Abstract: The present invention relates to a method of directly preparing a dicarbamate compound from a diamine compound, and more particularly to a method of directly preparing a dicarbamate compound by reacting a diamine compound with an alcohol compound in the presence of a mixed gas of carbon monoxide (CO) and oxygen (O2) using a Pd/MOx catalyst configured such that a palladium (Pd) active metal is supported on a metal oxide or metalloid oxide carrier.

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.
