Azeotropic distillation process for recovery of diamondoid compounds from hydrocarbon streams

Patent ·
OSTI ID:7152528
This patent describes a method for separating a diamondoid compound selected from the group consisting of adamantane, diamantane, triamantane and the alkyl substituted homologs of adamantane, diamantane, and triamantane from a hydrocarbon compound. This patent also describes a method for extracting diamondoid compounds from a hydrocarbon gas containing the same. It comprises providing a hydrocarbon gas stream containing a recoverable concentration of at least one concentration of at least one diamondoid compound; contacting the hydrocarbon gas stream with a liquid hydrocarbon solvent in which the diamondoid compound is at least partially soluble to dissolve the diamondoid compound in the liquid hydrocarbon solvent; and distilling the diamondoid-containing hydrocarbon solvent of step in the presence of water sufficient to cause an azeotrope with the diamondoid compound.
