Document Type and Number:
WIPO Patent Application WO/2023/210876
Kind Code:
A1
Abstract:
The present invention relates to a system for capturing and recycling carbon dioxide and producing hydrogen for a cement manufacturing facility. An embodiment of the present invention is characterized by comprising: a preheater that has a plurality of stages of cyclones arranged in series in a vertical direction and receives and preheats a cement raw material; a calciner that calcines the cement raw material preheated by the preheater; a kiln that fires the cement raw material calcined in the calciner; an exhaust line, connected to the cyclones of the preheater, that discharges exhaust gas discharged from each of the calciner and the kiln to the outside; a reactor, disposed on the exhaust line, that receives the exhaust gas and reacts the exhaust gas with a basic alkali mixed solution to capture carbon dioxide in the exhaust gas, collect a reactant including the captured carbon dioxide, and separate a carbon dioxide reactant and a waste solution from the reactant; and a hydrogen generator that generates hydrogen gas by receiving the carbon dioxide reactant separated from the reactor.
