Problems solved by technology

[0003] However, the existing solid amine adsorption materials all have the problem of insufficient stability.
This is because the organic amine loaded in the material is easy to dissolve, volatilize, leak, oxidize, and remove CO at high temperature. 2 also produces urea and cyclic urea, resulting in permanent inactivation
In addition, the existing solid amine adsorption materials usually use mesoporous silicon as the matrix, and the pores are easily blocked by water vapor in the flue gas. Therefore, in the adsorption and separation of CO 2 Before, the flue gas must be dehydrated, resulting in a significant increase in energy consumption and investment costs

Abstract

The invention discloses a polyacrylate composite material for CO2 adsorption, which is prepared by the following steps of: carrying out amination grafting on porous polyacrylate, and carrying out epoxy resin surface end-capping treatment to obtain the polyacrylate composite material for CO2 adsorption. The invention has the following advantages: the synthesis process is simple, and the price is low; the three-stage interconnected pore structure meets the requirement for rapid adsorption/desorption of CO2, does not cause blockage of pores by moisture in flue gas, is uniform in particle size distribution and controllable in ball size, and can better meet the requirement of a fluidized bed.

Description

technical field [0001] The present invention relates to a method for CO 2 Adsorbed polyacrylate composites and methods for their preparation, belonging to CO 2 separate fields. Background technique [0002] As we all know, CO 2 Emissions are one of the important causes of climate warming. The global burning of fossil fuels produces CO 2 About 35.5Gt, while the carbon sequestration of green plants is less than 6%. This serious imbalance between man-made emissions and natural consumption makes the CO in the atmosphere 2 Concentration increased sharply. my country's annual CO 2 The emission is about 10Gt, and the energy structure dominated by fossil energy will not change in the near future. Carry out large-scale CO 2 Capture and utilization have attracted more and more attention. in various CO 2 Among the separation methods, the alcohol amine solution absorption method has high separation efficiency, wide application range and high product purity. It is a relatively ...
