According to this invention, substantially hydrocarbonaceous fractions comprising diamondoid compounds are peculiarly suitable for separation by a thermal gradient diffusion process. Applicability of this process to this service is dependent upon the fact that the diamondoid compounds exhibit a large change in viscosity relative to temperature, that is, their viscosity goes down significantly per degree of increase in temperature.

A process for removing diamondoid compounds from a hydrocarbonaceous fluid containing such, which comprises passing said fluid between two surfaces spaced apart up to about 0.01 inch at a temperature higher than the melting point of the lowest melting diamondoid in said fluid up to about 500°F., and

A process for removing diamondoid compounds from a hydrocarbonaceous fluid containing such, which comprises passing said fluid between two surfaces spaced apart up to about 0.01 inch at a temperature higher than the melting point of the lowest melting diamondoid in said fluid up to about 500°F., and at a temperature differential between said surfaces of at least about 10°F. for a time sufficient to recover therefrom a first stream enriched in said diamondoid compounds, and a second stream depleated in said diamondoid compounds.
