Latest Patents

Wu holds a patent for the recovery of lignin, which is precipitated in high yields and at high rates from a black liquor produced by pulping wood at high temperatures and pressures with an aqueous lower aliphatic alcohol solvent. The process involves diluting the black liquor with water and an acid to create a solution with a pH of less than about 3, an alcohol content of less than about 30% by volume, and a temperature of less than about 75 degrees Celsius. The resulting precipitated lignin, when dried, takes the form of a powder that requires little or no crushing to achieve a fine uniform size suitable for use without further significant processing.
