    Abstract: A catalyst composition and process for preparing such catalyst composition which can be useful in contacting a hydrocarbon-containing fluid which contains a highly unsaturated hydrocarbon such as 1,3-butadiene, in the presence of hydrogen, with such catalyst composition in a hydrogenation zone under a hydrogenation condition effective to hydrogenate such highly unsaturated hydrocarbon to a less unsaturated hydrocarbon such as n-butene is disclosed. Such process for preparing a catalyst composition includes (1) combining a zeolite, a Group VIB metal, and an inorganic support to form a modified zeolite; (2) calcining such modified zeolite under a calcining condition to produce a calcined, modified zeolite; and (3) contacting such calcined, modified zeolite with a carburizing agent under a carburizing condition to provide such catalyst composition.

    Abstract: The present disclosure provides processes to convert heavy hydrocarbons to light distillates. The present disclosure further provides compositions including light distillates. In an embodiment, a process for upgrading a hydrocarbon feed includes dehydrogenating a C 3 -C 50 cyclic alkane and an C 2 -C 50 acyclic alkane in the presence of a dehydrogenation catalyst to form a C 3 -C 50 cyclic olefin and a C 2 -C 50 acyclic olefin. The process includes reacting the C 3 -C 50 cyclic olefin and the C 2 -C 50 acyclic olefin in the presence of a group 6 or group 8 transition metal catalysts to form a C 5 -C 200 olefin. The process further includes hydrogenating the C 5 -C 200 olefin in the presence of a hydrogenation catalyst to form a C 5 -C 200 hydrogenated product. Processes of the present disclosure may further include hydroisomerizing the C 5 -C 200 hydrogenated product in the presence of a hydroisomerization catalyst to form a C 5 -C 200 hydroisomerized product.
