Problems solved by technology

However, the catalytic hydrogenation reaction generally requires medium pressure or high pressure, at least a few MPa pressure, and the requirements for equipment and catalyst are relatively high, which brings certain difficulties to the operation of workers and is difficult to be widely used in actual factories. During the operation

Abstract

The invention provides a preparation method for a bimetallic mineral spirit refining adsorbent. The method comprises the following steps: (1) pretreatment: drying and activating a molecular sieve; (2) ion exchange: mixing the molecular sieve activated in the step (1) with a metal nitrate solution for ion exchange, and drying the exchanged molecular sieve; (3) impregnation: isovolumetrically impregnating the molecular sieve dried in the step (2) by using another metal nitrite solution, and drying the impregnated molecular sieve; (4) calcination: calcining the molecular sieve dried in the step (3) to obtain the bimetallic mineral spirit refining adsorbent. The bimetallic mineral spirit refining adsorbent is applied to the removal of impurities such as olefin and arene from 6#, 120# and 200# mineral spirits for refining at normal temperature, the treatment process is simple, and remarkable olefin and arene removal effects are achieved.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a bimetallic petroleum spirit refining adsorbent and its preparation method and application. Background technique [0002] Solvent oil is one of the five major categories of petroleum products. Solvent oil has a wide range of uses. It is a light petroleum product used to dissolve, dilute, wash and extract certain substances. Paint solvent oil (commonly known as paint solvent oil) is the most widely used, followed by edible oil, printing ink, leather, pesticides, insecticides, rubber, cosmetics, spices, medicine, electronic components and other solvent oils. The world consumes about 20 million tons of various petroleum spirits every year, of which petroleum petroleum spirits account for about half. Before the 1980s, there were fewer varieties of petroleum spirit, and the properties did not change much. However, in the late 1980s, with the increasingly stringent environmenta...
