Separation of sulfur and trace elements from high-viscosity petroleums and tar sands
Characteristic features of high-viscosity petroleums and tar sands of western Kazakhstan are a great chemical nonuniformity, a diverse combination of proportions of aromatic and heteroatomic structures, and a wide variation in trace-element composition. They contain, moreover, large quantities of aliphatic ethers and esters, sulfo acids, cyclic hydrocarbons, and other valuable components that may be used in the chemical, petrochemical, and other industries. The authors study employed acetylacetone or propanol for organic solvent extraction of a sulfurous concentrate, magnifying the selective separation of organosulfur compounds with the use of ultrasonic phase stratification. Oxidation of organosulfur compounds to sulfoxides, sulfones, and sulfo acids was accomplished with ionizing radiation from Co{sup 60}. 17 refs., 2 tabs.
