Method for refining solvent oil No.200

一种200号溶剂油的精制方法

Abstract

本发明涉及一种用于精制脱氮后润滑油基础油的吸附剂,它含有依次经过溶剂改性、高温活化、粉碎和过筛得到的多孔性凹凸棒石粉末,比表面积为100-200m2/g,含水量小于6%,且90%以上的多孔性凹凸棒石粉末粒径为200-300目;按重量比计,所述多孔性凹凸棒石粉末占吸附剂总重量的70%以上。本发明的吸附剂不仅能降低吸附温度,减少吸附剂用量和能耗,提高油品收率,同时还不产生污染环境。
The invention discloses a method for refining num.200 miscella, including: (1) pretreating: fully contacting the miscella and sodium hydroxide and reacting; (2) adsorbing and denitrifying on a fixed bed: fully contacting and reacting the miscella treated after the step (1) and a compound nitrogen adsorption agent; (3) oxidizing and promoting: fully mixing and treating the miscella treated after the step (2) and an oxidation promoter; and (4) oxidizing, catalyzing and deodorizing on the fixed bed: fully contacting and reacting the miscella treated after the step (3) and a catalyst. By using the method, an alkaline nitride content of the refined miscella is removed to less than 1PPm, a mercaptan content is removed to less than 1PPm, the refined oil is colourless and odourless, and Sybolt chroma thereof is not less than 25, and storage stability is good.
