Reforming naphtha
WebCatalytic Reforming Catalytic Reforming Catalytic reforming converts low-octane, straight-run naphtha fractions, particularly heavy naphtha that is rich in naphthenes, into a high-octane, low-sulfur reformate, which is a major … 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.

WebThe standard feed to a catalytic reforming unit (CRU) is hydrotreated straight-run naphtha (SRN), typically containing C6 through C11 paraffins, naphthenes and aromatics. Naphtha from different sources varies greatly in its ease of reforming. Most naphthenes react rapidly and efficiently to form aromatics. This is the basic reaction of reforming. WebSteam Methane Reforming, or SMR, processes feedstocks, ranging from natural gas to light naphtha, mixed with steam to produce a hydrogen-rich syngas effluent, with a typical H2/CO ratio of 3:1 to 5:1. SMR based plants are most commonly used to produce a hydrogen product or a combination of a hydrogen stream and another syngas product.
