣＨＶ－１催化剂整体水平与进口催化剂相当
In order to process the residue of high vanadium residue, the catalyst for vanadium catalytic cracking has been developed. Experiments show that cerium oxide deposited on the catalyst is more resistant to vanadium and can effectively protect the molecular sieve structure from being damaged by vanadium. Two kinds of molecular sieves, SRY and RPSA, were selected as the active component, and macroporous alumina was used as the binder to prepare the catalyst CHV-1. The industrial application test results show that the CHV-1 catalyst has a reduction of 3.85% in oil slurry yield and a decrease of 0.23 in coke yield compared with the original domestic catalyst at the same or slightly higher content of raw material vanadium and carbon residue The light oil yield increased 3.17 percentage points, the yield of liquefied gas increased by 0.25 percentage point, the unit consumption of catalyst decreased 0.4kg / t, and the gasoline octane number (RON) increased by 1.8 units. The overall level of CHV-1 catalyst is comparable to that of imported catalyst
