| 205554000 | Sulfur containing compound produced | 6 |
| 20090020436 | HYDROGEN GENERATION PROCESS WITH DUAL PRESSURE MULTI STAGE ELECTROLYSIS - A multi-pressure hybrid sulfur process ( | 01-22-2009 |
| 20090078582 | APPARATUS FOR ELECTROLYZING SULFURIC ACID, METHOD OF PERFORMING ELECTROLYSIS, AND APPARATUS FOR PROCESSING A SUBSTRATE - An apparatus for electrolyzing sulfuric acid, the apparatus comprising an electrolytic cell comprising a cathode chamber having a cathode and an anode chamber having an anode, the cathode chamber and the anode chamber being separated by a diaphragm, a sulfuric acid tank configured to store the sulfuric acid, a supply pipe connecting the sulfuric acid tank to an inlet port of the anode chamber, a connection pipe connecting an outlet port of the cathode chamber to the inlet port of the anode chamber, a first supply pump provided on the supply pipe and configured to supply the sulfuric acid from the sulfuric acid tank to the cathode chamber through the supply pipe, and a drain pipe connected to an outlet port of the anode chamber and configured to supply to a solution tank a solution containing an oxidizing agent generated by electrolysis in the anode chamber. | 03-26-2009 |
| 20100089762 | Apparatus and Method For Reducing an Alkali Metal Electrochemically at a Temperature Below the Metal's Melting Temperature - A cell having an anode compartment and a cathode compartment is used to electrolyze an alkali metal polysulfide into an alkali metal. The cell includes an anode, wherein at least part of the anode is housed in the anode compartment. The cell also includes a quantity of anolyte housed within the anode compartment, the anolyte comprising an alkali metal polysulfide and a solvent. The cell includes a cathode, wherein at least part of the cathode is housed in the cathode compartment. A quantity of catholyte is housed within the cathode compartment. The cell operates at a temperature below the melting temperature of the alkali metal. | 04-15-2010 |
| 20110233068 | Ethylene Oxide Abator - Absorption of ethylene oxide is one of the methods commonly used to reduce air emissions from sterilization operations. Unlike prior art abators, the present method provides a means to regenerate the absorption medium within the abator and thus avoid the need to remove spent medium and load new medium every time the medium substantially consumed by the absorption process. Regeneration of the absorption medium is achieved through aqueous wash and air dry under ambient conditions and the regeneration cycle can be timed or automated as a function of medium consumption and regeneration of the liquid medium is achieved through electrochemical oxidation of the ethylene oxide reaction products. | 09-29-2011 |
| 20130334059 | APPARATUS FOR ELECTROLYZING SULFURIC ACID AND METHOD FOR ELECTROLYZING SULFURIC ACID - The present invention relates to an apparatus to produce oxidizing agent-rich sulfuric acid by electrolysis of sulfuric acid. More specifically, it relates to the apparatus by which dilute sulfuric acid of the specified temperature and concentration is formed within the electrolysis system and then, by electrolysis of the formed dilute sulfuric acid, electrolytic sulfuric acid containing richly oxidizing agent is formed at a high efficiency and safely under the temperature control. | 12-19-2013 |
| 20140042034 | HYBRID SULFUR CYCLE OPERATION FOR HIGH-TEMPERATURE GAS-COOLED REACTORS - A hybrid sulfur (HyS) cycle process for the production of hydrogen is provided. The process uses a proton exchange membrane (PEM) SO | 02-13-2014 |
