Abstract
In a process for separating linear from branched hydrocarbons, the feed is brought in contact with a carbon membrane with critical size from 0.39 to 0.55 nm. The isomer with the larger size remains on the feed side. A membrane can be produced by activating a membrane by reacting it with oxygen and then with hydrogen.
