早在2008年底中国石油石油化工研究院与中科院大连化物所合作研制出活性高、收率高的新型基础油异构脱蜡催化剂(PIC802)并实现工业应用。此后该课题组进一步调研用户和市场的需求,对异构脱蜡催化剂进行了持续改进,采用新型分子筛载体,开发出二代催化剂,增强了操作的灵活性和产品的选择性。2013年初,第二代润滑油基础油异构脱蜡催化剂(PIC812)在大庆炼化20万t/a高压加氢装置
As early as the end of 2008, CNPC Petrochemical Research Institute cooperated with Dalian Institute of Chemical Physics, Chinese Academy of Sciences to develop a new type of base oil isomerization dewaxing catalyst (PIC802) with high activity and high yield and realize industrial application. Since then, the group further investigated the needs of users and the market, and continuously improved the heterogeneous dewaxing catalyst. The new molecular sieve support was used to develop the second generation catalyst, which enhanced the operational flexibility and product selectivity. In early 2013, the second generation of lube base oil isomerization dewaxing catalyst (PIC812) in Daqing refinery 200,000 t / a high pressure hydrogenation unit
