    摘要: Provided is a hydrogenation catalyst of carbon monoxide, which is suited to the manufacture of a hydrogenation product containing target components (e.g., gasoline fuel oil components or diesel fuel oil components) at high selectivity from a gas mixture of hydrogen and carbon monoxide. This hydrogenation catalyst of carbon monoxide has a structure in which a transition metal is carried by a porous material in which 90% or more of all pores are fine pores each having a diameter of 1 to 50 nm.

    摘要: A catalyst for purification of exhaust gas includes a carrier, and a catalyst layer containing an alkali metal and/or an alkaline earth metal as an NOx-adsorbing component, the catalyst layer being loaded on the carrier, in which catalyst the carrier-composing material contains Si in an amount of 0.5 to 10.0% by weight as expressed as an oxide. Since the inclusion of Si can suppress the deterioration of the carrier caused by the alkali metal and/or the alkaline earth metal during the use of the catalyst, the catalyst can be used over a long period.
