摘要： 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.

摘要： A particle measurement system using a single component light collecting system with an aperture having a portion within direct view of the light detector. An aperture assembly extending into a sample may be self-concealing by having an extended portion to block light from directly illuminating the light detector. Alternatively, a smooth, reflective inside surface of the aperture assembly provides for self-concealment by causing spontaneous emitted light to have low angles of reflection. In either case, spontaneously emitted light is substantially prevented from reflecting directly into the light detector, thereby reducing light noise to the level of molecular noise.

摘要： A process is disclosed for extracting diamondoid compounds from a hydrocarbon gas stream. The process includes two stages, each of which alone is effective to remove diamondoids from a hydrocarbon gas stream. The first stage comprises contacting the diamondoid-laden hydrocarbon gas with a suitable solvent to preferentially dissolve the diamondoids into the solvent. Diesel fuel is the preferred solvent for this first stage. The second stage comprises sorbing diamondoids from the diamonoid-laden hydrocarbon gas with silica gel. The most preferred embodiment of the invention is a serial process in which a diamondoid-laden gas is first treated in the solvation stage and the partially purified gas is further resolved in the silica gel sorption stage. The invention still further includes a process for segregating adamantane and diamantane when both are separated from a hydrocarbon gas stream.
