Abstract

The invention discloses a high-quality attapulgite oil decolorizing agent, which is prepared by compounding modified attapulgite, gelatinized modified starch and a cross-linking agent according to a mass ratio of 80-90:(9-14):(2-5). According to the present invention, the attapulgite is subjected to osmotic activation treatment with phosphoric acid to improve the reaction ability of the attapulgite and the chemical reagent, the activated attapulgite is treated with aluminum chloride to improve the surface porosity of the attapulgite so as to improve the adsorption capacity, and then calcination and water cooling are performed so as to enhance the surface activity of the attapulgite is and make the outer surface structure of the attapulgite sparse, such that other substances easily enter the attapulgite so as to establish the new structure in the attapulgite.

Description

Technical field [0001] The invention relates to the technical field of attapulgite, in particular to a high-quality attapulgite oil decolorizer. Background technique [0002] With the development of the edible oil industry and the improvement of people’s living standards, the relationship between edible oils and human health has increasingly become one of the focuses of human attention. The decolorization of oils is one of the most important links in oil refining, and there are many methods for decolorizing oils. , In industrial production, the adsorption decolorization method is often used, that is, some substances that have a strong selective adsorption effect on the pigment are used to adsorb the pigment and other impurities in the grease under certain conditions to achieve the decolorization effect; the attapulgite has low activity Although the decolorization is not as good as the activated clay, the use of its decolorization can reduce the acid return of the decolorized oil ...
