Abstract

The invention discloses a solid alkali preformed catalyst for biodiesel. The solid alkali preformed catalyst is prepared in the way that papermaking sewage sludge ash is ground, sieved, activated under high temperature and then added to a sodium metasilicate solution, uniform stirring, impregnation and extrusion for anhydration are conducted, then the product is added to a sodium metasilicate solution, and uniform stirring and impregnation are conducted to obtain an impregnation material; clay is added to the impregnation material, and uniform mixing, extrusion forming, drying to a constant weight and calcination are conducted to obtain the solid alkali preformed catalyst for biodiesel. The solid alkali preformed catalyst for biodiesel is high in catalysis activity, the yield of biodiesel is increased, recycle of the waste resource papermaking sewage sludge is achieved, production cost is reduced, and application prospects are broad.

Description

technical field [0001] The invention belongs to the technical field of catalysts, in particular to a solid base shaped catalyst for biodiesel. Background technique [0002] As a high-quality and clean fuel, biodiesel is a kind of biomass energy. Compared with petrochemical diesel, it has the advantages of no sulfur and aromatics, high cetane number, biodegradability, and low environmental hazards. One of the most popular alternative energy sources of petroleum has become an important development direction to solve today's sustainable energy problems. The development of biodiesel industry is beneficial to the country and the people, and is conducive to the harmonious, stable and sustainable development of the society. [0003] Biodiesel production technologies mainly include heterogeneous catalysis, supercritical reaction, enzyme catalysis, homogeneous catalysis, etc. The heterogeneous catalysis method has many advantages such as easy separation of products, simple purifica...
