PROCESS FOR THE SOLVENT DEASPHALTING OF ASPHALTENE- CONTAINING HYDROCARBONS

摘要

of the disclosure: A process for solvent deasphalting asphaltene-containing hydrocarbons which comprises mixing (A) asphaltene-containing hydrocarbons with (B) an amorphous silicon dioxide and/or a silicate compound and also with (C) a solvent such as n-heptane, n-hexane, n-heptane or a mixed n-pentane?n-butanol solvent, to form a mixture which is then allowed to stand still to precipitate and separate the asphaltene therefrom thereby obtaining a deasphalted oil,
