ABSTRACT:
Disclosed herein is a novel composition of matter which is prepared by subjecting at least one woodlike particle, such as a sawdust particle and preferably selected quantities of sawdust particles to a special treatment. Each particle has a cellular structure including a plurality of interconnected, generally tubular cell walls composed in part of hemicellulose that are subjected to a selectively controlled thermolytic heating above about 280.degree. C. but not above about 380.degree. C. and preferably between 300+ C. and 360.degree. C. to cause the hemicellulose to be converted to an oil-like oleophilic and hydrophobic substance on the cell walls and reduce the thickness of the cell walls to render the particle and particles oleophilic and hydrophobic. The product floats on water, absorbs oil, for absorbing hydrocarbons on the surface of water, and is an improved fuel both without and with the hydrocarbons.
