  • Publication number: 20230002691
    Abstract: The present invention relates to a catalyst to be applied to the process of gasification of coke or coal, individually or in mixture, and to the process of preparing said catalyst, which is useful in obtaining higher levels of hydrogen and carbon monoxide, which allows the conversion of coke into by-products of higher added value (hydrogen-rich syngas). The present invention also addresses to a process for converting petroleum coke by using a catalyst according to the present invention.

  • Publication number: 20070286781
    Abstract: A process to prepare multi-metal materials based on transition metals, using co-precipitation of mixed compound from solutions containing the metals, more specifically a process to prepare multi-metal materials based on transition metals, using co-precipitation, preferably seeking a condition of formation of a gel, from the mixture of precursor solutions containing the metals. The parameters of the process are set in such a way that the material is able to be molded by extrusion, obtaining extruded material with superior physico chemical properties, which may be used as an adsorbent, a catalyst or catalyst support, or even as filler in the reactor or column.

  • Publication number: 20070284289
    Abstract: A process to prepare new catalysts made from mixed metal oxides of transition metals, which involves the preparation of precursors and synthesis of these materials in oxide form from the preparation of a sol-gel formed from inorganic salts of these metals. An advance in the preparation of these catalysts made of mixed transition metal carbides and nitrides is proposed, providing an alternative way to the process of synthesis by solid-state reaction. The final product, in extruded form, has textural and mechanical properties superior to those obtained by the known techniques in the state of the art, and with better catalytic activity for hydrotreatment reactions.
