Abstract

The invention discloses a method for electrocatalysis combined with algae participating in the utilization of oily waste water. The algae biomass is selected, the oily waste water and the algae biomass are mixed, the mixed raw material is added to an intermittent high-temperature and high-pressure reaction kettle, and the catalyst is added and sealed. , put the reaction kettle into the salt bath furnace to heat to start the hydrothermal liquefaction reaction, and obtain the liquid phase product of the hydrothermal liquefaction reaction; put the liquid phase product into the electrolytic cell as the raw material for electrocatalysis, and perform electrocatalysis with the help of the electrolyte After the reaction is finished, the upper oil phase is collected to obtain refined bio-oil. The method of the invention can improve the utilization of algae biomass, and provides an effective way for effectively utilizing waste resources of oily wastewater to generate economic benefits.

Description

technical field [0001] The invention belongs to the field of algae biomass utilization and environmental protection, in particular to a method for electrocatalysis and algae participating in the utilization of oily wastewater. Background technique [0002] Hydrothermal liquefaction of wet biomass such as algae is a promising method for producing renewable and sustainable energy alternatives to fossil fuels. Hydrothermal liquefaction is a thermal depolymerization process that converts wet biomass into crude oil (bio-oil) at a medium temperature of 200-380°C and a high pressure of 5-20 MPa. In the hydrothermal liquefaction process, water is the reaction solvent, and the organic solvent is the co-solvent (which may or may not participate in the reaction). Biomass hydrothermal liquefaction products include oil phase (bio-oil, the main product), solid phase (biochar), gas phase, water and other phases. When wet biomass such as algae is used as a feedstock for fuel production, h...
