Abstract

The invention discloses a microalga-based biomass refining method and a system for implementing the microalga-based biomass refining method. The method comprises the following steps: S1, pretreating microalgae to obtain dry alga powder; S2, separating components of the dry alga powder to obtain alga oil, proteins and polysaccharides; and S3, performing pyrolysis on the alga oil for upgrading to obtain diesel, performing pyrolysis on the proteins for upgrading to obtain aromatic hydrocarbons, and performing pyrolysis on the polysaccharides for upgrading to obtain gasoline. Therefore, by adopting the microalga biomass as a raw material source, the refining method also realizes co-production of multiple oil products such as gasoline, diesel and kerosene on the basis of realizing co-productionof coke, fuel gas and oil products, and promotes the conversion from the petroleum-based refining industry to the bio-based refining industry. Furthermore, the refining method can select different raw materials for different needs of gasoline, diesel and kerosene in actual production activities, thereby flexibly adjusting the yields of bio-based liquid fuels and greatly improving the economy.

Description

technical field [0001] The invention relates to the technical field of microalgae treatment, in particular to a microalgae-based biomass refining method and a system for implementing it. Background technique [0002] With the deterioration of the global warming effect and the increasing shortage of fossil energy, the research on bio-based liquid fuels has received more and more attention. As a third-generation biofuel raw material, microalgae biomass has a fast growth cycle, CO 2 It has the characteristics of high fixation efficiency, photosynthetic efficiency significantly higher than that of terrestrial plants, and high oil content. However, biomass itself has low energy density and is incompatible with the existing liquid fuel transportation and utilization system. Therefore, converting solid microalgae biomass into liquid fuel is one of the necessary ways to utilize it. Pyrolysis is a relatively mature technology in liquefaction technology. However, the main biochemi...
