Abstract:
The present invention relates to a method for joint production of low octane gasoline and high octane gasoline. In the process of oil or light oil rectification, the extraction points of the distillates therein are finely divided, and the temperature ranges for extraction of fractions are narrowed down. Each of the low and high octane components having a high content in the range from C6-C12 (which may be extended to C5-C14 where necessary) is then separately extracted. After that, low octane components are combined into compression ignition low octane gasoline products, while high octane components are combined into high octane gasoline products. The remaining fractions are respectively added as supplementing agents into the low octane gasoline products or high octane gasoline products dependent on their octane ratings. Low octane gasoline is used in compression ignition gasoline engines, while high octane gasoline is used in spark ignition gasoline engines.

Methods of making fuel are described herein. A method may include providing a first working fluid, a second working fluid, and a third working fluid. The method may further include exposing the first working fluid to a first high-voltage electric field to produce a first plasma, exposing the second working fluid to a second high-voltage electric field to produce a second plasma, and exposing the third working fluid to a third high-voltage electric field to produce a third plasma. The method may also include contacting the third plasma, the second plasma, and the first plasma to form a plasma mixture, cooling the plasma mixture using a heat exchange device to form a cooled plasma mixture, and contacting the cooled plasma mixture with a catalyst to form a fuel fluid.
Abstract:
A method for upgrading fluid catalytic cracking gasoline includes the following steps: cutting fluid catalytic cracking gasoline into light, medium, and heavy gasoline fractions; subjecting the medium gasoline fraction to an aromatization/hydroisomerization reaction in the presence of a catalyst to obtain a desulfurized medium gasoline fraction; and blending the light gasoline fraction, the desulfurized medium gasoline fraction and the heavy gasoline fraction to obtain upgraded gasoline; where, a cutting temperature of the light and the medium gasoline fractions is 35-60° C., and a cutting temperature of the medium and the heavy gasoline fractions is 70-160° C. The method according to the present invention not only can realize deep desulfurization of fluid catalytic cracking gasoline, but also can improve octane number significantly.

Methods and systems for blending multiple batches of mixed hydrocarbons into fuel streams downstream of the refinery are provided that do not compromise the octane value of the fuel and do not cause the volatility of the fuel to exceed volatilities imposed by government regulation.
Abstract:
A process for converting ethane to liquid fuels may involve directing an ethane stream into an ethane cracking unit to produce an intermediate hydrocarbon stream and a raw ethylene stream; fractionating the intermediate hydrocarbon stream into a gasoline fraction and a diesel fraction; introducing the raw ethylene stream into an oligomerization unit; contacting the raw ethylene stream with an oligomerization catalyst to produce a liquid hydrocarbon stream and an off-gas stream; recycling an off-gas recycle stream from an off-gas stream of the oligomerization unit separation unit to an inlet of the oligomerization reactor; introducing at least part of the off-gas stream into a hydrogenation reactor to remove unconverted olefins; separating a hydrogen component and a plurality of light paraffin components in a post hydrogenation reactor separation unit using a PSA technology or membrane technology; and recycling the light paraffins stream into the ethane cracking unit.

Abstract:
A process and apparatus for controlling the amount of gasoline and distillate obtained from an oligomerate product is described. The process includes oligomerizing olefins in a feed stream to produce a mixture of an oligomerate product and unreacted feed. The mixture is separated into a light stream comprising the unreacted feed and the oligomerate product. Some or all of the oligomerate product is hydrogenated to produce hydrotreated oligomerate product. The hydrotreated oligomerate product can be separated into gasoline and distillate. A recycle stream comprising at least one of non-hydrotreated oligomerate product and hydrotreated oligomerate product is introduced into the oligomerization zone. The flow rates of non-hydrotreated oligomerate product and hydrotreated oligomerate product in the recycle stream are controlled to control the amount of gasoline and distillate product produced.

Abstract:
In a first processing chamber, a feedstock may be combined with plasma from three plasma torches to form a first fluid mixture. Each torch may have a working gas including water vapor, oxygen, and carbon dioxide. The first fluid mixture may be cooled and may contact a first heat exchange device. Water in the first heat exchange device may be converted to steam to generate electric power. The output fluid from the first heat exchange device may be separated into one or more components. A syngas may be derived from the one or more components and have a ratio of carbon monoxide to hydrogen of about 1:2. The syngas may be heated in a second processing chamber and then cooled to form a second admixture. The second admixture may contact a second heat exchange device that may make steam to power a second electrical generator.

An apparatus is disclosed. The apparatus includes a bubble implosion reactor cavitation device. The bubble implosion reactor cavitation device includes a tube-shaped cylindrical body including an upstream, a distal end surface and a downstream, proximal end surface. The tube-shaped cylindrical body defines an axial passage that extends through the tube-shaped cylindrical body between the upstream, distal end surface and the downstream, proximal end surface. The apparatus also includes a bubble generator subassembly connected to the tube-shaped cylindrical body. The bubble generator subassembly is at least partially disposed within the axial passage defined by the tube-shaped cylindrical body. The apparatus also includes a retaining member connected to the tube-shaped cylindrical body for retaining the bubble generator subassembly within the axial passage defined by the tube-shaped cylindrical body.
