CARBON DIOXIDE ABSORBENTS USING MESOPOROUS MATERIAL AND CARBON DIOXIDE REMOVAL METHOD USING THE SAME

摘要

PURPOSE: A carbon dioxide absorber using meso-porous materials and a carbon dioxide eliminating method using the same are provided to increase an area, to which carbon dioxide is absorbed, based on branches of polyethyleneimine. CONSTITUTION: A carbon dioxide absorber includes meso-porous materials and polyethyleneimine. The average molecular weight of the polyethyleneimine is between 450 and 650. The polyethyleneimine is immersed in the meso-porous materials. The meso-porous materials are MCM-41 or MCM-48. The absorber absorbs carbon dioxide at a temperature between 40 and 80 degrees Celsius. The immersing rate of the polyethyleneimine is M2/(M1+M2)x100 and is in a range between 25 and 35 wt%, between 45 and 55 wt%, or between 65 and 75 wt%. The M1 is the content of the meso-porous materials. The M2 is the content of polyethyleneimine.
