CARBON DIOXIDE CAPTURE AND CONVERSION TO A CARBAMATE SALT AND POLYUREA

摘要

A method for treating carbon dioxide includes preparing a polyamine composition and delivering a stream containing carbon dioxide to the polyamine composition. The carbon dioxide reacts with polyamine in the polyamine composition to form a carbamate salt. A method for producing polyurea from carbon dioxide includes delivering a stream containing carbon dioxide to a polyamine composition. The carbon dioxide reacts with polyamine in the polyamine composition to form a carbamate salt. The method also includes dehydrating the carbamate salt to produce polyurea.
