| 20120027662 | INDUCTION HEATED GASIFIER - A method of removing organic components from a mixture containing organic and inorganic components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor primarily from the center of the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the organic components in the mixture to separate from the mixture as a vapor. The oxygen concentration in the induction heated screw conveyor is controlled so as to gasify the organic components. The gasified organic components are removed and the remaining inorganic components are collected. | 02-02-2012 |
| 20120024687 | INDUCTION HEATED SCREW - A method of separating a high boiling component from a mixture containing organic and/or inorganic boiling components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the boiling component(s) to separate from the mixture as a vapor and the boiling component is removed from the induction heated screw conveyor. | 02-02-2012 |
| 20110294922 | ENCAPSULATION OF PHOSPHORUS PENTASULFIDE - A method of treating or encapsulating phosphorus pentasulfide so that it can be safely handled, stored and transported. The treating or encapsulating involves combining the phosphorus pentasulfide with a hydrocarbon oil under high shearing conditions. The hydrocarbon oil can be a mineral oil such as a paraffinic oil. The encapsulated phosphorus pentasulfide is pumpable and, according to one embodiment, is used as a modifier/crosslinking agent in asphalt mixtures. | 12-01-2011 |
| 20110046273 | METHOD FOR PREPARING SILICON-SULFUR COMPOUNDS AND THEIR USE IN BITIMINOUS COMPOSITIONS - A method of producing sulfur modified organosilane compounds that can be used in asphalt binders which method involves: combining together an organosilane or mixtures of organosilanes, a sulfide, a halogen acceptor and solvent to form a reaction mixture; and allowing the organosilane to react with the sulfide in the presence of a halogen acceptor to produce a sulfur modified organosilane compound. The sulfur modified organosilane compound can be introduced into a polymer modified or unmodified asphalt binder in which the sulfur modified organosilane compound reacts with components in the asphalt mixture to form a modified asphalt. The organosilanes used to produce the sulfur modified organosilanes can be from a source of waste products (such as Direct Product Residue) in which case the waste products can be reused in asphalt binders. | 02-24-2011 |
| 20090270671 | Calcium-sodium polysulfide chemical reagent and production methods - A calcium-sodium polysulfide chemical reagent and methods for producing the reagent. The reagent is a blend of calcium polysulfide and sodium polysulfide that can be prepared using various types, sources and ratios of lime, elemental sulfur and sulfide ion using either virgin or waste materials. The reagent is amenable to inexpensive and high rate production methods at ambient or warmer temperatures. The reagent can be used to precipitate metals from wastewater, stabilize hexavalent chrome in hazardous waste residues, remove mercury from coal fired power plants, and as an electrolyte in large-scale bromide/polysulfide electrical storage batteries | 10-29-2009 |
