Process for producing large surface area lignins
Abstract
Abstract THIS PROCESS IS DIRECTED TO THE USE OF WATER-IMMISCIBLE, VOLATILE ORGANIC LIQUIDS THAT HAVE A BOILING POINT ABOVE 230*F., THAT ARE NOT LIGNIN SOLVENTS AND FORM OIL-IN-WATER SYSTEMS TO REDUCE LIGNIN PARTICLE CONTACT DURING DRYING, THEREBY REDUCING COALESCENCE. SUCH ORGANIC LIQUIDS CONTEMPLATED ARE FROM THE CLASSES OF COMPOUNDS INCLUDING AROMATICS, ALIPHATICS AND CHLORINATED HYDROCARBONS WITH ALIPHATIC COMPOUNDS BEING PREFERRED. THIS PROCESS IS USEFUL IN MAKING LIGNINS HAVING EXTREMELY LARGE SURFACE AREAS, I.E., ABOVE 30 SQUARE METERS PER GRAM BY EMULSIFYING A LIGNIN SLURRY WITH A WATER-IMMISCIBLE VOLATILE ORGANIC LIQUID HAVING A BOILING POINT ABOVE ABOUT 230*F., PRIOR TO DRYING.
