Abstract
The present invention relates to the processing of hydrocarbon-containing feedstreams in the presence of an interstitial metal hydride comprised of at least one chemical element selected from Groups 3-11 (including the lanthanides, atomic numbers 58 to 71), and at least one chemical element selected from Groups 13-15 from the IUPAC Periodic Table of Elements. These interstitial metal hydrides, their catalysts and processes using these interstitial metal hydrides and catalysts of the present invention improve overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams.

A process comprising the steps of:
- a) contacting a hydrocarbon feedstream with a catalyst comprised of an interstitial metal hydride in the presence of hydrogen at process reaction conditions of at least 150° C. and at least 200 psig;
- and
- b) obtaining an upgraded reaction product stream;
- wherein the interstitial metal hydride is comprised of at least a first chemical element selected from Groups 3-11 (including the lanthanides, atomic numbers 58 to 71), and at least a second chemical element selected from Groups 13-15 of the IUPAC Periodic Table of Elements.
