Preparing method of amine-grafting silica gel support for dry-type adsorption of carbon dioxide

摘要

The present invention relates to a process for producing an amine-modified silica gel support for carbon dioxide adsorption, which comprises a single step of adding an amine modifier, ammonia, and a pore-forming agent to an aqueous solution of a silicon composition to be mixed, The silica gel support is formed, which can reduce the processing time and manufacturing cost, and has an excellent carbon dioxide adsorption amount.
