International Classification:

B01J 2010

US Classification:

502232

Abstract:

Described is a method for preparing a catalyst support material, comprising commercially available silica, by utilizing a fluorine-containing acid. The novel method is utilized to produce a novel composition that has unique physical properties different from those of typical commercially available silica materials. The novel support material has significantly improved values for crush strength and as good or better pore volume than comparable catalyst support materials. Due to these improved physical properties, the novel composition is more durable and longer lived. Furthermore, the greater pore volume of the novel composition provides for enhanced catalytic activity when the formed silica material is utilized as a catalyst support.

International Classification:

B01J 27135

US Classification:

502227

Abstract:

This invention is a catalyst and a process using that catalyst for oxidizing hydrogen bromide to form elemental bromine. The inventive catalyst composition comprises cerium bromide on certain zirconia containing supports. The zirconia support, preferably largely in the baddeleyite phase, stabilizes the cerium bromide catalyst against cerium oxide formation at operating temperatures and gives the catalyst excellent activity at lower temperatures.

International Classification:

B01J 3706

US Classification:

502329

Abstract:

Impregnated chloride ions are removed from a chloride containing, platinum on zinc aluminate catalyst support in a specific sequence of operations. In the dechlorination steps, the impregnated platinum is first anchored to the zinc aluminate support in a calcining step, and then the calcined catalyst support is washed with a wash medium to remove the corrosive chloride without removing the platinum catalyst.
