Abstract: Disclosed are a preparation method and a system of low-carbon jet biofuel based on whole life cycle. A low-carbon method and a system of using whole life cycle involving whole process from raw material acquisition, fuel preparation to fuel application are related. A prepared jet biofuel can be used in six types of aircrafts and engines thereof. Aircrafts using the jet biofuel can have a portion of greenhouse gas emission reduction of 50% to 80%.

Abstract: A method for grease purification is disclosed. The method comprises steps of: S1, feeding crude grease into a grease hydrolysis column to be hydrolysed so as to obtain aqueous phase, organic phase, and middle layer substances between the aqueous phase and the organic phase; S2, feeding the organic phase and the middle layer substances in the grease hydrolysis column into a flash stripping column to be flashed so as to obtain vaporized products and non-vaporized products; and S3, feeding the vaporized products in the flash stripping column into a separation column to be separated so as to obtain fatty acid. By this method, fatty acid with a high purity can be obtained; glycerin can be obtained as a co-product; and high value-added nutrients in the grease can be collected. Therefore, the use value of grease can be greatly improved.
