Platinum-palladium catalyst for selective hydrogenation of aromatics and olefins in hydrocarbon fractions US4309277A (en) * 1979-05-04:1982-01-05:Uop Inc. Conversion of hydrocarbons with a
May 05, 2021 · Platinum on chlorinated alumina isomerization catalysts are more active at a higher pressure and lower temperature , then cracking processes are minimizing, and the effect of coking on catalyst deactivation is low. It requires only a slight excess of stoichiometric hydrogen to have a very high yield of the product. Influence of preparation conditions on catalytic activity Sep 25, 2018 · Alumina-supported Pt particles are frequently used as catalysts for a number of processes, due to activity of platinum in the reactions of oxidation, hydrogenation, isomerization, etc. For example, the total oxidation of hydrocarbons over Pt/Al 2 O 3 , particularly, of methane, is of interest for many branches of industry.
Platinum in any form was virtually unused in the petroleum industry until 1949. Then Universal Oil Products Company introduced it on an unprecedented scale as the active catalytic agent in its Platforming process for catalytically upgrading low octane petroleum naphthas to high quality products. Preparation of Highly Active Alumina-Pillared Clay Apr 08, 2009 · Effect of Pt precursor and pretreatment on hydrodesulfurization (HDS) activity of Pt/Al-PILM catalyst was examined to prepare highly active Pt-supported HDS catalyst. The order of HDS activities of Pt/alumina-pillared clay montmorillonite (Al-PILM) catalysts prepared by various Pt precursors was Pt(C5H7O2)2 > H2PtCl6 · 6H2O > [Pt(NH3)4](NO3)2 > [Pt(NH3)4]Cl2 · H2O >
Platinum-tin on alumina catalysts appear to have potential for use during naphtha reforming in processes utilising continuous catalyst regeneration, and without the need for complex activation Alumina-supported platinum catalysts:Local atomic Sep 22, 2014 · 1. Introduction. Alumina-supported platinum (Pt/-Al 2 O 3) catalysts appear to be one of the most attractive catalysts in a variety of practically important processes such as oxidation of hydrocarbons , , gasoline reforming processes , CO oxidation , , etc. Dispersion, structure, oxidation state of the active component as well as metalsupport interaction are well known to impact
