    摘要: This invention provides a process for forming elemental bromine. The process comprises bringing feeds of a gas comprising hydrogen bromide and a gas comprising molecular oxygen into contact with a catalyst comprising cerium oxide and/or cerium bromide on an inorganic oxide support. The process is characterized in that the catalyst contains cerium in an amount of about 25 wt% to about 75 wt%, expressed as cerium oxide, relative to the total weight of the catalyst, and that the feeds are at a temperature of about 200°C or below during process initiation, with the proviso that when the feeds are at a temperature of about 100°C or below, the feeds are anhydrous during process initiation.

    摘要: Processes and systems that include use of a packed wet oxidation reactor for oxidizing aqueous metal bromide salts in a bromine-based process for converting lower molecular weight alkanes to higher molecular weight hydrocarbons. A stream comprising a dissolved metal bromide salt may be oxidized in a wet oxidation reactor comprising a packed section to produce at least a partially oxidized liquid stream comprising oxidized products of the metal bromide salt and a gaseous bromine stream comprising elemental bromine.

    摘要: A method is provided for converting hydrogen bromide to elemental bromine. A portion of an initial hydrogen bromide-rich gas is thermally oxidized at a thermal oxidation temperature to produce a first fraction of elemental bromine and a remainder of the initial hydrogen bromide-rich gas. At least a portion of the remainder of the initial hydrogen bromide-rich gas is catalytically oxidized at a lower catalytic oxidation temperature to produce a second fraction of elemental bromine.
