Abstract

The invention discloses a production method of biodiesel using Aleurites moluccana fruits as raw materials. The method comprises the following steps: adding a diatomite adsorbent, and carrying out pretreatment for Aleurites moluccana fruit oil in order to obtain pure Aleurites moluccana fruit oil; adding the pure Aleurites moluccana fruit oil, methanol and the magnetic nano-catalyst according to a weight ratio 100:25-35:0.3-0.5 into a reaction vessel for carrying out an esterification reaction; and a biodiesel crude product is separated and purified in order to obtain the biodiesel. The magnetic nano-catalyst is introduced into the esterification reaction with high catalysis efficiency and substantial catalysis effects, so that reaction time is shortened, and yield of biodiesel is increased; on the other hand, the magnetic nano-catalyst can be conveniently and rapidly separated and recycled by means of an exterior magnetic field, and multitime cycle and utilization are carried out. The method also has the advantages of short reaction time, high yield, high product purity, etc.; the method has good social efficiency, ecological benefits, and economic benefits; large scale and industrial production are easy to realize.

Description

technical field [0001] The invention relates to the technical field of biomass energy, in particular to a method for producing biodiesel by using chestnut fruit 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, animal fats, ...
