20130020232 | MOLTEN SALT ROLLING BUBBLE COLUMN, REACTORS UTILIZING SAME AND RELATED METHODS - Reactors for carrying out a chemical reaction, as well as related components, systems and methods are provided. In accordance with one embodiment, a reactor is provided that includes a furnace and a crucible positioned for heating by the furnace. The crucible may contain a molten salt bath. A downtube is disposed at least partially within the interior crucible along an axis. The downtube includes a conduit having a first end in communication with a carbon source and an outlet at a second end of the conduit for introducing the carbon material into the crucible. At least one opening is formed in the conduit between the first end and the second end to enable circulation of reaction components contained within the crucible through the conduit. An oxidizing material may be introduced through a bottom portion of the crucible in the form of gas bubbles to react with the other materials. | 01-24-2013 |
20130026062 | INTEGRATED SYSTEM AND PROCESS FOR IN-SITU ORGANIC PEROXIDE PRODUCTION AND OXIDATIVE HETEROATOM CONVERSION - An oxidative treatment process, e.g., oxidative desulfurization or denitrification, is provided in which the oxidant is produced in-situ using an aromatic-rich portion of the original liquid hydrocarbon feedstock. The process reduces or replaces the need for the separate introduction of liquid oxidants such as hydrogen peroxide, organic peroxide and organic hydroperoxide in an oxidative treatment process. | 01-31-2013 |
20130220881 | PRODUCTION OF HIGH-CETANE DIESEL PRODUCT - Exemplary embodiments of the invention provide a process of increasing the cetane number rating of a diesel oil feedstock. The process involves reacting a diesel fuel feedstock in liquid form with ozone in gaseous form in the presence of an alcohol having two or more carbon atoms and at least one polar solvent different from the alcohol, thereby forming an ozonated diesel oil containing oxidized byproducts, wherein the alcohol and said polar solvent are employed in amounts totaling no more than about 10 vol. % of the feedstock. The oxidized byproducts are then separated from the ozontated diesel oil to produce a hydrocarbon product of increased cetane number rating relative to the feedstock oil. The product can be used as a diesel fuel or as a diesel fuel extender mixed with conventional diesel fuel of low cetane number. | 08-29-2013 |
20130292297 | OZONATION CONVERSION OF HEAVY HYDROCARBONS FOR RESOURCE RECOVERY - A method for upgrading heavy hydrocarbons into more usable hydrocarbon products is provided. The method provides for the steps of adding heavy hydrocarbons to a solvent system to form a reaction medium, and ozonating the reaction medium with an ozone containing gas to provide ozonation products. The solvent system can include a first solvent that solubilizes at least a portion of the heavy hydrocarbons and a reactive solvent which reacts with ozonation intermediates. Reactive solvent is maintained at concentrations sufficient to decompose ozonation intermediates. | 11-07-2013 |

208005000 | In presence of soild contact material | 1 |
20100320118 | OXIDATION OF ASPHALTENES - A method for processing asphaltenes is disclosed. The method can include separating asphaltenes from an asphaltene-containing composition and oxidizing the separated asphaltenes to form oxidation products. Alternatively, the method can include oxidizing asphaltenes within an asphaltene-containing composition without first separating the asphaltenes. Once formed, the oxidation products can be combined with other hydrocarbons. The amount of oxidation can be limited to an amount sufficient to produce a mixture suitable for the desired application. This method can be used to upgrade asphaltenes from a variety of sources, including oil sands. The oxidation step can be performed, for example, by introducing an oxidizing agent and, in some cases, a catalyst into the asphaltenes. A solvent or miscibility agent also can be introduced to improve mixing between the oxidizing agent and the asphaltenes. | 12-23-2010 |
208006000 | Tar, pitch, or asphalt feed | 3 |
20130228493 | Falling Film Reactor for Light Tar Oxidation - A method of processing light fraction tar includes pre-heating the light fraction tar before directing it through a reactor. The reactor has a top and a bottom and a surface spanning between said top and said bottom. A film of the light fraction tar flows down the surface under the force of gravity and with heated gas blowing thereon. The portion of the film that reaches the bottom of the reactor has improved properties making it more widely useful for carbon products. | 09-05-2013 |
20140262935 | ASPHALT OXIDATION TECHNIQUE - The present invention relates to a method for oxidizing asphalt which comprises dispersing an oxygen containing gas throughout an asphalt flux in an oxidation zone while the asphalt flux is maintained at a temperature which is within the range of about 400° F. to 550° F., wherein the oxygen containing gas is introduced into the oxidation zone through a recycle loop. The recycle loop pumps asphalt flux from the oxidation zone and reintroduces the asphalt flux into the oxidation zone as oxygen enhanced asphalt flux. The recycle loop will typically include a pump which pulls the asphalt flux from the oxidation zone and which pumps the oxygen enhanced asphalt flux into the oxidation zone, and wherein the oxygen containing gas is injected into the recycle loop at a point before the asphalt flux enters into the pump. | 09-18-2014 |
20140374310 | ASPHALT OXIDATION PROCESS USING LIQUID JET EJECTION - Provided is a process for increasing the softening temperature of asphalts by use of liquid jet ejector with a diptube connected to the discharge connection of the liquid jet ejector for ejecting an air/asphalt mixture below a liquid level in an oxidizer vessel. The liquid jet ejector is used as both an air compressor and an air/oil mixer. The liquid jet ejector motive fluid is hot asphalt and the entrained vapor is air. The combined liquid jet ejector with a diptube process provides for an improvement in asphalt air blowing efficiency by requiring less cumulative air to produce a given asphalt softening temperature. | 12-25-2014 |
208007000 | With cracking | 1 |
20160060550 | UPGRADING HEAVY OILS BY SELECTIVE OXIDATION - A heavy petroleum oil feed is upgraded by having its amenability to cracking improved by subjecting the oil to selective partial oxidation with a catalytic oxidation system to partially oxidize aromatic ring systems in the heavy oil. The partially oxidized oil can then be cracked in the conventional manner but at lower severities to lower molecular weight cracking products. The cracking following the partial oxidation step may be thermal in nature as by thermal cracking, delayed, contact or fluid coking or fluid catalytic cracking or hydrogenative as in hydrocracking. | 03-03-2016 |
