摘要

Biodiesel was prepared with microalgae oil under supercritical methanol condition. The calorific value, chemical composition, molecular structure, and fuel behaviors of the as-prepared biodiesel were characterized by several means. All the results show that most fuel performances of the product oil resemble those of the fossil diesel except for the low-temperature performance. The product oil has long molecular chains and many unsaturated double-bond structures. In this meaning, the biodiesel is suitable to be mixed with fossil diesel or to be added to pour point depressant for industrial application.
