ABSTRACT Olefins and aromatic compounds in mixed hydrocarbon streams boiling above about 200°F are hydrogenated at a tem- perature ranging between about 400°F-720°F using a zeolite- containing catalyst that has been treated with a hydrocarbon stream relatively high in organic nitrogen compounds to sup- press the cracking activity of the catalyst. The catalyst comprises (1) an amorphous base component, (2) a crystalline aluminosilicate component preferably comprising 5-30 wt. % of the total catalyst and having a silica/alumina mole ratio of at least 2.5 and an alkali metal content of less than about 2.0 wt. % and (3) a transition metal hydrogenation com- ponent. The process is particularly useful in the manufac- ture of jet fuels and technical white oils and white oil bases with a minimum conversion of feed ( < 20%) to substan- tailly lower boiling products.
