    Abstract: The present invention addresses to a catalyst, and the method for obtaining the same, for generating hydrogen and/or syngas. More specifically, the present invention describes a catalyst based on nickel, molybdenum and tungsten, for steam reforming processes of natural gas or other hydrocarbon streams (refinery gas, propane, butane, naphtha or any mixture thereof) that presents high resistance to deactivation by coke deposition. According to the present invention, the catalyst has NiMoW as its active phase, in bulk form and/or supported on an alumina oxide and other high surface area oxide supports, and may also contain other promoters. Furthermore, the present invention teaches the production of a catalyst whose active phase of NiMoW has high activity for hydrocarbon steam reforming reaction.
