Title:
高オクタン価ガソリン、および水素化・異性化と分離とを組合わせることによるその製造方法
Document Type and Number:
Japanese Patent JP4817134
Kind Code:
B2
Abstract:
The invention provides a high octane number gasoline pool comprises at least 2% of di-branched paraffins containing 7 carbon atoms, and a process for producing this gasoline pool by hydro-isomerising a feed constituted by a C5 to C8 cut which comprises at least one hydro-isomerisation section and at least one separation section, in which the hydro-isomerisation section comprises at least one reactor. The separation section comprises at least one unit and produces at least two streams: a first stream which is rich in di- and tri-branched paraffins, and possibly in naphthenes and aromatic compounds which is sent to the gasoline pool; and in a first version of the process, a second stream is produced which is rich in straight-chain and mono-branched paraffins which is recycled to the inlet of the hydro-isomerisation section, while in a second version of the process, a second flux is produced which is rich in straight-chain paraffins which is recycled to the inlet of a first hydro-isomerisation section and a third stream is produced which is rich in mono-branched paraffins which is recycled to the inlet of a second hydro-isomerisation section.
