  • 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.

  • 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.

  • Patent number: 9365785
    Abstract: The invention described herein proposes steam reforming processes in two stages, the first stage being passing a synthesis gas stream through a first catalyst bed comprising an alkali metal and/or iron titanate based catalyst, and a second stage comprising at least a second catalyst bed containing a refractory supported metal catalyst, preferably having NiO as the metal phase supported with barium hexa-aluminate.

  • Patent number: 8642004
    Abstract: Using the process described in the present invention, a gas is produced that is rich in methane and hydrogen and has a content of olefins below 1% v/v, which fully meets the necessary requirements for raw materials used for large-scale production of hydrogen or synthesis gas, in steam reforming units that already exist in a great many oil refineries and petrochemical units. Starting from ethanol, steam, nickel-based catalysts and the use of appropriate conditions of temperature, and H2O/ethanol and H2/ethanol molar ratios, the invention teaches the production of hydrogen and synthesis gas from biomass, stably for long periods without loss of catalyst performance over time, permitting its industrial application in new units or in existing units. As a solution for the production of ethanol, the present invention claims the replacement of the ZnO-based and hydrofining catalysts of the feed pre-treatment section, with nickel-based catalysts and process conditions in accordance with the present invention.
