摘要:
A method of agglomerating coal particles, a portion of the coal particles having a fine particle size comprising (a) separating at least part of the coal particles having a fine particle size to provide a first fraction of coal particles having a reduced coal fines content; (b) contacting a slurry of coal particles of the first fraction with hydrocarbon oil to form coal-oil agglomerates; and (c) recovering coal-oil agglomerates of reduced oil content.
摘要:
A process for producing coke from sulfur-containing hydrocarbon feedstocks which involves contacting at least a portion of the feedstock with a peroxy oxidant in the presence of a metal-containing catalyst to preferentially oxidize a portion of the hydrocarbon feedstock, subjecting the feedstock to coking conditions to form coke and recovering a coke product. The present process can provide improved yields of coke having substantially reduced sulfur content.
摘要:
A method for preparing an improved composition of matter whereby a solid catalyst comprising alumina derived from hydrous alumina predominating in alumina trihydrates and at least one platinum group component is used in hydrocarbon conversion service for a period of time to reduce the surface area of said solid catalyst to from about 20% to about 90% of the surface area of the original solid catalyst. This decreased area solid catalyst is treated with at least one metal promoter to produce a treated catalyst having improved properties. An improved method for hydrocarbon conversion using this treated catalyst is also disclosed.
