Abstract
The sorbent of the present invention is useful in adsorbing petroleum-based products such as oil and gasoline, particularly from the surface of water. This sorbent, which is comprised of about 5 wt. % to about 70 wt. % cured, cross-linked resin and about 30 wt. % to about 95 wt. % fibers, selectively adsorbs the petroleum-based product due to its hydrophobicity.
Claims12
A method for adsorbing a petroleum-based product, comprising:
- intimately contacting the petroleum-based product with a sorbent such that said petroleum-based product is selectively adsorbed into said sorbent wherein said sorbent consists essentially of about 5 wt. % to about 70 wt. % cross-linked phenolic resin and about 30 wt. % to about 95 wt. % of a fibrous material comprising about 50% cellulose and about 40% polyester.
A method for adsorbing a petroleum-based product, comprising:
- intimately contacting the petroleum-based product with a sorbent such that said petroleum-based product is selectively adsorbed into said sorbent, wherein said sorbent consists essentially of about 15 wt. % to about 35 wt. % cross-linked phenolic resin and about 65 wt. % to about 85 wt. % of a fibrous material comprising about 50% cellulose and about 40% polyester.
