Abstract

The invention provides a preparation method of a modified porous silicon material loaded with diethyl succinate and application thereof to carbon dioxide capturing and sealing storage. The preparation method concretely comprises the following steps of adding polyoxyethylene and magnesium chloride into a hydrochloric acid water solution; performing sealed stirring to complete dissolution; adding tetraethoxysilane; performing heating stirring at 40 to 50 DEG C; performing vacuum drying at 100 DEG C; performing natural cooling, filtering and washing; performing sintering for 450 to 600 DEG C to obtain the modified porous silicon material; adding ethanol into the mixture of the diethyl carbonate and diethyl succinate; after the uniform mixing, adding the modified porous silicon material; performing ultrasonic treatment; performing stirring backflow for 2h at 80 DEG C; performing water bath processing at 70 DEG C until the ethanol is completely volatilized; obtaining the modified porous silicon material loaded with diethyl succinate. According to an application method, in heating and pressurizing environment, raw materials containing carbon dioxide and the modified porous silicon material loaded with the diethyl succinate are subjected to reverse flow contact to generate absorption mass transfer; then, temperature reduction and pressure reduction are performed for gas liquid separation.
