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, wi th a bifunctional catalyst containing a hydrogenating metal component in addition to a molecular sieve and a carrier for the simultaneou s removal of aromatics and isomerization of paraffins. The molecular sieve is preferably an aluminosilicate, or a silicoaluminophosphat e, the catalyst comprising as the hydrogenating/dehydrogenating component a metal from the group VI or VIII of the periodic table of the elements.
