METHOD OF MANUFACTURING DRY SORBENTS FOR HIGH-TEMPERATURE CARBON DIOXIDE CAPTURE BASED LITHIUM SILICATE AND DRY SORBENTS FOR HIGH-TEMPERATURE CARBON DIOXIDE CAPTURE

摘要

The present invention relates to a method for preparing a lithium silicate-based dry absorbent for high-temperature use and a dry-type dry absorbent for removing carbon dioxide, comprising the steps of: mixing a lithium precursor, silicon oxide and a metal oxide to form a mixed material; And calcining the resulting lithium silicate solids.
