Abstract: Process for isomerisation of a hydrocarbonaceous feedstock substantially boiling in the gasoline range which feedstock comprises linear paraffins having at least five carbon atoms wherein the feedstock is contacted in the presence of hydrogen at elevated temperature and pressure with a catalyst comprising in combination platinum (Pt) and palladium (Pd) each in metallic form supported on an acidic amorphous alumina or molecular sieve, and isomerised hydrocarbons preprared by the process.

Abstract: A process for producing a middle distillate suitable for example as a diesel fuel, with improved low temperature properties and a low content of aromatic compounds, from a hydrocarbon feed as the starting material by contacting the feed material in a single reaction step, in the presence of hydrogen, and at an elevated temperature and pressure, with a bifunctional catalyst containing a hydrogenating metal component in addition to a molecular sieve and a carrier for the simultaneous removal of aromatics and isomerization of paraffins. The molecular sieve is preferably an aluminosilicate, or a silicoaluminophosphate, the catalyst comprising as the hydrogenating/dehydrogenating component a metal from the group VI or VIII of the periodic table of the elements.
