A process for the production of gasoline from a C4-fuel gas containing ethene and propene and catalytic reformate containing C6 to C8 aromatic hydrocarbons. The C4-fuel gas in stream (28) is obtained by catalytic cracking of the vacuum gas oil fraction (7) obtained by distillation of a crude feed (1) in a distillation apparatus (2). The reformate C6-C8 aromatic hydrocarbons in stream (15) is obtained by hydrotreating naphta (5) in zone (9), followed by reforming in zone (13). The C4-fuel gas (28) and C6-C8 aromatic reformate (15) are mixed and contacted in a catalytic reactor (29) with a zeolite catalyst to convert ethene and propene in the fuel gas to C5+ aliphatic and aromatic …

Why it's free to use
- Filed March 19, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
