Preparation method of oil-fat hydrogenation nano catalyst

Abstract

The invention relates to a method for preparing an oil-fat hydrogenation nano catalyst by using nano calcium carbonate. The method is mainly characterized by breaking through the use of a conventional catalyst carrier and adopting nano calcium carbonate which is economical and easily available as a catalyst carrier. The catalyst preparation is simple in operation, the performance of the catalyst is stable, and the hydrogenation effect can reach an industrial requirement level. The catalyst prepared by loading an active ingredient, namely nickel and one or more than one of auxiliary agents, namely aluminum, cobalt, zinc, iron and the like to a carrier namely nano calcium carbonate can be used for hydrogenation reaction of unsaturated fatty acid including branched chain unsaturated fatty acid in natural oil and fat.

Description

technical field

[0001] The invention relates to the field of nano-catalysts, and provides a method for preparing a nano-catalyst for oil hydrogenation by using nano-calcium carbonate as a catalyst carrier. The catalyst provided by the invention can be used for the hydrogenation of unsaturated fatty acids including branched chain unsaturated fatty acids in natural oils. Background technique

[0002] Natural oils exist widely in nature, but due to the existence of unsaturated bonds in natural oils, they are mostly liquid at room temperature, have a low melting point, are easily oxidized by oxygen in the air, change color and taste, and are not easy to store. Oil hydrogenation technology can improve the quality of natural oils, making them widely used in industry and food processing industries. With the rapid development of the oil hydrogenation industry, the research work of catalysts has also been paid attention to.

[0003] The earliest grease hydrogenation catalysts were ...
