Converting waste cooking oil into biofuel

Scientists from the Institute of Chemistry - Vietnam Academy of Science and Technology have successfully researched the method of converting waste cooking oil into biofuel by catalyzing cracking reaction.

The results from this study not only bring about economic benefits, minimize the negative effects of cooking oil on human health and the environment, but also help partially solve the bioenergy problem in future.

Biofuels can be prepared from vegetable oils by various methods

Waste oil before being used as raw material for conversion into biofuel is treated to remove impurities, residue and recover about 56% by absorption method. After a catalytic cracking reaction to this amount of cooking oil will produce a number of products including dry gas, gasoline, diesel and some other energy products.

In the world, biofuel can be prepared from vegetable oil by many different methods such as pyrolysis, gasification but cracking method catalyzes the clear advantage of the conversion of waste cooking oil into Biofuel rate is 83% compared to the pyrolysis method of 30%. Moreover, the percentage of gasoline obtained by this method is also much higher than that of pyrolysis method (38.18% compared to 23.52%).

The Institute of Chemistry is continuing to research and develop the obtained results, contributing to finding new directions for Vietnam's biofuel manufacturing industry, soon applying biofuels widely in practice.
