Description

technical field [0001] The invention belongs to the field of biomass energy, in particular to a continuous catalytic upgrading reaction system for microalgae liquefied oil. Background technique [0002] Microalgae hydrothermal liquefaction technology refers to the process of converting microalgae raw materials into bio-oil under liquid-phase hydrothermal conditions by using thermochemical methods. Hydrothermal liquefaction is a very promising microalgae oil production technology. The production technology of biomass liquid fuel with microalgae as raw material has high economic and technical feasibility; it is of great significance for alleviating environmental pollution and improving energy security . However, microalgae liquefied oil usually has high N, S, and O contents, and poor physical and chemical properties. This kind of bio-oil cannot be used directly and must be upgraded. A very effective method of upgrading is hydrothermal catalytic upgrading. The usual hydrothe...
