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.
Claims21
Hydrocarbon absorbent granules, comprising:
- granulated particles each including a mixture of hydrophobic non-self associating raw cotton sorbent fibers and a binding agent, said granules having an average diameter in a range from about 1 to about 7 cm, said granules having a density in a range from about 0.03 to 0.1 grams per cubic centimeter, said binding agent constitutes from about 0.5 to about 70 percent by weight of the granules, said granules characterized in that they exhibit a sorbency ratio in a range from about 7 to about 30.
A method of producing absorbent fibrous granules comprising:
- c) mixing hydrophobic non-self associating raw cotton sorbent fibers with a binding agent, said binding agent constitutes from about 0.5 to about 70 percent by weight of said granules, heating and extruding the mixture through an extruder to solidify the mixture;
- d) cutting the extrudate once extruded to form granules having an average diameter in a range from about 1 to about 7 cm, said granules having a density in a range from about 0.03 to 0.1 grams per cubic centimeter, said granules characterized in that they exhibit a sorbency ratio in a range from about 7 to about 30.
