High temperature bio-char carbonization and micron grinding and classification for inclusion into master batch polymerization

A process for creating a masterbatch comprising a plurality of hemp char particles and a polymer comprising:

• carbonizing a portion of a hemp material in a furnace, said portion of hemp material comprising hemp fiber and hurd, said furnace being flushed with nitrogen and then heated to greater than 1100° C.;
• wherein the temperature greater than 1100° C. is held for at least 60 minutes;
• nitrogen flow is maintained over the at least 60 minutes to maintain a low oxygen environment to create a char;
• removing the char from the furnace and allowing it to cool;
• milling the char by a milling process for a period sufficient to reduce the char into a plurality of particles having average particle size of less than 2 microns to create char particles of less than 2 microns;
• combining the char particles having an average particle size of less than 2 microns with the polymer, wherein the ratio of char particles to polymer is between 10:90 and 50:50;
• and mixing the polymer and the char particles to form the masterbatch.

A process of forming charred hemp particles of less than 2 micron in size, comprising:

• drying cut hemp stalk on a field for a period of less than 7 days, said hemp stalk comprising fiber and hurd;
• pyrolyzing the dried hemp stalk at 1100°-1500° Celsius to create a char;
• adding the char to a grinding vessel and grinding the char for a period of 1 to 16 hours;
• screening the ground char with a 2 micron screen to create a screened char of less than 2 microns;
• and capturing the screened char of less than 2 microns.
