Abstract
Abstract A novel oil absorbent comprising substantially sugar-free, hydrophobic, oleophilic bagasse prepared by saturating with water, removing the sugar, and then drying, which will absorb oil in an amount up to about 27 times its weight. The oil saturated absorbent is useful as a fuel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
44 words
A method for absorbing oil comprising spreading on such oil an absorbent comprising about 97 weight percent oleophilic, hydrophobic substantially sugar-free bagasse and about 3 weight percent water capable of taking-up an amount of oil equalling from about 15 to 20 times its weight.
Claim 2
Independent Claim
44 words
A method for absorbing oil comprising spreading on such oil an absorbent comprising about 97 weight percent oleophilic, hydrophobic substantially sugar-free bagasse and about 3 weight percent water capable of taking-up an amount of oil equalling from about 15 to 20 times its weight.
Claim 3
Independent Claim
54 words
A method for absorbing oil comprising spreading on such oil an absorbent comprising about 97 weight percent oleophilic, hydrophobic, substantially sugar-free bagasse fibers of about 2 to 3 mm. in length and about 3 weight percent water capable of taking-up an amount of oil equal to from about 20 to 27 times its weight.
Claim 4
Independent Claim
54 words
