【Frontiers in HaiChuan Chemical Technology】CNOOC’s new research project on capturing CO2 to produce high-value products

Thread Content

On December 1, a tender announcement was issued by the Technology R&D Center of CNOOC Gas & Power Group Co., Ltd. for research on CO2 capture, liquid enrichment and conversion as well as the production of high-value-added products. Project Overview: To improve the energy efficiency of the process for capturing CO2 and using it to produce chemicals, this project builds on the research initiative titled “Research on Integrated Technologies for CO2 Capture, Regeneration, and Utilization Using Organic Amine Absorption”. It aims to conduct cutting-edge research on the integrated capture and utilization of CO2 generated after combustion in gas-fired power plants, thereby providing technical foundations for CO2 capture and utilization in such power plants as well as in other scenarios involving point-source CO2 emissions. Since the system does not have the necessary facilities for preparing and testing organic amine solutions, as well as for catalyst synthesis and CO2 capture-regeneration experiments, it is necessary to outsource this part of the research to a company with extensive experience in CO2 capture and chemical conversion. This will enable the acquisition of reliable formulas and synthesis methods for organic amines and catalysts, thereby providing better support for subsequent research and the development of the CCUS industry. Scope of the bidding: 1. Preparation and testing of organic amine absorbents: Prepare organic amine absorbents suitable for cyclic CO2 capture, based on the conditions of flue gases from gas power plants, with a CO2 capture rate of at least 90% ； 2) The organic amine-rich liquid obtained after CO2 capture can react directly with the added reactants in the presence of a catalyst, thereby regenerating the rich liquid into a lean liquid and converting CO2 into the target product ； 2 Catalyst preparation, characterization, and testing: Preparation of heterogeneous catalysts and conductance of catalyst characterization analysis ； Conduct experiments on the regeneration and conversion of the CO2-absorbed rich liquid ； 3 Full-process cyclic experiments and catalyst lifetime experiments. 4 Reaction kinetics of direct conversion for CO2 capture and rich liquid regeneration ； Through simulation, model identification and parameter estimation are carried out using reaction kinetics experimental data.
