20090247804 | METHODS FOR CONVERSION OF METHANE TO USEFUL HYDROCARBONS AND CATALYSTS FOR USE THEREIN - Methods are provided for converting methane to useful hydrocarbons. In the methods provided, a fluid comprising methane and hydrogen is combined with a catalyst composition derived from at least an aluminum compound, such as an aluminum halide, an aluminum alkyl, or a aluminum hydrate, and a second component such as a transition metal halide, a transition metal hydride, or a zero-valent metal, to produce heavier hydrocarbons. | 10-01-2009 |
20100015034 | PROCESSES FOR OXIDIZING HYDROGEN BROMIDE TO PRODUCE ELEMENTAL BROMINE - Processes are provided for catalytic oxidation of bromide to bromine by use of oxygen at temperatures of at least about 315° C. in the presence of a cerium-containing compound, such as a cerium bromide catalyst, wherein the produced stream comprising Br | 01-21-2010 |
20100030005 | PROCESSES FOR PRODUCING HIGHER HYDROCARBONS FROM METHANE AND BROMINE - Processes for producing C2+ hydrocarbons are provided. Such processes use Br2, HBr, and/or heat that are produced by such processes, thus providing commercially efficient processes. The process can comprise (a) producing HBr and methyl bromide using a bromine source and a gas stream comprising methane; (b) heating the methyl bromide in the presence of a catalyst to produce additional HBr and C2+ hydrocarbons; (c) combining at least some of the HBr and an oxygen source in the presence of a cerium-containing compound at least about 315° C. to produce Br2; and (d) using at least some of the produced Br2 from (c) as at least a portion of the bromine source in (a). Additionally, the additional HBr from (b) can be used in (c) and/or heat can be recovered from (c) and used to provide at least some of the heating in (a), (b), or both. | 02-04-2010 |
20100047155 | PROCESSES FOR CONJOINTLY PRODUCING BROMINE AND CALCIUM CHLORIDE - Processes are provided for conjointly producing Br2 and a concentrated aqueous solution containing at least about 5 wt % CaCI2, based on the weight of the concentrated aqueous solution, from an aqueous HBr rich stream and, optionally, a feed brine dilute in CaCI2. Such processes can comprise feeding the aqueous HBr-rich stream and the feed brine to a tower, oxidizing bromide moieties within the tower with Cl2 to produce Br2, recovering Br2 from the tower, removing a bromide-depleted bottoms from the tower, such bottoms containing HCI, adding a Ca++ source to the bromide-depleted bottoms to convert substantially all of the HCI in the bottoms to CaCI2, and, as necessary, removing water from the treated bottoms to produce the concentrated aqueous solution. | 02-25-2010 |
20100087308 | METHODS FOR CONVERSION OF METHANE TO USEFUL HYDROCARBONS, CATALYSTS FOR USE THEREIN, AND REGENERATION OF THE CATALYSTS - Methods are provided for regenerating catalyst compositions useful in processes for converting methane to useful hydrocarbons. The methods comprise applying voltage across the catalyst compositions. | 04-08-2010 |
