摘要:
The present invention relates to a hydrocracking catalyst for hydrocarbon oil comprising a support containing a framework-substituted zeolite-1 in which zirconium atoms and/or hafnium atoms form a part of a framework of an ultrastable y-type zeolite and a hydrogenative metal component carried thereon and a method for producing the same. The hydrocracking catalyst of the present invention makes it easy to diffuse heavy hydrocarbon oils such as VGO, DAO and the like into mesopores, is improved in a cracking activity and makes it possible to obtain a middle distillate at a high yield as compared with catalysts prepared by using zeolite comprising titanium and/or zirconium carried thereon.
摘要:
A crude oil feedstream is treated to remove or reduce the content of known undesired heteroatomic and polynuclear aromatic compounds containing nitrogen and sulfur by contacting the feedstream with one or more solid adsorbent materials selected from attapulgus clay, alumina, silica gel and activated carbon in a mixing vessel for a time that is sufficient to optimize the adsorption of the undesired compounds from the crude oil, subjecting the mixture to atmospheric flash distillation and then to vacuum flash distillation to recover presorbed boiling ranges of products having a lowered content of the undesired compounds, and preferably regenerating at least a portion of the solid adsorbent material for reuse in the process.
摘要:
A cost-effective solution is provided for eliminating refinery process waste, including spent catalytic and non-catalytic adsorbent materials, as well as adsorbate process reject materials derived from desorption, while minimizing conventional waste handling demands. An asphalt composition includes asphalt and spent adsorbent material from a solvent deasphalting unit. The asphalt can comprise asphaltic material obtained from a solvent deasphalting unit, and spent adsorbent material in the asphalt composition was previously utilized in the solvent deasphalting unit. The asphalt composition can also include process reject materials.
摘要:
A system and a method for determining one or more distillation temperatures for one or more given distillation weight percentages of a crude oil sample are provided, which can be used to produce a simulated distillation curve. Simulated distillation temperatures of crude oil samples are assigned as a function of density and data derived from UV/Visible spectroscopy measurement of the crude oil samples.

摘要:
Initial high sulfur levels of a hydrocarbon feedstock are reduced to desired low levels without the need for integration of substantial new equipment or hardware with existing hydroprocessing reactors. Ionic liquids are utilized as organic sulfur extraction agents and are added to and mixed with the hydrocarbon feedstock containing organosulfur compounds in, or upstream of, an existing cold separator vessel. The ionic liquid and hydrocarbon mixture is maintained in contact under conditions which promote the formation of ionic sulfur-containing derivatives that are soluble in the ionic liquid to be formed, thereby enabling extractive removal and separation of the organosulfur compounds from the feedstock.
