CARBON DIOXIDE REMOVAL SYSTEM

摘要

A process for capture of carbon dioxide from gases comprising using Li4SiO4 contained in a molten salt mixture at a elevated temperature and recovering the CO2 captured. Also disclosed is A process for producing hydrogen from hydrocarbons or coal comprising reacting steam and hydrocarbon at conditions that convert them to hydrogen and CO2; contacting the CO2 containing gas so formed with Li4SiO4 contained in a molten salt mixture at an elevated temperature and recovering the CO2 so captured.

1. A process for capture of carbon dioxide from gases comprising contacting a CO2 containing gas with Li4SiO4 contained in a molten salt mixture at a temperature of about 800-1200° F. and a Li4SiO4 content in the molten salt mixture of about 1-30% and recovering the CO2 captured by the Li4SiO4 by heating the salt to 1300° F.
