Embodiment Construction

[0008] In specific implementation, methanol, ethanol, propanol, butanol, etc. can also be used as substrates. These short-chain alcohols have a denaturing effect on proteins, but have inhibitory properties to the catalysis of lipase, so the number of moles can be according to 1: 1 for deployment, but the alcohol must be injected slowly.

[0009] Combustible gases such as methane produced by fermentation can be used to heat the reaction raw materials.

Abstract

The invention provides a chemical technology for producing bio-diesel from oil by purifying the oil after a fermenting decomposition with microbial algae in a sealed optimized environment. The technology realizes a higher yield and a lower cost for the process can be performed in a sealed fermenting pool, which is suitable for producing bio-diesel and reducing cost.

Description

technical field [0001] The invention relates to biodiesel technology, in particular to a chemical method for converting oil into biodiesel. Background technique [0002] In the current oil conversion technology, basically, in the transesterification reaction of oil and methanol, 1 mole of oil reacts with 3 moles of methanol to generate 3 moles of methyl ester and 1 mole of glycerin; while in the esterification reaction of fatty acid and methanol, 1 mole of fatty acid reacts with 1 mole of methanol to produce 1 mole of methyl ester and 1 mole of water. [0003] The generated water will dilute the concentration of the reactant methanol, thereby greatly reducing the methanol output and slowing down the reaction speed; the treatment method is to use the method of removing fatty acids, which will increase the process flow and cost. Contents of the invention [0004] The invention provides a simplified process for oil conversion and saves cost. [0005] For realizing the above...
