Research progress on degradation of alcoholamine solution for CO2 capture in flue gas
At present,among the various CO2 absorption and capture technologies,the alcoholamine method is the most widely studied method with the largest amount of absorption and the best economic benefit.However,the degradation of the alcoholamine solution absorbents used in the alcoholamine method is the main defect.In view of the problem of the degradation of alcoholamine solution absorbents,the research progress on products,mechanisms and controls of thermal degradation and oxidative degradation were first reviewed.And then the research progress on mechanisms,rules and controls of metal ion catalytic degradation were reviewed.Finally,the degradation problem of alcoholamine solution absorbents was summarized,and the future research direction of anti-degradation was prospected.
