摘要： A combined process for treating heavy hydrocarbon feedstocks, such as resids that minimizes coke production and maximizes naphtha production, comprising the steps of thermally treating the feedstocks, in the absence of an added catalyst and either with or without hydrogen and steam, at a temperature of at least about 750.degree. F. (399.degree. C.) and under a pressure greater than about 400 psig to create significant chemical transformations without causing phase separation and consequent formation of sludge or a coke deposit; topping the thermally treated product to produce a distillate fraction and a bottoms fraction; coking the bottom fraction to produce gas, liquid products, and coke; and finally catalytically cracking the combined distillate fraction and liquid products to recover gas, gasoline, and light distillate products.

摘要： A process for preparing a pipelineable oil from a heavy crude oil by thermally treating the oil in the absence of added hydrogen, and under sufficiently severe conditions to induce the formation of an upgraded, low viscosity oil phase and a liquid asphalt phase that contains dispersed coke. The reaction is conducted under pressure sufficient to retain in the reactor most of the normally liquid hydrocarbons, under which conditions the two phases are readily separated and recovered solely by gravity settling. The process is readily adapted to oil field use with skid mounted units. The severity is adjusted to provide sufficient asphalt which, when burned, furnishes the steam required for production of the heavy crude oil.

摘要： A catalytic cracking process for heavy metals and asphaltene containing feed is disclosed. A reactive sulfur compound, preferably H.sub.2 S, is dissolved in the heavy feed and then kept at a temperature and for a time sufficient to at least partially decompose the metal containing compounds and also to reduce the molecular weight of the asphaltenes. Preferably a metal scavenging additive is added to the equilibrium catalyst. The additive will rapidly remove the thermal- and sulfur-treated metal containing compounds and prevent or minimize metals poisoning of the cracking catalyst. Sulfur induced cracking of heavy oil components reduces the viscosity of the heavy feed, and permits lower temperature to be used in the cracking reactor.

摘要： This invention provides a method for extending the catalytic dewaxing cycle time of a refined waxy lube stock. The method, in its broadest aspect, requires the additional refining step of thermally treating the refined waxy stock or precursor thereof for about 0.1 to about 2.0 hours at elevated temperature and at a pressure of 0 to 3000 psig (pounds per square inch gauge), and recovering an upgraded waxy stock having a reduced content of trace compounds that contain metals, nitrogen, sulfur and oxygen.In a specific embodiment of this invention, a vacuum residuum is thermally treated at a temperature of about 700.degree. F. to 950.degree. F. prior to solvent deasphalting and solvent extraction, and the waxy bright stock so formed is catalytically dewaxed with extended cycle time.

摘要： Use of a carbon-based catalyst composition, particularly activated-carbon, optionally containing at least one metal selected from Ni, Co, Mo, W, Fe, or mixtures thereof, for heavy oil hydroprocessing. Recovery and partial gasification of the catalyst to produce a synthesis gas and a partially gasified catalyst residue. Use of the synthesis gas in a process to produce synthetic hydrocarbons and use of the catalyst residue in steel or alloy production. Catalysts used for heavy oil hydrocarbon hydroprocessing frequently become contaminated with metals which increase the cost of disposal of the spent catalysts, e.g. landfills. This invention uses a specific catalyst for hydroprocessing which can then be partially gasified to produce a catalyst residue which can be further used in steel or alloy production, thereby reducing the need for expensive disposal.
