Abstract

The invention provides a preparation method of a low-carbon biological aviation fuel based on full life cycle. The preparation method includes the steps: S1 screening micro-algae coupled with carbon spectrum characteristics of the aviation fuel; S2 cultivating the micro-algae to obtain oil-producing micro-algae with an efficient carbon dioxide fixation function and high fatty acid yield; S3 extracting grease from the oil-producing micro-algae by a hydrothermal method to obtain raw oil containing the grease; S4 sequentially performing impurity removal and hydrorefining treatment on the raw oil to obtain a hydrogenated product; S5 fractionating the hydrogenated product to obtain a kerosene component and a gasoline component, wherein the gasoline component is the biological aviation fuel. The prepared biological aviation fuel can be applied to six types of engines-aircrafts, and full life cycle greenhouse gas emission reduction proportion can reach 50-80% by the aid of the biological aviation fuel.
