  • Preparation of iron compounds by hydrothermal conversion
    Patent number: 7217400
    Abstract: An apparatus and continuous process for the conversion of one solid iron compound to another solid iron compound in a heterogeneous suspension wherein the suspension is formed by dispersing a solid starting iron compound in a liquid that is continuously fed through one or more agitated conversion vessels under hydrothermal conditions and converted to a solid product iron compound having different physical, chemical, or structural properties from the solid starting iron compound.

  • Fischer-tropsch process using a fischer-tropsch catalyst and a zeolite-containing catalyst
    Patent number: 7157501
    Abstract: Fischer-Tropsch process for the conversion of carbon monoxide and hydrogen to C5+ hydrocarbon mixtures in which process use is made of Fischer-Tropsch catalyst particles and fluid catalytic cracking (FCC) catalyst particles. The FCC catalyst can be a fresh FCC catalyst, or an equilibrium catalysts (E-cat).

  • Method for performing a Fischer-Tropsch process using an iron-containing layered material
    Patent number: 6933324
    Abstract: A method for performing a Fischer-Tropsch process using as a catalyst (precursor) an iron-containing layered material selected from the group consisting of layered materials in which iron is present in the layered structure as divalent and/or trivalent metal (group 1), iron-doped layered materials (group 2), calcined iron-doped layered materials (group 3), and calcined layered materials in which iron is present in the layered structure as divalent metal (group 4). The term “layered material” includes anionic clays, layered hydroxy salts, cationic clays, and cationic layered materials.
