Abstract: A chromium-free catalyst for use in a fluidized bed reactor is described. The catalyst comprises 45-70 wt % Fe2O3, 5-15 wt % CuO, 20-35 wt % Al2O3, 10-20 wt % ZnO, and 1-15 wt % K2CO3. The catalyst has a Davison Index (DI %) of less than or equal to 15. A method for converting carbon monoxide (CO) into carbon-dioxide (CO2) using the catalyst is described. The method includes introducing H2O and CO into a fluidized bed reactor having an operating temperature between about 375° C. and about 450° C. and comprising the chromium free catalyst. The CO conversion is at least 60%.

Abstract: This invention is directed to novel mixed transition metal iron (II/III) catalysts for the extraction of oxygen from CO2 and the selective reaction with organic compounds.

Abstract: A composition may include a binder; a coalescing agent with the general formula of wherein Z is C1-C10, wherein X is —H and Y is ?O or X is ?O and Y is —H or —CH3, and wherein R1 and R2 are independently selectable and comprise a C1-C12 or derivative thereof; and a solvent. The composition may be used in products like a paint, a coating, an adhesive, an ink, a toner, a sealant, a stain, a glaze, a carpet backing, and a primer.

Abstract: The disclosure relates to zinc oxide-based sorbents, and processes for preparing and using them. The sorbents are preferably used to remove one or more reduced sulfur species from gas streams. The sorbents comprise an active zinc component, optionally in combination with one or more promoter components and/or one or more substantially inert components. The active zinc component is a two phase material, consisting essentially of a zinc oxide (ZnO) phase and a zinc aluminate (ZnAl2O4) phase. Each of the two phases is characterized by a relatively small crystallite size of typically less than about 500 Angstroms. Preferably the sorbents are prepared by converting a precursor mixture, comprising a precipitated zinc oxide precursor and a precipitated aluminum oxide precursor, to the two-phase, active zinc oxide containing component.

Abstract: Reduced sulfur gas species (e.g., H2S, COS and CS2) are removed from a gas stream by compositions wherein a zinc titanate ingredient is associated with a metal oxide-aluminate phase material in the same particle species. Nonlimiting examples of metal oxides comprising the compositions include magnesium oxide, zinc oxide, calcium oxide, nickel oxide, etc.

Abstract: Processes are disclosed for removing sulfur, including cyclic and polycyclic organic sulfur components such as thiophenes and benzothiophenes, from a hydrocarbon feedstock including fuels and fuel components. The feedstock is contacted with a regenerable sorbent material capable of selectively adsorbing the sulfur compounds present in the hydrocarbon feedstock in the absence of a hydrodesulfurization catalyst. In one embodiment, the sorbent can be an active metal oxide sulfur sorbent in combination with a refractory inorganic oxide cracking catalyst support. In another embodiment, the sorbent can be a metal-substituted refractory inorganic oxide cracking catalyst wherein the metal is a metal which is capable in its oxide form, of adsorption of reduced sulfur compounds by conversion of the metal oxide to a metal sulfide. The processes are preferably carried out in a transport bed reactor.
