WebSep 30, 2024 · At the heart of this catalytic reforming process is a specialized, precious-metal catalyst. This presentation explores the fundamentals of the catalytic reforming … Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline. The process converts low-octane linear … See more In the 1940s, Vladimir Haensel, a research chemist working for Universal Oil Products (UOP), developed a catalytic reforming process using a catalyst containing platinum. Haensel's process was subsequently … See more The most commonly used type of catalytic reforming unit has three reactors, each with a fixed bed of catalyst, and all of the catalyst is regenerated in situ during routine catalyst regeneration shutdowns which occur approximately once each 6 to 24 months. Such a … See more The sensitivity of catalytic reforming to contamination by sulfur and nitrogen requires hydrotreating the naphtha before it enters the reformer, adding to the cost and complexity of the process. Dehydrogenation, an important component of reforming, is a … See more • Oil Refinery Processes, A Brief Overview • Colorado School of Mines, Lecture Notes (Chapter 10, Refining Processes, Catalytic Refinery by John … See more Before describing the reaction chemistry of the catalytic reforming process as used in petroleum refineries, the typical naphthas used as … See more Most catalytic reforming catalysts contain platinum or rhenium on a silica or silica-alumina support base, and some contain both platinum and rhenium. Fresh catalyst is chlorided (chlorinated) prior to use. The noble metals (platinum and rhenium) are considered to be … See more Catalytic reformation is profitable in that it converts long-chain hydrocarbons, for which there is limited demand despite high supply, into short-chained hydrocarbons, which, due to their uses in petrol fuel, are in much greater demand. It can also be used to improve the … See more

Catalytic reforming - Wikipedia

Webreforming individual hydrocarbons and whole naphtha. n-Heptane was reformed at pressures from 150 to 450 psig., and n-hexane, methylcyclopentane, benzene, methylcyclohexane, and toluene were reformed at 300 psig. The rate of cyclization of. n-paraffins increases fourfold when the number of carbon atoms increase from six to seven. WebApr 9, 2013 · In the reforming complex, a feed pre-treater removes sulfur from the reformer feed using hydrogen and a desulfurization catalyst. The pre-treated feed then is sent to the reformer reactor where a catalyst and heat are used to restructure or reform low octane naphtha into higher octane hydrocarbon molecules that are valuable gasoline blending ...
