Preparation method and using method for paraffin catalyst

Abstract

The invention discloses a preparation method and a using method for a paraffin catalyst, and relates to a preparation method and an application method for a catalyst. The method for preparing the paraffin catalyst comprises the following steps of: adding SBA-15 into water solution of cobalt nitrate; soaking the SBA-15 for 3h at the room temperature; removing the water in a distillation mode; drying the obtained solid for 5h at 120 DEG C; and roasting the solid for 5h at 500 DEG C in the air to prepare an oxidation-state catalyst Co/SBA-15. The prepared paraffin catalyst can be used for catalyzing the oxidized paraffin. The prepared paraffin catalyst has a large specific surface area and aperture; and therefore, the paraffin catalyst is a novel and excellent catalyst of the oxidized paraffin; and moreover, the catalyst is used for catalyzing and preparing the paraffin to obtain the oxidized paraffin with light lustre, light smell and high acid value.

Description

technical field [0001] The invention relates to a preparation method and application method of a catalyst. Background technique [0002] In recent years, with the demand for special waxes in various industries, chemical modification of paraffin waxes by oxidation methods to obtain modified waxes with higher added value has received widespread attention. Because paraffin wax has many excellent properties such as good emulsification, pigment dispersibility, lubricity, oil solubility, etc. after oxidation, it also improves the flexibility of raw wax, so oxidized paraffin wax is used in synthetic biodegradable materials, thermoplastic resins, metal anti-corrosion , textiles, ceramics, lubricating oils, inks, metal surface treatment, ore flotation, leather, coatings, explosives, molding, etc. have been widely used.

[0003] Before the 1980s, the catalysts used for paraffin oxidation mainly used high-priced transition metal soap mixtures with air to produce fatty acids, but the catalyst regeneration effect was not ideal

, in order to immobilize it, people have tried to load it on zeolite molecular sieves, but limited by the diameter of the latter’s pores, these immobilized complexes did not play their due catalytic activity well.
