Particulate oil-absorbing composition to absorb oil
First Claim
1. A particulate oil-absorbing composition which in dust form displays a low explosion hazard and a low flammability, but which after absorption of oil is flammable and entirely consumed when burned, the particles consisting essentially of as the major component at least 50% by weight hydrophobic cellulose pulp fibers in admixture with at least 30% up to 50% of an inorganic cellulose paper pulp filler.
