    摘要: A method of improving hydrocarbon recovery from oil sands, oil shale, and petroleum residues includes adding a polymeric or nonpolymeric processing aid capable of sequestering cations, such as the multivalent calcium, magnesium and iron cations. The hydrocarbons are preferably contacted with the processing aid before a primary separation of the hydrocarbons in order to increase bitumen recovery. A processing aid is provided in an effective amount to increase the liberation of the hydrocarbons from inorganic solids, particularly when the source is a poor processing ore. Preferred processing aids include citric acid or a polymeric acid selected from polyacrylic acid, polymethacrylic acid, salts of these acids, partial salts of these acids, and combinations thereof. The processing aids significantly increase the hydrocarbon recovery typically with concentrations less than 50 ppm and the polymeric processing aids can also provide beneficial flocculation of solids in tailings slurry.
