摘要： Heavy crude oils which contain metal contaminants such as nickel, vanadium and iron may be separated from light hydrocarbon oils by passing a solution of the crude oil dissolved in a cycloparaffinic hydrocarbon solvent containing from about 5 to about 8 carbon atoms by passing through a polymeric membrane which is capable of maintaining its integrity in the presence of hydrocarbon compounds. The light hydrocarbon oils which possess relatively low molecular weights will be recovered as the permeate while the heavy oils which possess relatively high molecular weights as well as the metal contaminants will be recovered as the retentate.

摘要： Production of a low mineral content fuel by a coal liquefaction process utilizing a hydrogenated coal solvent having been hydrogenated to remove at least about 80% of the asphaltenes which yields as the primary product a mixture of liquid and solids, a part of which is suspended in the liquid. The suspended solids are effectively removed with minimum loss of desired product by means of a light aromatic solvent in combination with a hydrogenated coal solvent.

摘要： A process for deashing primary coal liquids with a selective hydrocarbon solvent separation wherein the coal liquids and selective hydrocarbon solvent are contacted initially at a temperature greater than the temperature at which the deashing separation occurs. More particularly, a process for the production of deashed coal liquid which comprises the sequential steps of: (a) admixing a primary coal liquid containing ash and a hydrocarbon deashing solvent having no hydrogen-transferring ability at a selected admixing temperature from about 250.degree. F. to about 575.degree. F.; (b) reducing the temperature of the entire resulting admixture of the primary coal liquid and hydrocarbon deashing solvent to a deashing temperature about 50.degree. F. to about 125.degree. F. less than the admixing temperature of step (a); and deashing the primary coal liquid with the deashing solvent at the deashing temperature of step (b).
