Abstract

Biofuel is a renewable fuel. Due to global warming, oil crisis and other factors, biofuel is receiving increasing attention. Biofuel is the fuel extracted from biomass, which has the advantages of diversity, materiality, recyclability and environmental protection. It is mainly used for road transportation. According to the evolution of biofuel, its production process has gone through four iterations, so far the research of biofuel is still in constant exploration. This review summarizes the common biofuel, among which bioethanol and biodiesel are well known and widely used. We should have a correct understanding and view of biofuel, and scientifically face the difficulties and challenges that will be encountered.
