Description

technical field [0001] The invention relates to a resin-supported solid base catalyst for synthesizing biodiesel from animal and vegetable oils, and specifically discloses a preparation method of the resin-supported solid base catalyst and an application method for catalyzing animal and vegetable oils for transesterification to prepare biodiesel. Background technique [0002] Biodiesel is one of the efficient, clean and sustainable biomass energy. Biomass energy is the solar energy fixed on the earth by the photosynthesis of plants, that is, the biomass energy that can be efficiently utilized is formed by the natural biomass energy conversion technology-photosynthesis of solar energy. Biomass energy can produce various clean fuels through chemical conversion process to replace fossil fuels such as coal, oil and natural gas, which can reduce dependence on fossil energy and reduce environmental pollution caused by energy consumption, so biodiesel is a substitute The environme...
