Abstract

The invention discloses a method for manufacturing an isoparaffin solvent oil. By utilizing distillate or light deasphalted oil and the like as a raw material, the isoparaffin solvent oil is manufactured by the integrated process of hydroprocessing-hydrogenation isomerization-hydrofinishing. With the method of the invention, high-quality isoparaffin solvent oil products of various fractions can be manufactured with ordinary raw oil. The method has the characteristics of good raw material adaptability, good quality of products, flexible manufacturing and the like.

Description

technical field [0001] The invention relates to a method for producing isoparaffin solvent oil, in particular to a method for producing isoparaffin solvent oil by adopting a combined process of hydrogenation and isomerization. Background technique [0002] Solvent oil products are one of the five major categories of petroleum products. Solvent oil products can be divided into aromatic hydrocarbons, dearomatized aliphatics, isoparaffins, naphthenes and n-paraffins, among which isoparaffins have a freezing point. Low odor, low toxicity and good stability, widely used in printing and dyeing thinner, ink solvent, metal processing cleaning agent, anti-rust oil, odorless spray, odorless oil paint, paint, organic sol formulation, advanced clothes dry cleaning Oil, peroxy organic compound carrier, washing and daily chemical products, etc. [0003] At present, the production of isoparaffin solvent oil mainly uses isoparaffin and olefin as raw materials, through alkylation reaction, ...
