ABSTRACT:
Olefins and aromatic compounds in mixed hydrocarbon streams boiling above about 200.degree. F. are hydrogenated at a temperature ranging between about 400.degree. F.-720.degree. F. using a zeolite-containing catalyst that has been treated with a hydrocarbon stream relatively high in organic nitrogen compounds to suppress 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 component. The process is particularly useful in the manufacture of jet fuels and technical white oils and white oil bases with a minimum conversion of feed (<20%) to substantially lower boiling products.
