Method for producing biological diesel oil

Abstract

The invention relates to a method to produce bio-diesel. The invention includes the steps as follows: firstly materials with parts by weight are weighed, including cottonseed extract (10), rapeseeds extract (10), rapeseeds shell (3), olive tree (2), palm (2), rapeseeds stem (10), biogas liquid (2), waste animal lipid (3), rapeseeds extract (5), and slop oil (43); secondly the materials are mixed and stored in a recycling pool, thirdly caustic soda as the additive is added to the recycling pool, the smashed camphortree as the non-synthesized additive is added with a ratio; fourthly all materials are mixed for derivation and fermentation for three weeks, fifthly the fermented mixture is sent to a smashing workshop to be smashed, sixthly the smashed mixture is sent to a filtering workshop tobe filtered, with the filtered liquid of every filtering stage sent to a high-pressure workshop to be refined and, seventhly the mixture is evaporated by boilers in the high-pressure workshop to obtain a liquid, then the evaporated liquid is cooled down and conveyed to the storage can, and then the liquid is conveyed to a three-phase separator to be refined to obtain glycerin and rough methyl acrylate and; eightly the rough methyl acrylate is fed into a refining procedure to be refined into methyl acrylate, i.e. the bio-diesel.

Description

technical field

[0001] The invention relates to a method for refining oil, in particular to a method for producing biodiesel. Background technique

[0002] As a renewable energy source, biodiesel is the fourth largest energy after coal, oil, and natural gas. It occupies an important position in the entire energy. The application of bioenergy can partially replace conventional energy such as coal and ease the current tension in energy supply. , biodiesel can be used in China will be promising. Due to the rising international oil prices, renewable energy such as biomass, sun, water and geothermal has gradually replaced mineral energy in recent years. Biomass energy includes fuel ethanol, biodiesel, biomass power generation and biogas. At present, many countries have proposed biofuel development goals. The United States plans to replace 10% of crude oil consumption with bioenergy and 25% of petrochemical raw materials with bio-based products in 2020. In the current production...
