| 摘要 |
The invention provides a process for production of high-octane gasoline from a C6-C10 hydrocarbon feed stream by selective dehydrogenation of cycloparaffins without substantially affecting aromatics and paraffins present in the feed. It involves a catalyst comprising a Group VIII metal supported on a substantially non-acidic porous material with concentration of acidic sites lower than 1 .mu.mole/g. The catalyst in the selective dehydrogenation typically comprises palladium, platinum, rhodium, iridium or mixtures thereof in an amount of 0.1 wt% to 1.0 wt% supported on a carrier material selected from silica, alumina, zirconia, titania, or mixtures thereof, other oxides, carbons, carbides and nitrides. The process for the production of high-octane gasoline from a C6-C10 hydrocarbon feed can be a combination of a catalytic dehydrogenation step, a catalytic isomerisation step and one or more separation steps.
