  • CATALYST FOR THE GENERATION OF HYDROGEN AND/OR SYNTHESIS GAS, METHOD FOR OBTAINING SAME AND USE IN A STEAM REFORMING PROCESS
    Publication number: 20230158479
    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.

  • Process for pre-reforming hydrocarbon streams containing olefins, pre-reforming catalyst and a process for preparing said catalyst
    Patent number: 9637381
    Abstract: The present invention relates to a catalyst for steam pre-reforming of hydrocarbons, containing in its formulation nickel and rare earths supported on alumina or magnesium or calcium aluminates, so as to increase the resistance to coke deposition, and the process for preparing said catalyst. Additionally the present invention relates to a process for manufacturing hydrogen or syn gas through steam pre-reforming olefin-containing hydrocarbons in the presence of the catalyst obtained according to the present invention.

  • CATALYST FOR THE PRODUCTION OF SYNTHESIS GAS AND PROCESS FOR OBTAINING IT
    Publication number: 20160236183
    Abstract: This invention is aimed at making viable a catalyst and the process for obtaining it that besides having a higher resistance to the deposition of coke on the catalyst surface, does not introduce limitations to the process variables, maintains acceptable levels of activity throughout the steam reforming process and has a lower cost of production. The aforementioned objective is achieved by means of a catalyst formed by an inorganic oxide support, a mixture of Nickel, Lanthanum and Cerium and a promoter element.
