Abstract

The invention relates to a method for preparing biodiesel by using animal fatty acid ethyl ester, belonging to the technical field of biodiesel preparation. The method has the advantages of simple technology, environmental protection, high efficiency and low cost. The technical scheme is that the method for preparing biodiesel by using animal fatty acid ethyl ester comprises the following steps (prepared by weight parts) that: step one: 10 parts of combustion alcohol by weight is taken and 1-2 parts of antioxidant by weight are added; step two: the mixture is heated to 50-60 DEG C; and the mixture is electromagnetically agitated for 10-20 minutes to reach full dissolution; and step three: 100 parts of antioxidant solution are added into 10000-15000 parts of animal fatty acid ethyl ester to obtain the biodiesel and the biodiesel is contained in common diesel barrels or diesel tanks; and the antioxidant is vitamin E or vitamin C. The method is used in the technical field of biodiesel.

Description

technical field [0001] The invention discloses a method for producing biodiesel from tallow fatty acid ethyl ester, belonging to the technical field of producing biodiesel. Background technique [0002] We all know that fossil fuels are finite resources. The ecological energy industry will gradually become a pillar industry on which the national economy depends. Biodiesel is a clean renewable energy. It is a liquid fuel made from oil crops, oil tree fruits, animal fats, and waste cooking oil. It is a high-quality substitute for petroleum diesel and a typical "green energy". Vigorously developing biodiesel has important strategic significance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution. As a biodiesel fuel, it not only has good fuel performance and safety performance, but also has excellent environmental protection characteristics and renewable performance. In addition, biodiesel ...
