Abstract:
Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed has a residue content of at least 0.2 grams of residue per gram of crude feed. The one or more catalysts include a transition metal sulfide catalyst. The crude product is a liquid mixture at 25° C. and 0.101 MPa. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.
Abstract:
A process for reducing content of sulphur compounds and polyaromatic hydrocarbons in a hydrocarbon feed having a boiling range between 200° C. and 600° C. is disclosed. The process comprises in combination contacting the feed and hydrogen over a hydrotreating catalyst and hydrotreating feed at hydrotreating conditions, cooling the hydrotreated effluent and hydrogen-rich gas from the hydrotreating reactor and contacting the effluent and hydrogen gas over a hydrotreating catalyst in a post-pretreatment reactor at a temperature sufficient to lower the polyaromatic hydrocarbon content.
Abstract:
Fuel mixtures for direct methanol fuel cells are disclosed. The fuels include methanol and additives that react with water to produce methanol and other easily electro-oxidizable compounds including dimethyloxymethane, methylorthoformate, tetramethylorthocarbonate, trimethylborate, and tetramethylorthosilicate. Other additives to improve safety and efficiency of the fuel cell include sulfonated activated carbon particles and metal hydrides, such as LiAlH4, NaBH4, LiBH4, (CH3)2 NHBH3, NaAlH4, B2H6, NaCNBH3, CaH2, LiH, NaH, KH or sodium bis (2-methoxyethoxy) dihydridaluminate.
Abstract:
The present invention relates to a method and system for the continuous preparation of gasoline, kerosene, and diesel oil from waste plastics. The method comprises the steps of: subjecting a melt of the waste plastics to a first catalytic reaction in which the waste plastic melt is in contact with a nickel or nickel alloy catalyst to be dehydrogenated while being decomposed; subjecting the dehydrogenated and decomposed waste plastic melt to a fluid catalytic cracking, as a second catalytic reaction to produce a gasoline-based fraction at a high fraction; fractionating the cracked material into a gasoline-based fraction, a kerosene fraction, and a diesel oil fraction; and reforming the gasoline-based fraction to produce a high octane number gasoline. The present invention can apply to a small scale facility, not to apply to a large scale facility. Also, the present invention allows gasoline to be prepared from the waste plastics in a high fraction and an efficient manner, thereby contributing to resource reclamation and environment protection.
Abstract:
The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.
Abstract:
This invention describes systems and methods for mixing two fluids. A first fluid, usually fuel, can be passed through a primary passage that typically leads to a carburetor or other inlet to a combustion engine. A second fluid, usually air, can be mixed with the first by introducing it to the primary passage through an inlet located upstream in the primary passage. The mixture of fluids can then be further emulsified by passing it over a plurality of obstructions, such as a threaded interior surface of the primary passage, located within the primary passage downstream of the inlet.
Abstract:
A Fischer-Tropsch derived distillate fraction is blended with either a raw gas field condensate distillate fraction or a mildly hydrotreated condensate fraction to obtain a stable, inhibited distillate fuel.
Abstract:
A liquid fuel for combustion appliances, in which a combustion wick for sucking up the fuel by the utilization of capillarity is used, contains an alcohol as a principal constituent and contains a hydrocarbon compound, which has approximately the same boiling point as that of the principal constituent, as a flame reaction agent. By the addition of the flame reaction agent, which is not accompanied by the occurrence of clogging of the combustion wick, the combustion flame of an alcohol, which otherwise produces a colorless flame, is colored and its visual perceptibility is thereby enhanced, such that the structure of the combustion appliance may be kept simple and the flame stability may be obtained reliably.
Abstract:
Methods for enhancing the flow behavior and stability of hydrothermally treated slurry fuels. A mechanical high-shear dispersion and homogenization device is used to shear the slurry fuel. Other improvements include blending the carbonaceous material with a form of coal to reduce or eliminate the flocculation of the slurry, and maintaining the temperature of the hydrothermal treatment between approximately 300.degree. to 350.degree. C.
Abstract:
Petroleum products are marked with a marker such as thymolphthalein or cresolphthalein. When the marked petroleum products are contacted with a developing reagent, a color develops.
