摘要:
Procédé de purification d'une composition comprenant une huile de pyrolyse de plastique comprenant un traitement par une base forte en présence d'un alcool. Le procédé est utile pour abattre la concentration en hétéro-éléments dans ladite composition en vue de la rendre compatible pour introduction comme charge dans des procédés de conversion tels que le vapocraquage, le craquage catalytique en lit fluidisé, l'hydrogénation catalytique ou l'hydrocraquage.

摘要:
In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non- dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced.
摘要:
Methods for producing phase stable, reduced acid biomass-derived pyrolysis oils are provided. Biomass-derived pyrolysis oil having a determined water content no greater than 30% by weight is provided. A base is mixed with the biomass-derived pyrolysis oil to produce reduced acid biomass-derived pyrolysis oil. A base is selected from an inorganic base or a nitrogen-containing base.

摘要:
The present invention relates to making tetra-sulfo iron-phthalocyanine by reacting sulfonated reactant(s) in the presence a boron-containing promoter. The present invention also relates to making tetra-sulfo iron-phthalocyanine more tolerant to oxygen by combining the tetra-sulfo iron-phthalocyanine with a stabilizing amount of a complexing agent (e.g., a stabilizing amine) and/or contacting the tetra-sulfo iron-phthalocyanine with steam.
摘要:
The disclosed process removes or reduces impurities such as asphaltenes, solids (especially solid fines), sulfur, metals, chlorides, water, salts, and acids from bitumen, oil sands, and crude oils with a wide range of gravities. A crude source composition is contacted with one or more zeolite materials to remove asphaltenes, solids, sulfur, NSO, metals, chlorides, water, salts, and/or acids from the composition. The crude source is typically diluted with a hydrocarbon solvent such as naphtha before contacting the zeolite(s). The disclosed processes represent an improvement over prior and presently available processes because the disclosed processes are capable of processing emulsions.
摘要:
This invention is a method for reducing the total acid number of organic acid containing petroleum oil comprising forming a water-in-oil emulsion comprising an aqueous Group IIA metal hydroxide solution or slurry in a hydrocarbon oil, said water-in-oil emulsion having an aqueous droplet particle size diameter of from 1 to 25µ, adding the water-in-oil emulsion to the organic acid containing petroleum oil and permitting the mixture to stand for a time sufficient to permit the neutralization of the organic acids in the petroleum oil.
摘要:
Methods for removing mercaptans from hydrocarbons streams, for example crude oil and natural gas, are provided. The methods use basic metal salts which react with mercaptans to form mercaptides. The metal salts are dissolved or suspended in ionic liquids, which tend to have virtually no vapor pressure. After the mercaptides are adsorbed into the ionic liquid, the demarcaptanized hydrocarbon stream can be removed, for example by distillation, decantation or gravity separation. Then the mercaptides can be oxidized, for example, by exposure to air, to form disulfides. The disulfides are insoluble in the ionic liquids, and can be readily removed. Sodium hydroxide is a preferred salt. Non-water reactive ionic liquids are preferred. The mercanptan-containing hydrocarbon stream can be in the gas phase or in the liquid phase. The flow of hydrocarbon stream over/through the ionic liquid can be for example, co-current, counter-current, or staged in stirred tanks, with countercurrent being preferred.
