Title:
BIO-OIL ELECTROCHEMICAL UPGRADING METHOD AND BIO-OIL ELECTROCHEMICAL HYDROGENATION UPGRADING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/021909
Kind Code:
A1
Abstract:
The present invention relates to the field of biomass energy utilization. Disclosed are a bio-oil electrochemical upgrading method and a bio-oil electrochemical hydrogenation upgrading device. The bio-oil electrochemical upgrading method comprises the following steps: (a) mixing bio-oil, an organic solvent, and a supporting electrolyte to obtain a catholyte; (b) preparing an acid solution as an anolyte; (c) constructing an electrochemical reactor by using the catholyte and the anolyte, and separating the catholyte from the anolyte by means of one or two ion exchange membranes, thus forming a current loop; and (d) introducing a protective gas into one side of the catholyte, and then introducing current by means of a working electrode and an anode electrode to perform electrochemical reaction, thereby implementing the electrochemical upgrading of the bio-oil. According to the present invention, the problem that carbon deposition is easily formed when the bio-oil is upgraded by a thermochemical method can be effectively solved, the bio-oil is subjected to electrochemical upgrading under mild conditions, and the content of bio-oleic acid, the content of aromatic components and the content of heavy components can be reduced by upgrading, so that the bio-oil is suitable for transportation and storage.
