摘要
介绍了ZCG-1型增产汽油催化裂化催化剂在中国石化北京燕山分公司炼油二厂Ⅱ套重油催化裂化装置上的工业应用情况及标定结果。结果表明:该催化剂能适应催化裂化原料重质化和劣质化性质的改变,具有较强的裂化能力、抗重金属污染能力,具有较好的焦炭选择性和较高的汽油选择性;在掺炼减压渣油比例为51.26%(w)时,汽油收率达到48.80%,比使用VRCC-1催化剂时提高约6百分点,液体收率达到82.45%,产品分布良好,且经济效益显著。
The industrial application of ZCG-1catalyst in the RFCC unit of SINOPEC Beijing Yanshan Company was introduced.The results of application indicate that ZCG-1catalyst shows excellent residue cracking ability,resistance to heavy metal contamination and good coke selectivity,especially gasoline selectivity.When the feedstock contains 51.26%（w）residue,the gasoline yield reaches48.80%（w）,increased by 6.0percentage points than the former catalyst VRCC-1and the liquid yield maintains at 82.45% with a good product distribution and a remarkable economic benefit.
