WitrynaNaphtha is produced as a by-product of the BTL-FT process, both straight-run from the FT reactor and as a co-product of the upgrading of the FT wax to middle distillates. BTL-FT naphtha has a low octane number and cannot be used as a gasoline blending component. The two dominant processes that have been considered for upgrading … The first unit operation (after being desalinated) in a petroleum refinery is the crude oil distillation unit. The overhead liquid distillate from that unit is called virgin or straight-run naphtha and that distillate is the largest source of naphtha in most petroleum refineries. The naphtha is a mixture of many different hydrocarbon compounds. It has an initial boiling point (IBP) of about 35 °C and a final boiling point (FBP) of about 200 °C, and it contains paraffins, naphthenes (cyclic paraffins) and aromatic …
Witryna1 gru 2024 · Naphtha is transformed into reformates through catalytic reforming process which requires the reconstruction of low-octane hydrocarbons in the petroleum naphtha into more valuable high octane gasoline components.
