Method for manufacturing biological diesel oil

Abstract

The present invention relates to a manufacturing method of biodiesel, aiming to provide a method used to convert the polluted waste of hogwash oil and waste oil into biodiesel. The steps are that: a. raw oil is deglued and dehydrated through acid cleaning to obtain pure fatty acid; b. the fatty acid is mixed together with sodium hydroxide, biological enzyme used as catalyst and methanol, c. the mixture is added into a reaction vessel, stirred ceaselessly and heated simultaneously, and when temperature rises to 70 DEG C, esterification reaction is completed and fatty acid methyl ester is generated; d. the material after reaction is taken out, and a plurality of bigger particles are filtered out by a filtering machine, thus the pure fatty acid methyl ester can be obtained; e. a part of petrochemical diesel is added into the fatty acid methyl ester extracted out, and the biodiesel can be obtained. The biodiesel manufactured by the present invention can be used for automobiles, steamship, generators and other machines.

Description

【Technical field】 [0001] The invention relates to biodiesel, in particular to biodiesel for vehicles produced by utilizing hogwash oil and gutter oil. 【Background technique】 [0002] Diesel oil sold on the market is basically a product of petroleum refining, i.e. petrochemical diesel oil, which is a non-renewable resource. In the process of its production, processing and use, there is still a very explosive hidden threat to the natural ecological balance. Signs show that the world's oil production is approaching the highest peak in history. If the energy reserves of industrial countries decline at a rate of 2% per year, while solar and wind power can only meet 1% of demand, industrial countries will definitely enter economic depression or even develop To the stage of economic stagnation, and the competition for dwindling energy reserves and untapped base will intensify. Since 2003, my country has become the world's second largest oil consumer after the United States, and it...

There are also people working in this area in our country, such as the Chinese patent application 92114795.3, which uses natural oils to produce biodiesel, which cannot be widely used due to the high price of raw materials

[0003] Hogwash oil and waste oil are polluting wastes produced in the daily operation of the catering industry. my country’s huge catering industry produces a large amount of hogwash oil and waste oil every year. In order to deal with these wastes, the country spends a lot of money every year. In some places If the disposal funds are relatively small, they are discarded, polluting the environment, some are directly fed to pigs, and some are even returned to the dining table, causing people to be poisoned and seriously affecting people's physical and mental health
