Title:
RENEWABLE-ENERGY-DRIVEN SYSTEM AND METHOD FOR SYNTHESIZING FORMIC ACID BY MEANS OF CARBON DIOXIDE HYDROGENATION
Document Type and Number:
WIPO Patent Application WO/2023/035491
Kind Code:
A1
Abstract:
The present application belongs to the technical field of renewable energy utilization and greenhouse gas emission reduction, and specifically relates to a renewable-energy-driven system and method for synthesizing formic acid by means of carbon dioxide hydrogenation. The system comprises a carbon dioxide capture apparatus, a hydrogen production apparatus, a formic acid synthesis apparatus and a renewable energy power generation apparatus. By means of cooperation among the apparatuses, the system can directly use carbon dioxide in the air and surplus electric energy of the renewable energy power generation apparatus to synthesize high-energy formic acid, such that serious waste of renewable energy in the troughs of electricity consumption is reduced, so as to solve the problem of electricity curtailment of renewable energy, and the content of carbon dioxide greenhouse gas in the air is also reduced. In addition, resource utilization of the carbon dioxide gas is further realized, the high-energy compound formic acid is obtained, and the transportation cost of raw materials is reduced.
