RAs－2（B）脱砷剂的首次工业应用

FIRST APPLICATION OF RAs-2 (B) DEARSENIC AGENT IN DAQING PETROCHEMICAL COMPLEX

大庆石油化工总厂于１９９０年７月与１９９１年１０月分别在新建的３０万ｔ／ａ焦化汽油与常顶汽油混合原料的加氢精制装置和改造后的１５万ｔ／ａ重整装置上应用石油化工科学研究院研制的ＲＡｓ－２（Ｂ）脱砷剂。经ＲＡＳ－２（Ｂ）脱砷剂处理的原料油含砷量分别降低了７０％和９９％以上，使加氢精制ＲＮ－１主催化剂使用寿命延长两年左右。

This paper summarizes the commercial application of dearsenic agent RAs-2 (B), developed by RIPP,in Daqing Petrochemical Complex. The new hydrorefining unit of 300,000 t/a for mixedfeedstock of coking naphtha and straight-run naphtha was straied in July, 1990, and the revamped reforming unit of 150, 000 t/a was started in October, 1990. Consequently, with treatment of RAs-2 (B) arseniccontent in feedstock decreased more than 70% and 99% respectively. As a result, lifetime of catalysttreated with dearsenic agent, has prolonged about 2 years
