Reforming of naphtha
WebMost naphthenes react rapidly and efficiently to form aromatics. This is the basic reaction of reforming. Paraffins are the most difficult compounds to convert. A rich naphtha (lower paraffin, higher naphthene content) makes the operation much easier and more efficient.

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 hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes, which ar… WebThe most efficient use of reforming requires a thorough knowledge of changes in molecular composition over a range of operating conditions. Such knowledge has been gained for hydrocarbons containing up to ten carbon atoms by reforming individual hydrocarbons and whole naphtha. n-Heptane was reformed at pressures from 150 to 450 psig., and n ...
WebCatalytic reforming is a process used to convert low-octane naphthas into high-octane gasoline blending components called reformates. Reforming is the total effect of several … WebThe steam reforming of naphtha is, in essence, the reverse of the Fischer-Tropsch reaction, and is carried out under very similar conditions to methane reforming. [Pg.368] The process for steam reforming of naphtha was developed mainly by ICI in England and has been widely used in Europe, Japan, and many developing countries.
WebJan 1, 2014 · The heaviness (distillation endpoint) and type (lean or rich) are indicators of the difficulty in reforming the naphtha. For example, light-lean naphtha with an endpoint of 320 °F (160 °C) and 65 wt.% paraffins is more difficult to reform than a heavy-rich naphtha with an endpoint of 370 °F (188 °C) and 60 wt.% naphthenes plus aromatics.

This is done in a naphtha hydrotreater that may be considered part of the reformer, or a separate process unit. Next, the feed is sent through a series of 3-4 reactor vessels. arti daerah istimewaWebNaphtha reforming catalyst is a bifunctional catalyst consists of a metal function, mainly platinum, and an acid function, usually chloride alumina. The metal function catalyzes the hydrogenation and dehydrogenation reactions and the acid function promote the isomerization and cyclization reactions [11], [12], [13]. banco general panama tarifario
