What is continuous reforming extract oil?
Thread Content
Is the reformed raffinate oil the oil remaining after the separation of aromatics, consisting of C6–C8 compounds? Does it still have a high octane rating? Thank you
The catalytic reforming unit used for downstream aromatic extraction is designed to produce BTX aromatic feedstocks; the reforming raffinate is the light naphtha with a low aromatic content that remains after the aromatic components have been extracted from the reforming product. The octane number of reformed raffinate oil is slightly lower than that of straight-run gasoline, with a RON generally ranging between 60 and 65. It is usually used to produce solvent oils or as a feedstock for ethylene production, and rarely serves as a component in the formulation of automotive gasoline. Unless there is an excess of high-octane alkylated oil within the enterprise or another batch of reformed oil available for use in gasoline blending to boost octane levels, considering the use of some of the withdrawn oil as a component in vehicle gasoline blending is not feasible.
