Abstract:
A vehicle includes an internal combustion engine (ICE) to provide motive power to the vehicle. The ICE includes a pressurizable tank defining a tank volume to contain a solution of a natural gas and a liquid fuel. The ICE has a refueling port in fluid communication with the tank volume to selectably interface with a refueling nozzle to receive the solution from the refueling nozzle. A fuel supply tube conveys the solution from the pressurizable tank to the ICE. A fuel injector is in fluid communication with the fuel supply tube and a combustion chamber of the ICE. In response to a level of the solution in the pressurizable tank, the fuel injector is to selectably inject a predetermined quantity of the solution or a predetermined quantity of a gaseous mixture into the ICE for combustion. The gaseous mixture includes a vapor and the natural gas evaporated from the solution.
Abstract:
A process for preparing a renewable biofuel consists of subjecting a bio-oil mixture to deoxygenation in a hydrotreater and then separating hydrocarbon fractions from the deoxygenated product to form the biofuel. The bio-oil mixture contains a bio-oil feedstream and a treated bio-oil feed. The treated bio-oil feed is a stream from which undesirable heavy materials and solid materials have been removed.
Abstract:
An extraction system is provided to extract ethanol from an ethanol-gasoline blend fuel. The extraction system may provide a settling vessel for a mixture of water and the ethanol-gasoline blend fuel. The settling vessel may include a main body and a settling valve. The main body forms a cavity for receiving the mixture through an aperture near the top portion of the main body. The settling valve may extend off the main body near a bottom portion thereof, wherein the settling valve may be adapted for controlling the flow of the mixture or portions thereof positioned within the settling vessel.
Abstract:
The present invention relates to a catalyst additive composition suitable for fluid cracking, riser cracking and fixed bed cracking with reduction in bottom and coke, wherein the aluminosilicate and silica-alumina is generated in situ from added clay and silica. The present invention is also directed towards the preparation of the said catalyst additive composition. The invention also discloses a process for cracking of heavy hydrocarbons using the said catalyst additive.
Abstract:
A system for generating electric power and for producing gasoline from methanol, comprises: a gasoline production apparatus containing a catalyst layer for synthesizing gasoline from methanol, heat generated by the synthesis increasing a temperature of the gasoline production apparatus; a cooling apparatus for cooling the gasoline production apparatus with coolant to vaporize the coolant; and a power generation apparatus for generating electric power using the coolant vapor produced by the cooling apparatus.
Abstract:
Processes for decomposing organic chloride in a hydrocarbon stream may comprise contacting a hydrocarbon stream with a dechlorination element in a dechlorination zone under dechlorination conditions to provide a dechlorinated hydrocarbon product, wherein the dechlorination element may comprise a metal or metal alloy having a high surface area configuration. Such a dechlorination element may be disposed within one or more distillation columns and/or within a separate dechlorination vessel.
Abstract:
Described are methods for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons in a single reactor. The method includes reacting a water soluble oxygenated hydrocarbon in the presence of a catalyst at a temperature, pressure, and weight hour space velocity for a time sufficient to produce a self-separating, three-phase product stream comprising a vapor phase, an organic phase, and an aqueous phase. A portion of the organic phase can be reacted to produce alkanes, alkenes, alcohols, and aromatics.
Abstract:
Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons to aromatics and gasonline range hydrocarbons where the oxygenated hydrocarbons are derived from biomass.
