Patent number: 9062257Abstract: A process for converting carbonaceous materials or light hydrocarbon gases into products comprising predominately C5+ hydrocarbons. The process converts the feedstock into synthesis gas comprising hydrogen and carbon monoxide and then uses the Fischer-Tropsch reaction to produce heavy hydrocarbons. A small excess of hydrogen is produced in the syngas generator or by water gas shift for use in product upgrading and for blending with Fischer-Tropsch tail gas for recycle back to syngas generation. A portion of the Fischer-Tropsch tail gas is used as fuel, thus purging combustible light gases and CO2 from the tail gas. Hydrogen rich purge gas is blended into the remaining tail gas resulting in a recycle stream that is returned to the syngas generator. The tail gas components are therefore efficiently used to produce more products.Type: GrantFiled: November 18, 2014Date of Patent: June 23, 2015Assignee: EMERGING FUELS TECHNOLOGY, INC.Inventors: Kenneth L. Agee, Kym B. Arcuri, Rafael L. Espinoza

Patent number: 7423187Abstract: A continuous process for the separate recovery of TNT and RDX from a mixture of TNT and RDX. The mixture is introduced into a first vessel wherein TNT is separated from the RDX by use of a solvent that is effective for dissolving TNT but not RDX. The TNT in solvent is passed to a separation stage wherein the solvent is recovered a recycled to the first vessel. A slurry of RDX and water are passed to a second vessel where the water is displaced with a desensitizing agent for desensitizing RDX.Type: GrantFiled: March 10, 2004Date of Patent: September 9, 2008Assignee: Gradient TechnologyInventors: Kym B.

Publication number: 20010051662Abstract: A system and method of operating a pre-reformer in a gas-to-liquids plant at minimum steam/carbon levels in order to reduce the C2+ content is provided that allows for the efficient production of synthesis gas to be used in producing liquid hydrocarbons preferably through a Fischer-Tropsch synthesis. The process and system involves providing steam, natural gas having greater than 3 percent C2+, and possibly hydrogen to a pre-reformer and converting a significant amount of the C2+ to methane and CO2 and then using a synthesis gas generator to prepare a synthesis gas feedstock with about a 2:1 H2:CO ratio and without undue soot formation. The synthesis gas is used in a Fischer-Tropsch synthesis unit to convert the synthesis gas to the heavier hydrocarbons. Water, light hydrocarbons, and portions of the tail gas may be recycled in different embodiments.Type: ApplicationFiled: February 12, 2001Publication date: December 13, 2001Inventors: Kym B.
