The invention uses immobilized microbial lipase to catalyze the synthesis of fatty acid lower alcohol esters in a non-aqueous phase system. Lipase is immobilized on an inert carrier film or textile, and the immobilized carrier can be combined with a wire mesh to form a new type of reactor, which catalyzes the esterification reaction of fatty acids and alcohols in the organic phase within the range of 20-60 ° C, 14 -24hr esterification rate can reach 90-97%. Compared with the current industrial process of esterification using chemical catalysts under high temperature and high pressure, this method has the advantages of mild reaction conditions, low energy consumption, strong reaction specificity and less by-products. Compared with similar enzymatic synthesis processes, the method has the characteristics of easy separation of the product from the immobilized enzyme, which is beneficial to continuous production and easy recovery and repeated use of the immobilized enzyme. At the same time, adding a water-absorbing agent during the reaction can shorten the reaction time and increase the esterification rate. The product transformed by the method has light color and high quality, and has important applications in the fields of energy, agriculture, textile, plastics, food, cosmetics and the like.

The invention discloses a catalyst for organic wastewater treatment and a preparation method thereof. The catalyst is prepared by coating a cobalt-doped composite material layer on a granular silicon-containing carrier. The thickness of the cobalt-doped composite material layer is 100-240 nm. The cobalt-doped composite material layer takes a silicon oxide-titanium oxide composite layer as a base body and cobalt as an enhancer. The molar ratio of the enhancer to the base body in the cobalt-doped composite material layer is 1: (50-200). The molar ratio of silicon oxide to titanium oxide in the silicon oxide-titanium oxide composite layer is 1: (1-3). The catalyst is good in catalytic effect and long in service life.
