摘要: A method is disclosed for preparing fuel components from waste pyrolysis oil. Exemplary embodiments include providing a waste pyrolysis oil having plastic pyrolysis oil and/or tyre pyrolysis oil, and impurities; purifying the waste pyrolysis oil by hydrothermal treatment with water or alkaline water; separating the hydrothermally treated waste pyrolysis oil from an aqueous phase; preparing a hydroprocessing feed from the hydrothermally treated waste pyrolysis oil; hydroprocessing the hydroprocessing feed catalytically with hydrogen to cause hydrogenation; and recovering a hydrocarbon fraction boiling in a liquid fuel range.

摘要: A composition of matter is provided including one or more water-soluble oxidized disulfide oil (WS-ODSO) compounds or mixture of compounds, and an effective amount of an alkaline agent. The composition is a pH-modified, that is, deacidified, neutralized or basified, WS-ODSO composition. The pH-modified WS-ODSO composition can be used as a component in synthesis of materials such as zeolitic materials.

摘要: A process comprising creating an immiscible mixture by combining (a) a hydrocarbon feedstock containing contaminants and (b) a wash water, to create the immiscible mixture with at least three distinct layers: a hydrocarbon layer, a rag layer, and a brine layer. In this process a portion of the contaminants are removed from the hydrocarbon mixture where are then transferred to the brine layer. The brine layer is then separated from the immiscible mixture. In this process an alkalinity modifier is added in the process to reduce the emulsions in the immiscible mixture to create the at least three distinct layers.

摘要: A treatment process for preparing a remediated liquid from a contaminated liquid originally containing more than 5 ppm hydrogen sulfide (H2S) and substantially without formation of precipitate, includes steps of steps of adding an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 wt % to the contaminated liquid to achieve a concentration of 125-5000 ppm of the hydroxide compounds in the contaminated liquid, adding a fulvic acid and/or a humic acid to the contaminated liquid to achieve a concentration of 0.01-10 ppm of the acid(s) in the contaminated liquid, and dispersing the aqueous solution and the at least one organic acid in the contaminated liquid and allowing the aqueous solution and the at least one organic acid to react with the contaminated liquid for a period of time until a concentration of hydrogen sulfide in the contaminated liquid is reduced to ≤5 ppm.

摘要: A method of removing a metal contaminant from a light hydrocarbon stream comprises introducing a light hydrocarbon stream into a reactor vessel, the reactor vessel containing an aqueous treatment composition which comprises a treatment agent comprising one or more of the following: an alkali metal salt of a thiocarbonate; an alkaline earth metal salt of a thiocarbonate; an alkali metal salt of a tetrathioperoxy carbonate; or an alkaline earth metal salt of a tetrathioperoxy carbonate, the light hydrocarbon stream having an API gravity of greater than 28 degree determined in accordance with ASTM D 287-12 and comprising a metal contaminant; contacting the light hydrocarbon stream with the aqueous treatment composition generating a treated light hydrocarbon stream with a reduced level of the metal contaminant; and removing the treated light hydrocarbon stream from the reactor vessel.

摘要: The methods described herein provide an efficient way to remove and isolate short chain fatty acids from hydrocarbons that are produced upon the heating of a fatty acid resource. The short chain fatty acids can be continuously isolated and fed into the pyrolysis reactor, which in turn increases the overall efficiency of the production of the hydrocarbons. Alternatively, the short chain fatty acids can be isolated and used in other applications.

摘要: A process for the extraction and recovery of bitumen from oil sands using deionized silicate solutions. Bitumen is recovered in a process comprising contacting a deionized silicate solution with an ore sand oil to produce a froth comprising bitumen and a tailings stream comprising water, sand and clay fines and optionally unrecovered bitumen. Preferably the tailings stream is dewatered and recovered water may be recycled to the extraction process.
