Deacidification adsorbent of grease and preparation method thereof

The invention relates to a deacidification adsorbent of grease and a preparation method thereof. The deacidification adsorbent comprises oil crop seed husks containing an alkaline compound, wherein the content of the alkaline compound contained in the oil crop seed husks is 2-35% by weight, and the oil crop seed husks are one or several of oil-tea camellia husks, peanut hulls, sunflower seed husks, castor husks and walnut husks. The deacidification adsorbent is prepared by activation, pulverization, adsorption and drying treatment. The invention can realize the high-efficiency comprehensive utilization of wastes and also has the advantages of better performance of environmental protection, lower cost and the like. The deacidification adsorbent of the grease has the characteristics of simple preparation process, good adsorption effect and the like and can ensure favorable adsorption capacity and deacidification effect of the adsorbent by controlling the conditions of the activation temperature, the solution concentration and the like. The invention has strong applicability, can be widely suitable for vegetable oil with different varieties and is also suitable for vegetable oil products with low acid value and high acid value. The invention is applied instead of the prior traditional alkali refining method and has no need of any equipment investment.
