摘要： A process is provided to dedust oil derived from solid hydrocarbon-containing material, such as oil shale, coal or tar sand in multi-stage desalters. In the process, water is dispersed into the oil before entering each desalter to form an emulsion. The desalter separates the emulsion into a stream of oil having a substantially lower concentration of dust and a dusty stream of water containing most of the dust. In one embodiment, the sludge-like dusty stream from the first desalter is combusted in a lift pipe and used as heat carrier material in the retort. In other embodiments, the dusty stream from the first desalter is centrifuged or filtered and thereafter heated in a dryer to remove residual oil and water from the stream before the stream is combusted in the lift pipe and used as heat carrier material in the retort and dryer. Effluent water from the second and third desalters as well as from the centrifuge or filter are recycled upstream and dispersed in the oil.

摘要： Disclosed is an improved catalyst suitable for use in an ebullated bed process for the hydrodemetallation, hydrodesulfurization, and hydrocracking of heavy hydrocarbon feedstocks containing asphaltenes, metals, and sulfur compounds. The disclosed catalyst comprises a relatively small amount of cobalt, i.e., 0.4 to 0.8 wt. % incorporated with a high macropore volume Group VIB metal containing catalyst.

摘要： A method for stabilizing oil is provided. An oil fraction having hydrocarbons with an initial boiling point of about 200.degree. F. to about 1050.degree. F. is hydrotreated to reduce the nitrogen content of the oil fraction to be stabilized. Subsequently, condensed aromatic compounds are selectively extracted from the hydrotreated oil fraction to yield a stable oil fraction.

摘要： Disclosed is a hydrocracking process wherein the feedstock is contacted in a first reaction zone with a first reaction zone catalyst comprising a nickel component and a tungsten component deposed on a support component consisting essentially of an alumina component and a crystalline molecular sieve component. The effluent from the first reaction zone effluent is then contacted in a second reaction zone with a second reaction zone catalyst comprising a cobalt component and a molybdenum component deposed on a support component comprising an alumina component and a crystalline molecular sieve component.

摘要： Disclosed is an improved hydroconversion process for the hydroconversion of heavy hydrocarbon feedstocks containing asphaltenes, metals, and sulfur compounds which process minimizes the production of carbonaceous insoluble solids and catalyst attrition rates. The process is characterized by the use of a catalyst which has about 0.1 to about 0.3 cc/gm of its pore volume in pores having diameters greater than 1,200.ANG. and no more than 0.1 cc/gm of its pore volume in pores having diameters greater than 4,000.ANG..
