Process for producing diesel fuel of high calorific value.

It presents a procedure for producing a suitable middle distillate such as diesel fuel, with improved low temperature properties and a low content of aromatic compounds from a hydrocarbonaceous supply as starting material by contacting the material supply step single reaction in the presence of hydrogen and an elevated temperature and pressure with a bifunctional catalyst containing a component hydrogenating metal and a molecular sieve and a carrier for the simultaneous removal of aromatics and isomerization of paraffins. The molecular sieve is preferably a silicoaluminophosphate or aluminosilicate, the catalyst comprises as hydrogenating / dehydrogenating component a metal of group VI or VIII of the periodic table of elements.
