摘要:
The invention provides a process of converting shale oil fractions with the catalyst made by beginning the synthesis in the usual way and adding additional trivalent metal ion after crystallization is 20 to 90 percent complete and continuing the crystallization, whereby a zeolite having the same crystal structure throughout, but having different silica-to-alumina molar ratios in the inner core and outer shell is obtained.

An improved method for recovering and deasphalting tar sands comprises the use of at least two solvents in an extraction column to establish a liquid polarity gradient within it.
摘要:
A process for multi-solvent extraction is provided wherein polarity gradients induced by distillation are utilized for the extraction of petroleum residua and other heavy oils whereby a high quality maltenic fraction and a lower quality asphaltenic fraction are obtained.
摘要:
This invention relates to an improved process for reducing the pour point of oil feedstocks containing high levels of total nitrogen, e.g. shale oil or fractions thereof, wherein the same is contacted with a catalyst comprising a boron-containing crystalline material having the structure of zeolite ZSM-5 under conditions including elevated temperature and pressure.
摘要:
Residual oil fractions are upgraded in that CCR is selectively removed without undue hydrogen consumption by hydroprocessing with a catalyst comprises a single metal such as molybdenum, tungsten, nickel, iron or palladium or multimetallic combination of such metals, excluding, however, active desulfurization compositions such as nickel molybdenum and nickel-tungsten. Said catalyst is characterized as having greater than about 50% of its pore volume contribution in pores having diameters in the range of between about 100 and 200 Angstroms. The product of such hydroprocessing is a particularly preferable feedstock for coking to give more liquid yield and less coke make.

An improved method for deasphalting residua or heavy oils comprises the use of at least two solvents in an extraction column to establish a liquid polarity gradient within it.
摘要:
This invention relates to a process for improving the yield and properties of jet fuel from a kerosene feed. More particularly, a kerosene feedstock is hydrotreated and dewaxed using a ZSM-48 catalyst to produce a jet fuel in improved yield and having improved properties.
摘要:
A method for making a mesoporous or combined mesoporous/microporous inorganic oxide includes reacting a source of inorganic oxide with a complexing agent at a complexation temperature to provide a complex; decomposing the complex to provide a porous material precursor having an inorganic oxide framework containing at least some organic pore-forming agent; and removing the organic pore forming agent from the inorganic oxide framework by solvent extraction and/or calcination.
摘要:
A catalytic material includes microporous zeolites supported on a mesoporous inorganic oxide support. The microporous zeolite can include zeolite Beta, zeolite Y (including “ultra stable Y”—USY), mordenite, Zeolite L, ZSM-5, ZSM-11, ZSM-12, ZSM-20, Theta-1, ZSM-23, ZSM-34, ZSM-35, ZSM-48, SSZ-32, PSH-3, MCM-22, MCM-49, MCM-56, ITQ-1, ITQ-2, ITQ-4, ITQ-21, SAPO-5, SAPO-11, SAPO-37, Breck-6, ALPO4-5, etc. The mesoporous inorganic oxide can be e.g., silica or silicate. The catalytic material can be further modified by introducing some metals e.g. aluminum, titanium, molybdenum, nickel, cobalt, iron, tungsten, palladium and platinum. It can be used as catalysts for acylation, alkylation, dimerization, oligomerization, polymerization, hydrogenation, dehydrogenation, aromatization, isomerization, hydrotreating, catalytic cracking and hydrocracking reactions.
