Abstract

The invention discloses a biodiesel production method which comprises the following steps: inoculating crypthecodinium cohnii to a medium; irradiating for 10-14h per day with a red-blue double-color LED fill light; culturing for 6-7 days at 23-26 DEG C to obtain organic crypthecodinium cohnii cells; performing wall breaking treatment of the collected crypthecodinium cohnii cells, and extracting with an organic solvent to obtain microalgae oil; adding the microalgae oil, methanol and a zeolite molecular sieve catalyst into a reactor according to a mass ratio of 1:(5-7):(0.01-0.04) for an esterification reaction to obtain an esterified product; and separating and purifying the esterified product to obtain the biodiesel. In the method disclosed by the invention, by adopting the crypthecodinium cohnii with short production cycle, wide distribution, strong photosynthesis and high oil content as a raw material, the problems of vegetable oil raw material in biodiesel development are solved. The method also has the advantages of simple preparation technology, high catalysis efficiency, high oil extraction rate, high product yield and the like and lays a good foundation for the industrial and large-scale production of biodiesel.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, in particular to a method for producing biodiesel. Background technique [0002] With the increasing depletion of fossil fuels and the sharp rise in oil prices, the search for renewable energy has become a solution to human survival and to maintain the sustainable development of the world economy. As a new alternative energy, 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, and catering waste oils, etc. Renewable diesel fuel to replace petrodiesel. The advantages of biodiesel are not limited to renewability. Compared with existing diesel, it also has the following advantages: high cetane number, which makes the combustion performance better; better wetting performance, which makes the fuel injection pump, en...
