FIELD: petroleum processing and petrochemistry.
SUBSTANCE: straight-run gasoline fractions are subjected to preliminary dehydration followed by reforming of resulting product in a system consisting of several in series arranged reactors. Dehydration and reforming operations are conducted on industrial Pt-eryonite catalyst (SG-3P) pretreated for 10-12 h with nitrogen at 100-130°C and then with hydrogen or hydrogen-containing gas while gradually raising temperature from 120°C to 480°C for 12 h and subsequent ageing at 480°C during 2-4 h. Dehydration temperature is 410-450°C and temperature of reforming in all reforming reactors is 475-490°C.
EFFECT: increased yield and octane number of reforming product.
