The Hong Kong Polytechnic University (PolyU) won 15 awards at this year's 43rd International Invention Exhibition in Geneva. PolyU's Department of Applied Biology and Chemical Technology, Dr. Rong Jiafu, said that he invented a catalyst that can catalyze the production of biodiesel from waste oil. This invention won the gold medal for the invention exhibition.
By mastering the precise technology of controlling the surface chemistry of materials, Rong Jiafu's research team developed a new type of green biodiesel solid catalyst that has high activity and longevity for biodiesel raw materials.
Rong Jiafu introduced his invention to reporters. The catalyst is a solid metal oxide. It is synthesized in a simple manner. It is non-toxic and insoluble in water or oil. It can solve the sewage generated in traditional liquid catalysts and greatly reduce energy consumption. Cost and pollution.
Rong Jiafu stated that the raw material of biodiesel can be vegetable oil, animal oil, or waste oil. The catalyst catalyzed by the catalyst can be directly applied to the current diesel supply system, and the fuel can be completely burned, which can reduce the emission of carbon monoxide by about 80%. Fuel cost Can be reduced by half while reducing engine losses.
The invention can be applied to traditional transportation tools such as trains, buses, and ships.
Rong Jiafu said that the current cost of biodiesel production is high, but the future production costs will become lower and lower. The next step in the industrial sector needs to consider improving production processes and large-scale production and transform scientific inventions into truly useful market-oriented products. .
