Title:
HYDROGEN AND CARBON GENERATION SYSTEM USING METHANE PYROLYSIS BY MEANS OF FLUIDIZED BED INDIRECT HEAT EXCHANGE
Document Type and Number:
WIPO Patent Application WO/2023/054753
Kind Code:
A1
Abstract:
The present invention provides a hydrogen and carbon generation system using methane pyrolysis by means of fluidized bed indirect heat exchange, the system comprising: a combustor for generating carbon dioxide by oxy-circulating fluidized bed combustion of fuel; a methane flow path which is disposed inside the combustor and through which methane is supplied from the outside and circulates; a pyrolyzer communicating with the methane flow path and generating hydrogen and carbon by pyrolysis of methane supplied via the methane flow path by means of heat transferred from beads supplied from the combustor; a separator for separating hydrogen and carbon transferred from the pyrolyzer, generating at least some of the carbon into solid carbon, and supplying the rest of the carbon to the combustor; heat exchangers comprising a first heat exchanger, for exchanging heat between oxygen supplied from the outside and hydrogen supplied from the separator, and a second heat exchanger disposed so as to surround at least a part of the methane flow path and exchanging heat between methane and carbon dioxide supplied from the combustor; a carbon dioxide tank for storing the carbon dioxide which has been heat exchanged by the second heat exchanger; and blowers comprising an oxygen blower, for supplying the oxygen supplied via the first heat exchanger to the combustor, and a carbon dioxide blower for supplying at least some of the carbon dioxide supplied from the carbon dioxide tank to the combustor.
