Document Type and Number:

WIPO Patent Application WO/2020/133849

Kind Code:

A1

Abstract:

The present invention relates to the field of polyunsaturated fatty acid treatment, and disclosed thereby are a hybrid adsorbent and an application thereof, and a method and equipment for treating polyunsaturated fatty acid. Said hybrid adsorbent contains aluminum oxide and copper salt modified zeolite molecular sieves, and preferably further contains at least one of argil, attapulgite, silicon dioxide and activated carbon. The aluminum oxide is neural aluminum oxide and/or acidic aluminum oxide. The hybrid adsorbent provided by the present invention is supplemented by ultrasonic activation, and accordingly is comparable to silica gel in the aspects of decolorization and aldehyde ketone quinone removal, and basically will not result in loss of other nutritional components in grease. Meanwhile, the merits of low cost, easy regeneration and good product stability are still retained.
