Abstract:
A reaction system and method for removing heteroatoms from oxidized-heteroatom-containing hydrocarbon streams and products derived therefrom are disclosed. An oxidized-heteroatom-containing hydrocarbon feed is reacted in a reaction system thereby forming non-ionic hydrocarbon products. The products derived therefrom are useful as transportation fuels, lubricants, refinery intermediates, or refinery feeds.
Abstract:
This invention relates to a method for refining vegetable oils, in particular cottonseed oil or a possible mixture of it with others, as substitute of diesel fuel remarkable in that a sequence of treatment steps to be performed on crude vegetable oil, including: a) a pre-treatment thereof consisting of the removal of oil insoluble impurities from the crude oil, b) removal of oil soluble impurities therefrom, c) a free acid neutralization thereof, and d) a drying, bleaching and filtration thereof. This invention also relates to an Additive of organic basis, containing ether, ketone, toluene, hexane, turpentine, alcohols in specific concentrations.
Abstract:
This invention relates to the electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams to mercaptans that can then be removed, in one embodiment, by caustic extraction. In another embodiment, the mercaptans can be thermally decomposed, removing sulfur as hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means without the required addition of hydrogen and in the substantial absence of water.
Abstract:
BY CONTACT WITH METHYL ISOBUTYL KETONE. METHYL ISOBUTYL KETONE IS REGENERATED BY DISTILLATION TO SEPARATE PHENOLS.
A NON-CAUSTIC REGENERATIVE PROCESS FOR REMOVING PHENOLS FROM GASOLINE IS DESCRIBED. THE PROCESS EMPLOYS AN AQUEOUS SOLUTION OF TRI-SODIUM PHOSPHATE WHICH IS REGENERATED BY EXTRACTION TO REMOVE PHENOLS THEREFROM
Abstract:
Systems and methods for pretreating a raw mixed plastic waste pyrolysis oil to remove silicon and chloride contaminants using an aqueous alkaline hydroxide solution. Specifically, these systems and methods lead to at least about 30 weight percent reduction in the silicon compounds present in the pyrolysis oil and at least about 50 weight percent reduction in the chloride compounds in the pyrolysis oil.
