In addition, many unscrupulous traders simply process these waste oils, pass them off as "imported oils", and sell them at high prices to make huge profits. Waste oil itself contains a large amount of toxic and harmful substances. Some toxic heavy metals have also been brought into it, which has caused serious harm to the health of consumers.

Abstract

The invention provides an environment-friendly recovered grease decolorizing agent and a preparation method thereof. The environment-friendly recovered grease decolorizing agent is prepared from the following ingredients: water washing acidification rice hull ash, non-water washing-acidification rice hull ash, carbonized soybean hull ash, chitosan, dodecyl dimethyl benzyl ammonium chloride, epigallocatechin gallate, dilauryl thiodipropionate, sorbic acid, butyl p-hydroxybenzoate, ethyl alcohol, hydrochloric acid and water. The preparation method is characterized in that firstly, the chitosan, the hydrochloric acid and the water are mixed, and the mixture is stirred by a magnetic stirrer to obtain a solution A; the sorbic acid, the butyl p-hydroxybenzoate and the ethyl alcohol are mixed and stirred to obtain a solution B; then, the rest ingredients, the solution A and the solution B are mixed, and are then stirred by the magnetic stirrer to be put into a drying box to be dried. The environment-friendly recovered grease decolorizing agent has the advantages that the decolorizing can be fast and effectively performed; meanwhile, partial metal ions are removed; the peroxide value is reduced; the recovered grease quality is improved; in addition, the preparation method is simple and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of decolorizing agents, in particular to an environment-friendly recycled oil decolorizing agent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards in our country, the catering industry in our country is also developing rapidly, and at the same time, a large amount of waste oil in the catering industry has also been produced. This part of oil is mainly contained in the wastewater discharged by the catering industry. If it is directly discharged into the sewer or into rivers and lakes, it will cause serious water pollution. In addition, many unscrupulous traders simply process these waste oils, pass them off as "imported oils", and sell them at high prices to make huge profits. Waste oil itself contains a large amount of toxic and harmful substances. Some toxic heavy metals have also been brought into it, which has caused serious harm to the health of cons...
