| 20090053596 | Alkali Metal Battery - A storage battery is provided comprising appositive electrode of lead, a negative electrode of mercury, and an electrolyte consisting of an aqueous solution of a salt of an alkali metal. Upon charging the battery, lead is converted to lead dioxide and the alkali metal forms the amalgam with the mercury. During discharge, the lead dioxide is reduced to the plumbous state and the alkali metal is oxidized to the positive ion and goes into solution. The mercury is immobilized in one of several alternative ways. | 02-26-2009 |
| 20090306437 | METHANOL SYNTHESIS - A process is disclosed for the synthesis of methanol from methane comprising three reaction steps operated in tandem. In the first step methylene chloride is produced by the reaction of methane with oxygen and hydrogen chloride. In the second step, methylene chloride is hydrolyzed to formaldehyde, which is hydrogenated in the third step to provide the product methanol. | 12-10-2009 |
| 20090312592 | Swing Reactor and Process for Oxychlorination - A reactor with swing feeds is provided for oxychlorination. This reactor comprises multiple inlets with controls capable of introducing feed streams sequentially to the reactor. In one configuration, a feed stream comprises a paraffin hydrocarbon, and a second feed stream comprises oxygen and hydrogen chloride. By segregating these feeds, combustion reactions can be minimized and yields of chlorinated paraffins increased. | 12-17-2009 |
| 20100047697 | LEAD-ZINC BATTERY - A rechargeable battery is provided such that the positive electrode companies lead, the negative electrode zinc, and the electrolyte is an aqueous solution of an alkali metal sulphate. Upon discharge, lead dioxide is reduced to lead sulphate and zinc is oxidized to zinc oxide. The reactions are reversed when the battery is charged. | 02-25-2010 |
| 20100087691 | Swing Reactor and Process for Oxychlorination - A reactor with swing feeds is provided for oxychlorination. This reactor comprises multiple inlets with controls capable of introducing feed streams sequentially to the reactor. In one configuration, a feed stream comprises a paraffin or olefin hydrocarbon such as methane or ethylene, and a second feed stream comprises oxygen and hydrogen chloride. By segregating these feeds, combustion reactions can be minimized and yields of chlorinated components increased. | 04-08-2010 |
| 20100101980 | EXTRACTION OF BITUMEN FROM OIL SANDS - Carbon disulfide is used as a solvent to extract bitumen from oil sands in an anhydrous countercurrent flow process that is compatible with existing procedures for upgrading bitumen. The solution is then fractionated to separate the carbon disulfide from the bitumen product. The bitumen is then treated with hydrogen to decompose the remaining carbon disulfide. The process should provide high yields and meet environmental concerns. | 04-29-2010 |
| 20100261053 | LEAD-PALLADIUM BATTERY - A storage battery is provided comprising a positive electrode of lead, a negative electrode of palladium, and an electrolyte consisting of an aqueous solution of a sulfate salt. Upon charging, lead is converted to lead dioxide and atomic hydrogen is absorbed by the palladium. During discharge, lead dioxide is reduced to the plumbous state and hydrogen is oxidized to hydrogen ions. | 10-14-2010 |
| 20110105801 | FORMALDEHYDE SYNTHESIS - A process is disclosed for the synthesis of formaldehyde from methane starting with the oxychlorination of methane to produce methylene chloride. Hydrolysis of methylene chloride yields the product formaldehyde. Gaseous formaldehyde is condensed for shipment. Byproduct chloroform and carbon tetrachloride are recovered and hydrogenated to provide additional methylene chloride. | 05-05-2011 |
