Abstract
Disclosed herein is a hydrophobic sorbent, particularly useful for the sorption of oil or other similar tacky or viscous hydrocarbons, which is prepared by subjecting a water-containing, fibrous cellulosic product, particularly sulphite reject fibers, to rapid heating to cause expansion of the fibers through gasification of the water therein. The sorbent is capable of exceptionally rapid and tight sorption and binding of even heavy oils.
