This technology utilizes waste cooking oil (annual potential feedstock: 7 million tons) to produce biodiesel. It employs a composite catalyst to achieve a one-step reaction at a low temperature of 60℃ , with a yield of 92%. The process is streamlined (feedstock refining-reactionproduct refining), energy-efficient, and eliminates the need for complex separation, while producing glycerol as a byproduct. This project turns waste into treasure, addressing both the pollution caused by waste oil and filling the renewable energy market gap in Northwest China, offering significant environmental and economic benefits.
