LIGNIN-SOLIDS COMPOSITIONS

摘要

A lignin-solids composition comprising surface modified solids wherein said surface modified solids have adsorbed thereon thermally treated lignin. A method for preparing a lignin-solids composition comprising thermally treating a mixture of lignin and solids in the presence of oxygen for 1 to 3 hours and at a temperature in the range of 140.degree. to 170.degree.C to produce thermally treated lignin and to allow the thermally treated lignin to adsorb onto the surface of the solids.
