Title:
METHOD FOR PREPARING BIODIESEL BY USING DUAL MOFS IMMOBILIZED LIPASE
Document Type and Number:
WIPO Patent Application WO/2022/227122
Kind Code:
A1
Abstract:
Disclosed is a method for preparing biodiesel by using dual MOFs immobilized lipase, which comprises the following steps: preparing ZIF-8; preparing ANL/ZIF-8 by using ZIF-8; preparing a three-dimensional ordered polystyrene template; preparing M-ZIF-8 by using the three-dimensional ordered polystyrene template; preparing ANL@M-ZIF-8 by using M-ZIF-8; and mixing an oil, a short-chain alcohol, ANL/ZIF-8, and ANL@M-ZIF-8 for reaction, so as to obtain biodiesel. The present invention simultaneously uses ANL/ZIF-8 and ANL@M-ZIF-8 as dual MOFs so as to prepare biodiesel, which not only solves the problem in which the pore size of a single MOFs mesoporous structure is insufficient and inhibits the catalytic synthesis effect, but also integrates the physical and chemical properties of the mesoporous structures of two MOFs, to form a multi-layered porous adsorption structure, thereby greatly improving the yield of biodiesel.
