Description

technical field [0001] The invention relates to a device and a process for producing bio-based fuel oil by catalytic cracking of self-heating oil, belonging to the technical field of bio-energy. Background technique [0002] With the development of economy and society, the problems of energy shortage and environmental pollution have attracted more and more attention. Fossil energy such as coal, oil, and natural gas not only has limited reserves, but also emits a large amount of pollutants after combustion, which poses serious environmental problems. Therefore, biomass energy as an alternative to fossil fuels has attracted much attention. As a common biomass raw material, animal and vegetable oils and fats are valued by researchers because of their good renewability and unaffected by regional natural conditions. Catalytic cracking of animal and vegetable oils into bio-based fuels greatly improves the quality of animal and vegetable oils and expands the application range of ...
