ROTATING METHANE PYROLYSIS SOLAR REACTOR, AND METHOD FOR PRODUCING HYDROGEN AND CARBON BLACK USING SAME

Document Type and Number:

WIPO Patent Application WO/2021/096319

Kind Code:

A1

Abstract:

The present invention relates to a rotating methane pyrolysis solar reactor, and a method for producing hydrogen and/or carbon black using same. The rotating methane pyrolysis solar reactor, according to the present invention, is a rotating reactor which is centered around a shaft, rotatable by means of a motor, and in which has solar heat, concentrated by a solar concentrator, is vertically incident on the wall surface of the cylindrical reactor, the reactor comprising: a CH4 and H2O spraying unit for injecting CH4-containing gas and water into a gas-liquid atomizing nozzle of a steam injector; and a reaction unit having a porous reaction bed, in which a carbon particle fluid may flow through mutually connected pores, and decomposing CH4, provided from the spraying unit, into hydrogen gas and carbon black by means of concentrated solar heat, wherein steam provided from the CH4 and H2O spraying unit is heated by the concentrated solar heat in the reaction unit, and then coated on the porous reaction bed and dispersed in the carbon particle fluid, thereby inhibiting carbon deposition in the porous reaction bed.
