Abstract
The invention discloses a method for preparing lithium silicate material absorbing high-temperature CO2 by taking artificial zeolite as raw material, and provides a process for preparing lithium silicate material serving as high-temperature CO2 absorbent by use of artificial zeolite. Lithium silicate precursors are prepared from LiNO3 and artificial zeolite in different proportions by ion exchange and sol-gel methods, and the lithium silicate material is synthesized by roasting the lithium silicate precursors at a temperature between 600 and 900 DEG C for 2 to 8 hours. The lithium silicate material prepared absorbs CO2 in a thermogravimetric analyzer at a temperature between 400 and 700 DEG C in CO2 and N2 atmosphere in different proportions. Aiming at the problem of a great amount of high-temperature CO2 emitted from power plants and flue gas, the method recycles carbon resources and reduces CO2 emission. The method synthesizes the lithium silicate material by taking cheap artificial zeolite and LiNO3 as raw material and adopting the ion exchange and sol-gel methods. Compared with the prior art, the method has the advantages of cheap and readily available artificial zeolite used as the raw material, reduction in preparation cost of the lithium silicate material and easiness of realizing industrial production.
