摘要： High energy (e.g., ultrasonic) mixing of a liquid hydrocarbon feedstock and reactants comprised of an oxidation source, catalyst and acid yields a diesel fuel product or additive having substantially increased cetane number. Ultrasonic mixing creates cavitation, which involves the formation and violent collapse of micron-sized bubbles, which greatly increases the reactivity of the reactants. This, in turn, substantially increases the cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. Alternatively, an aqueous mixture comprising water and acid can be pretreated with an oxidation source such as ozone and subjected to ultrasonic cavitation prior to reacting the pretreated mixture with a liquid hydrocarbon feedstock.

摘要： The present invention provides a process for de-acidifying crude oil and/or crude oil distillate, said process comprising: (a) contacting crude oil and/or crude oil distillate with a Group IIA metal hydroxide in the presence of water, wherein water is present in a concentration of 0.01 to 100 wt.% of the crude oil and/or crude oil distillate; and (b) introducing a demulsifier to the mixture of crude oil and/or crude oil distillate, Group IIA metal hydroxide and water, in an amount effective to cause the mixture to separate into an oil-rich phase, an aqueous phase and an interface layer disposed between the oil-rich phase and aqueous phase.

摘要： The present disclosure relates to a process for reducing the sulphur content of hydrocarbon feedstocks such as Natural Gas Condensate, Kerosene, Jet Fuel, Diesel, Vacuum Gas Oil and Fuel Oil. The process uses a tailored oxidation process comprising one or two oxidation steps to produce sulphoxides and/or sulphones. These sulphoxides and sulphones, while being still present in the liquid hydrocarbon streams, are subsequently extracted thereby producing a low sulphur hydrocarbon stream and optionally following further treatment of the sulphoxides and/or sulphones, produce a low sulphur aromatic hydrocarbon stream and an aqueous stream of sodium sulphite or sulphuric acid. The low sulphur hydrocarbon stream and low sulphur aromatic hydrocarbon stream may be individually recycled or combined for recycling.

摘要： Trace amount levels of heavy metals such as mercury in crude oil are reduced by contacting the crude oil with an oxidizing agent and then with a reducing agent. In one embodiment, the oxidizing agent is selected from the group of hydroperoxides, organic peroxides, inorganic peracids and salts thereof, organic peracids and salts thereof, halogens such as iodine (I
2 ), bromine (Br
2 ), and ozone. The treatment converts non-volatile mercury in the crude oil into a volatile form for subsequent mercury removal by any of stripping, scrubbing, adsorption, and combinations thereof. In one embodiment, at least 50% of the mercury is removed. In another embodiment, the removal rate is at least 99%.-

摘要： Trace amount levels of heavy metals such as mercury, arsenic, etc., in crude oil are reduced by contacting the crude oil with an oxidizing agent, extracting heavy metals into a water phase for subsequent separation from the crude oil. In one embodiment, the oxidizing agent is selected from the group of hydroperoxides, organic peroxides, inorganic peracids and salts thereof, organic peracids and salts thereof, halogens such as iodine (I2), bromine (Br2), and ozone. In another embodiment, at least a complexing agent selected from the group of metal halides and/or sulfur compounds can be added to facilitate the removal of heavy metals from crude oil by forming soluble heavy metal complexes in the water phase.

摘要： An acidic crude oil (more especially one containing naphthenic acids) and an effective amount of an aqueous base solution are combined at conditions of pH and temperature sufficient to form an unstable emulsion of the acidic crude oil in the aqueous base solution. The emulsion is broken to form a phase containing crude oil having a decreased acidity and aqueous phase containing residual base and neutralized acids. When the acidic crude oil also contains calcium then decrease in calcium content can also be achieved.
