| 20110301024 | PROCESS FOR THE PREPARATION OF FISCHER-TROPSCH CATALYSTS AND THEIR USE - A process for preparing a catalyst precursor includes, in a first preparation step, impregnating a particulate catalyst support with an organic metal compound in a carrier liquid. The metal of the organic metal compound is an active catalyst component. An impregnated intermediate is formed, and is calcined to obtain a calcined intermediate. Thereafter, in a second preparation step, the calcined intermediate from the first preparation step is impregnated with an inorganic metal salt in a carrier liquid. The metal of the inorganic metal salt is an active catalyst component. An impregnated support is obtained, and is calcined, to obtain the catalyst precursor. The metal is in particular cobalt. The precursor is reduced, in particular with hydrogen, to obtain the active catalyst. Also claimed is a process for the hydrogenation of CO, as well as a process for the hydrogenation of an organic compound using the so-prepared catalyst. | 12-08-2011 |
| 20110245355 | CATALYSTS - A process for regenerating a spent particulate wax-containing cobalt-based Fischer-Tropsch synthesis catalyst is provided. The process includes subjecting the spent wax-containing catalyst sequentially to a dewaxing treatment, an oxidation treatment and a reduction treatment. During the dewaxing treatment, the spent wax-containing catalyst is at least partially dewaxed, with dewaxed catalyst particles being produced. During the oxidation treatment, an oxygen-containing gas is passed through a bed of the dewaxed catalyst particles at an operating temperature T° C. where 150| 10-06-2011 | |

| 20100268006 | Process for Polymerising or Oligomerising a Hydrocarbon - A process for polymerising or oligomerising a hydrocarbon includes feeding a liquid hydrocarbon reactant and a liquid evaporative cooling medium into a bulk liquid phase which includes polymeric or oligomeric product admixed with a catalyst, and allowing at least a portion of the liquid hydrocarbon reactant and the liquid evaporative cooling medium to vapourise to form bubbles rising through the bulk liquid phase, with the hydrocarbon reactant polymerising or oligomerising to form the polymeric or oligomeric product and with the evaporation of both the liquid hydrocarbon reactant and the liquid evaporative cooling medium effecting heat removal from the bulk liquid phase. Gaseous components are withdrawn from a head space, cooled and separated. Condensed hydrocarbon reactant and condensed cooling medium are recycled to the bulk liquid phase. | 10-21-2010 |
| 20100249343 | Process for Polymerising or Oligomerising a Hydrocarbon - A process for polymerizing or oligomerising a hydrocarbon includes feeding at a low level a liquid hydrocarbon reactant into a bulk liquid phase comprising polymeric or oligomeric product admixed with a catalyst. The liquid hydrocarbon reactant is allowed to vapourise to form bubbles rising through the bulk liquid phase and to polymerise or oligomerise to form the polymeric or oligomeric product, with the rising bubbles creating turbulence in the bulk liquid phase, thereby mixing the bulk liquid phase. Gaseous components comprising any unreacted vapourised hydrocarbon reactant and any gaseous product that may have formed are withdrawn from a head space above the bulk liquid phase. Liquid phase from the bulk liquid phase is withdrawn to maintain the bulk liquid phase at a desired level. | 09-30-2010 |
