Abstract

Disclosed are a graphene aerogel, a regenerated catalyst and the use thereof, and a method for regenerating a CO₂-rich amine solution. The B acid content of the graphene aerogel is 0.001-0.05 mmol/g, the specific surface area thereof is 40-200 m²/g, and the ratio of the volume of pores having a pore diameter of 20 nm or below to the total pore volume of the graphene aerogel is not smaller than 50%. The graphene aerogel is applied to a regenerated catalyst of a CO₂-rich amine solution, and is helpful in catalyzing the desorption of CO₂, reducing the initial temperature and finish temperature of desorption, increasing the desorption rate, shortening the desorption time, reducing the desorption energy consumption and increasing the desorption quantity.
