Abstract
The present disclosure provides hydrocarbon absorbent granules, comprising granulated particles each including a mixture of hydrophobic non-self associating raw cotton sorbent fibers and a binding agent. The granules have an average diameter in a range from about 1 to about 7 cm and have a density in a range from about 0.03 to 0.1 grams per cubic centimeter. The binding agent constitutes from about 0.5 to about 70 percent by weight of granule. The granules are characterized in that they exhibit a sorbency ratio in a range from about 7 to about 30.
