Abstract: One exemplary embodiment of the present disclosure can be a catalyst for catalytic reforming of naphtha. More specifically, the present disclosure relates to a reforming catalyst for the catalytic reforming of gasoline-range hydrocarbons that results in increased aromatics production. The catalyst can have a noble metal including one or more of platinum, palladium, rhodium, ruthenium, osmium, and iridium, one or more alkaline earth metals, and a support.

Abstract: Processes for catalytic reforming in which a cracking inhibitor, such as an olefin, or a light olefin, is used to inhibit thermal cracking of larger hydrocarbons in non-reactive zones. The cracking inhibitor may be added at various positions through the processes, such as in the recycle gas stream, before a heater, before a stream is passed into a reforming zone, after an effluent stream is recovered from a reforming zone. A molar ratio of cracking inhibitor to hydrocarbons in stream may be between 0.01 and 0.2.

Abstract: One exemplary embodiment can be a process for selective hydrogenation of acetylenes and diolefins to olefins. The process can include contacting a feedstream having olefins, acetylenes and diolefins with a layered catalyst at reaction conditions. Thus, the process may include creating an output stream with a reduced amount of acetylenes and diolefins. Generally, the layered catalyst has an inner core including an inert material, an outer layer, including a metal oxide, bonded to the inner core, and a metal, which is an International Union of Pure and Applied Chemistry Group 8-10 metal, deposited on the outer layer. Usually, the layered catalyst has an accessibility index of about 3—about 500, a void space index about 0—about 1, or both an accessibility index of about 3—about 500 and a void space index of about 0—about 1.

Abstract: Catalyst systems and methods provide benefits in reducing the content of nitrogen oxides in a gaseous stream containing nitric oxide (NO), hydrocarbons, carbon monoxide (CO), and oxygen (O2). The catalyst system comprises an oxidation catalyst comprising a first metal supported on a first inorganic oxide for catalyzing the oxidation of NO to nitrogen dioxide (NO2), and a reduction catalyst comprising a second metal supported on a second inorganic oxide for catalyzing the reduction of NO2 to nitrogen (N2).

Abstract: A method of carbon monoxide (CO) removal comprises providing an oxidation catalyst comprising cobalt supported on an inorganic oxide. The method further comprises feeding a gaseous stream comprising CO, and oxygen (O2) to the catalyst system, and removing CO from the gaseous stream by oxidizing the CO to carbon dioxide (CO2) in the presence of the oxidation catalyst at a temperature between about 20 to about 200° C.
