摘要： A catalyst composition is prepared by a method comprising impregnating alumina with at least one dissolved titanium compound (preferably a triethanolamine titanate) and at least one platinum compound, followed by treatment (at specific temperature conditions) with at least one organoaluminum chloride (preferably ethylaluminum dichloride), hydrogen chloride and at least one chloroalkane (preferably carbon tetrachloride).

摘要： 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.

摘要： In a process wherein hydrogen sulfide is converted to elemental sulfur in the presence of oxygen, an improvement is made by employing an alcoholic solution of an alkali metal hydroxide, free of iron-group salts or other heterogeneous catalysts. High yields of pure sulfur are obtained from such reactions begun at room temperature, without a requirement for heterogeneous catalysts or troublesome intermediates such as sulfur dioxide.
