WebbHindered amine concept is based on the reaction rates of the acid gases with different amine molecules. ... G.T. Rochelle, in Absorption-Based Post-combustion Capture of Carbon Dioxide, 2016. 3.9.3 PZ blends. Most tertiary and hindered amines react too slowly with CO 2 to provide an acceptable rate of CO 2 absorption. Webb17 dec. 2024 · Conversion of carbon dioxide (CO2) into useful chemicals is one of promising approaches to reduce global warming and the energy crisis. It is pivotal to develop heterogeneous catalytic systems containing task-specific active sites for chemical transformation of CO2. Herein, we report a urea-functionalized imidazolium-based ionic …
