METHOD FOR PREPARING CARBON DIOXIDE ABSORBENT BASED ON NATURAL BIOMASS AND CARBON DIOXIDE ABSORBENT BASED ON NATURAL BIOMASS PREPARED BY THE SAME

摘要

A method for preparing a carbon dioxide absorbent based on natural biomass, and a carbon dioxide absorbent based on natural biomass that is prepared by the method. The method utilizes alkali metal or alkaline earth metal components, such as Ca, Ma and K, inherent to a natural plant biomass material. The method can provide a carbon dioxide absorbent with improved performance in an environmentally friendly manner at greatly reduced cost.
