Disclosed are processes for the recovery and purification of higher diamondoids from a hydrocarbonaceous feedstock. Specifically disclosed is a multi-step recovery process for obtaining diamondoid compositions enhanced in tetramantane components and other higher diamondoid components. Also disclosed are compositions comprising at least about 10 weight percent of non-ionized tetramantane components and other higher diamondoid components and at least about 0.5 weight percent of non-ionized pentamantane components and other higher diamondoid components based on the total weight of diamondoid components present.
La présente invention concerne des procédés de récupération et de purification de diamantoïdes supérieurs à partir d'une charge hydrocarbonée. Plus précisément, l'invention concerne un procédé de récupération à étapes multiples permettant d'obtenir des compositions de diamantoïdes enrichies en constituants de tétramantane et d'autres constituants de diamantoïdes supérieurs. L'invention concerne également des compositions comprenant au moins environ 10% en poids de constituants de tétramantane non ionisés et d'autres constituants de diamantoïdes supérieurs et au moins 0,5% en poids de constituants de pentamantane et d'autres constituants de diamantoïdes supérieurs par rapport au poids total des constituants de diamantoïdes présents.
