  • Patent number: 9611154
    Abstract: A method for the utilization of reaction water formed during the synthesis of hydrocarbons from synthesis gas in a GTL process includes the cleaning of oxygenates while quenching of the synthesis gas at a temperature of more than 500° C. while in contact with a catalyst for steam conversion of oxygenates, and the degasification of the cleaned up reaction water. Cleaned up and degasified water is utilized for cooling synthesis gas to a temperature of lower than 400° C. and for water steam production. The invention ensures efficient treatment of reaction water with removal of oxygenates, the use of obtained treated water as boiler feed water, and for the production of water steam.

  • Patent number: 9399209
    Abstract: The catalyst may be used to obtain hydrogen or synthesis gas for chemical industry in processes of partial oxidation, steam reforming, and autothermal reforming of a hydrocarbon feed. The catalyst of oxidative conversion of gaseous hydrocarbons to form carbon monoxide and hydrogen contains platinum-group metals and an oxide composition and characterized in that the platinum-group metals include Pt, Pd, and Rh and the oxide composition is obtained from a mixture of a sol of Al, Si, and Zr hydroxides with particles of Ni, Mg and/or Ce oxides with a size of 5-30 nm, that were obtained by spray-pyrolysis of a solution of Ni, Mg and/or Ce salts.

  • Patent number: 9346039
    Abstract: The invention relates to a method for preparation of oxide-polymetallic catalysts containing platinum-group metals for steam-oxidative conversion to obtain carbon monoxide and hydrogen. The method comprises treatment of NiO and CO3O4 by solutions of Al, Ce, Zr nitrates and palladium (Pd(NH3)4Cl2), platinum (H2[PtCl6]·6H2O) and rhodium (H3[RhCl6]) compounds followed by drying, carbonization of the obtained material in a methane flow at 550° C., preparation of slurry from this material, pseudo-boehmite and tetraisopropoxysilane, filling foam nichrome pores with obtained material suspension, elimination of water at 80° C., calcinating during 3 hours in an atmosphere of argon at 1300° C., elimination of carbon by water vapors at 600° C. during 3 hours. The technical result is development of a highly efficient heterogeneous catalyst. 3 material claims, 7 tables, 4 examples.

  • Publication number: 20160136604
    Abstract: This disclosure is related to reactor for partial oxidation of hydrocarbonaceous feedstock. The reactor comprises outer shell with reaction products outlet device with at least one device for inlet of feedstock or feedstock components into the catalyst sleeve placed within the reactor with a gap between the outer shell filled with a catalyst and comprising means of product outlet from its lower part. This catalyst sleeve is furnished with a jacket in contact with at least a part of the cylindrical wall of the catalyst sleeve having open-end holes in the point of contact with jacket, and the reactor is equipped with a means of inlet of a cooling agent into the jacket that cools the catalyst sleeve. Technical result of claimed invention is reduction of catalyst sleeve wall temperature to 1000° C. or lower and reduction of catalyst sleeve material corrosion.
