Embodiment 1

[0033] Example 1 Process raw material A in Table 1, use the catalyst in Table 2 in the hydroprocessing reaction zone, use the catalyst in Table 3 in the hydroisomerization reaction zone, and prepare the hydrogenation and supplementary hydrofining catalyst according to the method in Example 1 of CN00123149.9 , the catalyst is supported by alumina, containing MoO 3 4.5wt%, NiO 29wt%, pore volume 0.31ml / g, specific surface area 180m 2 / g. The results obtained are shown in Table 4. The hydrogenation treatment catalyst is vulcanized by the conventional method, and the hydrogenation treatment reaction is carried out, and the hydroisomerization and hydrogenation supplementary refining catalyst is reduced by the conventional method, and the isomerization or refining reaction is carried out.

Embodiment 2

[0035] Example 2 Treat raw material B in Table 1, use the catalyst in Table 2 in the hydrotreating reaction zone, use the catalyst in Table 3 in the hydroisomerization reaction zone, and use the catalyst developed and produced by Fushun Petrochemical Research Institute for hydrogenation and supplementary hydrofining The properties of the FV-10 catalyst are shown in Table 5, and the results obtained are specifically shown in Table 6. The hydrogenation treatment and hydrogenation supplementary refining catalyst are subjected to hydrogenation treatment and supplementary refining reaction after being vulcanized according to the conventional method, and the hydroisomerization catalyst is subjected to the hydroisomerization reaction after being reduced according to the conventional method.

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 hydroisomerization process. 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 normal paraffins, among which isoparaffin solvent oils have a freezing point Low odor, low toxicity and good stability, etc., widely used in printing and dyeing thinners, ink solvents, metal processing cleaning agents, antirust oils, odorless sprays, odorless oil paints, paints, organosol formulations, dry cleaning of advanced clothes Oil, peroxy organic compound carrier, washing daily chemical products, etc. [0003] At present, the production of isoparaffin solvent oil is mainly based on isoparaffin and olefin as raw materials, through alky...
