Report from our correspondent According to statistics, China consumes about 12 million tons of vegetable oil, large and medium-sized city restaurant industry produce used cooking oil 5 million tons, oil mill directly produce waste acid 2.5 million tons of oil.

Now, these are difficult to deal with waste oil had a new purpose and place -- recently, by the Chinese academy of sciences lanzhou compound national engineering research center of fine petrochemical intermediates research and development of cobalt salt catalyst research and development team of "the preparation of biodiesel used cooking oil", won the national invention patent.

The technology can be used to replace petroliferous diesel fuel.


Lanzhou of the Chinese academy of sciences of the group by compound such as food and beverage waste oil, scraps and a mixture of both as a raw material, through to the impurities, dehydration, decarboxylation, esterification, separation and extraction agent distillation steps such as biodiesel.

It is understood that the highest yield of biodiesel obtained by this technique is 92.

4%.

This technology has advantages of high catalyst efficiency, simple production process, short reaction period and low reaction temperature compared with domestic existing technology.


Noun explanation


What is biodiesel?


Biodiesel in oil crops and wild oil plant and engineering micro algae and other aquatic plant oils and animal fats, food waste oil as the raw material made of oil can replace petroleum diesel of renewable diesel fuel, is a kind of biomass energy, has outstanding environmental protection and renewable.


Experts predict that the large-scale bio-diesel industry can be supported by using the reasonable raw materials such as the food waste oil in our country, the oil foot of oil extraction factory, the expired oil of stock and the fruit of tree oil.

If more stable oil sources are established in the future, the scale of China's biodiesel industry will continue to expand.
