The invention provides a process for producing a hydrocarbon, which process comprises contacting an organic compound comprising at least one heteroatom with hydrogen in the presence of a solid catalyst, which catalyst comprises: (a) a metal which is palladium, platinum, rhodium, iridium, ruthenium, silver, gold, nickel or copper; and (b) a compound comprising: (i) niobium, tantalum, molybdenum or tungsten; and (ii) oxygen. Further provided is a composition, and a catalyst. Both the compositionand the catalyst comprise (a) a metal which is palladium, platinum, rhodium, iridium, ruthenium, silver, gold, nickel or copper; and (b) a compound comprising: (i) niobium, tantalum, molybdenum or tungsten;and (ii) oxygen. The catalyst is typically a hydrogenolysis catalyst. Itmay for instance be employed as a hydrodeoxygenation (HDO), hydrodesulfurization (HDS) or hydrodenitrogenation(HDN) catalyst, and is usually employed as an HDO catalyst. |
