A layered catalyst reactor system and process for hydrotreatment of hydrocarbon feedstocks. The layered catalyst system reactors comprise vertical bed layers including a demetallization catalyst layer, multiple layers of supported hydrotreating catalyst layer, and multiple alternating layers of supported hydrocracking catalysts and self-supported hydrotreating catalysts. The arrangement of the catalyst layers mitigates the risk of temperature run-aways, with improvements in hydrotreatment performance.

The present invention relates to a method of improving the corrosion resistance of a metal substrate surface using an oxygen reduction catalyst, which may improve the corrosion resistance of the metal substrate surface by coating the metal substrate surface with the oxygen reduction catalyst so that the metal substrate surface is changed to a passive state through the action of the oxygen reduction catalyst in an environment in which a stable oxide layer is not spontaneously formed on the metal substrate surface. The present invention has an advantage in that it can dramatically improve the corrosion resistance of the metal substrate under a corrosive environment by allowing a recoverable oxide layer to be formed on the metal substrate surface through the action of the oxygen reduction catalyst, applied to the surface, even in an environment in which an oxide layer is not spontaneously formed on the metal substrate.

The invention relates to a novel catalyst for hydrogenation for hydrogenating at least one of dicarboxylic acid or its acid anhydride. The catalyst for hydrogenation according to a first embodiment is obtained by supporting at least one of palladium or platinum, and cobalt on a carrier, and subjecting the resulting carrier to a reduction treatment at 400 K or higher. The catalyst for hydrogenation according to a second embodiment is obtained by supporting at least one of palladium or platinum, and molybdenum on a carrier, and subjecting the resulting carrier to a reduction treatment at 500 K or higher.

Aspects of the present application provides for enhanced catalytic materials, which can feature multiple functional and/or catalytic species, and methods of their formation. The materials can include catalytic nanoparticles (NPs) partially embedded within a supporting matrix. Treatment of the material, e.g., thermal, optical, microwave, plasma, and/or chemical treatment, can lead to the formation of functionally, e.g., catalytic or co-catalytic, relevant chemical and structural/morphological species or features at the NP-matrix, NP-pore, and matrix-pore interfaces. The treated material is characterized by enhanced properties, e.g., greater mechanical stability.

A process for production of ammonia includes: providing a reaction stream including carbon monoxide and hydrogen; passing the reaction stream and steam over a water gas shift catalyst in a catalytic shift reactor, forming a shifted gas mixture depleted in carbon monoxide and enriched in hydrogen; passing the shifted gas mixture with an oxygen-containing gas over a selective oxidation catalyst at ≧175° C., forming a selectively oxidized gas stream with a portion of the carbon monoxide converted to carbon dioxide; removing some of the carbon dioxide from the selectively oxidized gas stream in a carbon dioxide removal unit; passing the carbon dioxide depleted stream over a methanation catalyst in a methanator to form a methanated gas stream, optionally adjusting its hydrogen:nitrogen molar ratio to form an ammonia synthesis gas; and passing the ammonia synthesis gas over an ammonia synthesis catalyst in an ammonia converter to form ammonia.
