Abstract: Proposed is a carbon dioxide reforming (CDR) reactor having a multilayered catalyst layer arrangement for preventing catalyst deactivation, wherein, in the reactor in which a CDR reaction for reacting methane (CH4) with carbon dioxide (CO2) to reform the methane into a synthesis gas including carbon monoxide (CO) and hydrogen (H2) is performed, in order to prevent a case where an endothermic reaction between a catalyst and heated reactant gas supplied to the reactor gradually causes the temperature of the reactant gas to decrease and the catalyst is deactivated by cokes generated due to the decrease in temperature of the reactant gas, CDR catalysts in the reactor are arranged in multiple layers in a multilayered structure to allow the reactant gas temperature that has decreased due to the endothermic reaction to be restored in spaces between the catalyst layers.

Abstract: The present invention relates to a monolith catalyst for carbon-dioxide/methane reforming and a method of manufacturing the same, and more particularly to a novel monolith catalyst for a reforming reaction having improved thermal durability, configured such that a sintering inhibiting layer is formed by coating the surface of a monolith support with at least one element selected from the group consisting of Group 2, 3, 6, 13, 15 and 16 elements among elements in Period 3 or higher and an active catalyst layer is formed on the sintering inhibiting layer, thereby preventing carbon deposition and catalyst deactivation due to deterioration even upon reaction at high temperatures.

Abstract: The present invention relates to a monolith catalyst for reforming reaction, and more particularly, to a thermally stable (i.e. thermal resistance-improved) monolith catalyst for reforming reaction having a novel construction such that any one of Group 1A to Group 5A metals are used as a barrier component in the existing catalyst particles to inhibit carbon deposition occurring during the reforming reaction in a process for formation of a reforming monolith catalyst while improving thermal durability as well as non-activation of the catalyst due to a degradation.
