Technology for obtaining a domestic catalyst for hydrogenation of vegetable oils

Abstract

Vegetable oils are obtained from oil-containing sunflower seeds, burdock, flax, rapeseed, corn, soybeans, etc. The composition of vegetable oils contains esters (triglycerides) of fatty acids with varying degrees of unsaturation. One of the main processes of vegetable oil processing is the hydrogenation process. Hydrogenation of vegetable oils is a widespread technological process of obtaining raw materials for the production of confectionery fats, detergents, soaps, stearin and other products. It is the hydrogenation of vegetable oils that is of great importance, because it increases the volume of food production. Catalysts for hydrogenation of vegetable oils are not produced in Russia. The volume of the import market is about 250 tons per year. The development and production of domestic catalysts is a priority task in solving import substitution problems. The paper suggests the most environmentally friendly and economical way to obtain catalysts of various chemical compositions is the method through an ammonia-carbonate complex. The results of reserve tests of the developed samples of nickel catalyst for hydrogenation of vegetable oils, as well as the conclusion of potential consumers are presented.
