20140316173 | PROCESS FOR PRODUCING JET FUEL FROM A HYDROCARBON SYNTHESIS PRODUCT STREAM - A process for producing jet fuel comprising the following steps:
| 10-23-2014 |
20140053459 | COLD FLOW RESPONSE OF DIESEL FUELS - The invention provides a blend of FT derived diesel, crude derived diesel, and CFPP improving additive, wherein the FT diesel is from 1 vol % to 50 vol % of the blend, said blend having a CFPP of below −18° C. The invention extends to use of FT diesel as a blend component for a compression ignition fuel blend, said blend including the FT diesel, a crude derived diesel fuel and a CFPP improver additive, wherein the FT diesel is from 1 vol % to 50 vol % of the blend, which blend has a CFPP of below −20° C. | 02-27-2014 |
20130333651 | DIESEL ENGINE EFFICIENCY IMPROVEMENT - The invention provides a method of operating a diesel engine under oxygen-limited conditions such that the efficiency of the engine is at least 1% improved over the engine efficiency obtained when using a conventional crude-derived diesel fuel, said method including the combustion of a distillate fuel having a density of below 0.800 g.cm | 12-19-2013 |
20130125849 | DIESEL ENGINE INJECTOR FOULING IMPROVEMENTS WITH A HIGHLY PARAFFINIC DISTILLATE FUEL - The invention provides the use of a highly paraffinic distillate fuel in a diesel fuel composition for reducing the formation of injector nozzle deposits when combusted in a diesel engine having a high pressure fuel injection system, wherein the distillate fuel has an aromatics content less than 0.1 wt %, a sulphur content less than 10 ppm and a paraffinic content of at least 70 wt %, such that the diesel fuel composition has a relative fouling behaviour of 70% or less and a density of more than 0.815 g.cm | 05-23-2013 |
20120209037 | FULLY SYNTHETIC JET FUEL - A fully synthetic aviation fuel or aviation fuel component is provided, having a total naphthenic content of more than 30 mass %, a mass ratio of naphthenic to iso-paraffinic hydrocarbon species of more than 1 and less than 15, a density (at 15° C.) of greater than 0.775 g·cm | 08-16-2012 |
20110100313 | REDUCTION OF WEAR IN COMPRESSION IGNITION ENGINE - The invention relates to a method of operating a compression ignition engine. According to the invention, the engine is operated with a Fischer-Tropsch derived fuel containing composition to reduce wearing of the engine cylinder walls compared to operating the engine with petroleum derived fuel. | 05-05-2011 |
20110024282 | METHOD AND APPARATUS FOR SEPARATING A MULTI-COMPONENT STREAM - A process vessel is provided for separating a multi-component stream. The process vessel includes an inlet for permitting introduction of reaction water stream into the vessel and an outlet for withdrawing a water-rich phase from the vessel. The vessel further includes a plurality of draw-off points for drawing off a phase rich in suspended hydrocarbons from the vessel, the draw-off point(s) being located above the outlet. | 02-03-2011 |
20100108568 | FISCHER-TROPSCH JET FUEL PROCESS - The invention provides a Fischer-Tropsch jet fuel refining process which has a jet fuel yield in excess of 60% by mass, said process including at least four of the following five conversion processes: a. hydrocracking one or more of a FT kerosene and heavier material fraction and a C9 and heavier FT syncrude fraction; b. oligomerising an FT syncrude fraction including hydrocarbons in the range C2 to C8; c. hydrotreating one or more of an FT syncrude fraction, a product from process b., and an alkylated FT syncrude fraction; d. aromatizing one or more of an FT syncrude fraction including hydrocarbons in the range C2 to C8, a product from process a., a product from process b, a product from process c., and a product from an aromatic alkylation process; and e. alkylating one or more of an FT syncrude fraction including hydrocarbons in the C2 to C6 range, a product from process b., and a product from process d. | 05-06-2010 |
20100093101 | METHOD FOR DETERMINING THE CONTENT OF METALLIC ELEMENTS IN FISCHER-TROPSCH WAXES - The invention provides a method for determining the content of metallic elements in Fischer-Tropsch waxes by Inductively Coupled Plasma (ICP), wherein digestion of one or more samples of the waxes is carried out in an open vessel microwave digestion system. The invention further provides a sampling protocol for use with the method. | 04-15-2010 |
20080200744 | TRIMERISATION AND OLIGOMERISATION OF OLEFINS USING A CHROMIUM BASED CATALYST - The invention provides a mixed heteroatomic ligand for an oligomerisation of olefins catalyst, which ligand includes at least three heteroatoms, of which at least one heteroatom is sulfur and at least two heteroatoms are not the same. The invention also provides a multidentate mixed heteroatomic ligand for an oligomerisation of olefins catalyst, which ligand includes at least three heteroatoms of which at least one is a sulfur atom. The ligand may also contain, in addition to sulfur, at least one nitrogen or phosphorous heteroatom. | 08-21-2008 |
