Conversion of low octane number alkylate to high octane gasoline and aromatics
Patent
·
OSTI ID:5212871
An intentionally produced low octane value alkylate is reformed in the presence of steam, and in the absence of added hydrogen, to produce a high octane value, olefinic reformate containing aromatics. The reformate, upon fractionation to remove hydrogen and methane and C/sub 3/ and C/sub 4/ hydrocarbons, which can be recycled, is subjected to solvent extraction to produce a raffinate which can be used as high octane gasoline and which contains olefins, and an extract which, upon fractionation to remove xylenes therefrom as usable product, and which now contains benzene and toluene, can be combined with the raffinate.
