Embodiment 1

[0016] 1. 1000kg of refined pepper seed oil A with impurities less than 3‰, 800kg of methanol B with a concentration of 95%, and 15kg of concentrated sulfuric acid C with a concentration of 99% are put into the esterification kettle 1, mixed together, and steamed Heating and maintaining at 62°C, the reaction was continued for 4 hours while excess methanol was vented by distillation.

[0017] 2. After allowing the reactant in the esterification kettle 1 to stand for 2 hours, after draining the acidic water part with a larger specific gravity in the lower part, the remaining reactant is sent to the washing tower 2 for washing to make it neutral.

[0018] 3. After the reactants are washed with water, they are then sent to the dehydration tower 3, which is heated with steam 6, kept at 80°C, and kept stirring for 1 hour, then precipitated for 1.5 hours, and after the water part with a larger specific gravity is discharged from the lower part (this The procedure is called dehydratio...

Embodiment 2

[0022] 1. Put 1000kg of pepper seed oil A with refined impurities less than 3‰ by weight, 400kg by weight of methanol B with a concentration of 98%, and 8kg by weight of concentrated sulfuric acid C with a concentration of 98%, put them in the esterification kettle 1, and mix them together , heated by steam and maintained at 75°C, and continued to react for 8 hours, while discharging excess methanol through distillation.

[0023] 2. After allowing the reactant in the esterification kettle 1 to stand for 1 hour, after draining the acidic water part with a larger specific gravity in the lower part, the remaining reactant is sent to the washing tower 2 for washing to make it neutral.

[0024] 3. After the reactants are washed with water, they are then sent to the dehydration tower 3, which is heated with steam 6, kept at 60°C, and stirred continuously for 1 hour, then precipitated for 1.5 hours, and after the water part with a larger specific gravity is discharged from the lower p...

Abstract

Production of biological diesel oil from pepper-seed oil is carried out by mixing pepper-seed oil with methanol and concentrated sulfuric acid in proportion of 1000:400-800:8-15, reacting, washing reactant by water, dewatering to obtain crude methyl ester, adding into boric acid, distilling and filtering to obtain the final product. It's efficient and has no environmental pollution.

Description

technical field [0001] The invention relates to a production technology of biodiesel, in particular to the technology of making biodiesel from prickly ash seeds. Background technique [0002] For a long time, the energy used by humans mainly comes from coal, oil and natural gas. These energies are non-renewable one-time energies. It is not difficult to imagine that after dozens of hundreds of years, human beings will face the plight of depletion of natural energy; moreover, during the mining, processing and use of these energies, they will inevitably be given to the earth. The living environment of animals and plants has caused serious pollution. In recent years, many developed countries are actively developing new energy sources. Biodiesel is one of the new energy sources that can be artificially synthesized, that is, some plants are used as raw materials to process biodiesel. For example, the United States encourages the use of soybeans and waste ...
