It is reported that the biodiesel samples produced by the company without any additives have reached the German biodiesel standard. At present, the biodiesel production plant with an annual output of 20,000 tons has been built and put into mass production. This new catalyst technology can change the original reaction process, so that the waste animal and vegetable oil and methanol can be esterified and alcoholized in one step in the same container, which not only improves the conversion rate, but also reduces the production cost per ton of biodiesel 300 yuan. The successful development of this technology has attracted great attention from the Ministry of Science and Technology, and the technology (product) of this project has been included in the National Key New Product Plan, the Tenth Five-Year Plan and the National Torch Plan.
At present, biodiesel production at home and abroad mainly uses animal and vegetable oils and low-carbon alcohols, such as methanol or ethanol, to generate corresponding fatty acid methyl ester or ethyl ester at high temperature in the presence of acidic or alkaline catalysts. Because alkaline catalysts have high requirements for crude oil, only unrefined rapeseed oil and soybean oil can meet the requirements, so the cost of raw materials accounts for 75% of the total cost.
In addition, unsaturated fatty acids are easy to deteriorate at high temperature, and esterification products are difficult to recover, and waste lye is discharged during production, which affects the ecological environment. Fujian Longyan Zhuoyue New Energy Development Co., Ltd., a key high-tech enterprise of the National Torch Program, has solved the above problems by relying on new catalyst technology, and its products are more environmentally friendly and cheaper than mineral diesel.
