Abstract

The invention discloses a preparation method for biodiesel with Garcinia multiflora Champ as a raw material. The method comprises the following steps: adding a silica gel adsorbent and carrying out pretreatment to Garcinia multiflora Champ oil so as to obtain pure Garcinia multiflora Champ oil; adding the pure Garcinia multiflora Champ oil, methanol and a magnetic nanometer catalyst with a weight ratio of 100: (25-30): (1.0-2.5) into a reaction vessel and carrying out esterification reaction; and subjecting crude biodiesel to separation and purification so as to obtain the biodiesel. According to the invention, the magnetic nanometer catalyst is introduced into the esterification reaction and has high catalytic efficiency and significant catalytic effect, so reaction time is shortened, and the yield of the biodiesel is improved; meanwhile, depending on an external magnetic field, the magnetic nanometer catalyst can be conveniently and rapidly separated and recovered, and a plurality of cyclic utilization can be realized. The method provided by the invention also has the advantages of simple preparation process, energy conservation, environmental protection, short reaction time, high yield, high product purity, etc., has good social efficiency, ecological benefits and economic benefits, and is easy to realize large-scale and industrial production.

Description

technical field [0001] The invention relates to the technical field of biomass energy, in particular to a method for preparing biodiesel by using the bamboo of Mangostifolia as a raw material. Background technique [0002] At present, the contradiction between the continuous growth of global oil demand and the depletion of fossil energy is becoming increasingly prominent, the energy supply situation is becoming more and more tense, the price of crude oil in the international market continues to rise sharply, and the diversification, renewable and clean energy has become the development of human society. It is an inevitable choice. The development of biomass energy is one of the directions to solve the global energy crisis. As a new alternative energy source, biodiesel is developing rapidly in countries all over the world. Biodiesel refers to oil crops such as soybeans, rapeseed, cotton, palm, etc., wild oil plants and engineering microalgae and other aquatic vegetable oils, ...
