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

A process for creating a master batch comprising a plurality of hemp char particles and at least one polymer comprising:

• carbonizing a portion of a hemp material, said hemp material comprising hemp hurd and hemp fibers in a furnace, said furnace being flushed with nitrogen and then heated to a temperature of greater than 1100° C.;
• wherein the temperature of greater than 1100° C. is held for at least 60 minutes;
• maintaining nitrogen flow 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 char particles having an irregular polyhedron shape by air jet milling or ball milling;
• combining the char particles with the at least one polymer, wherein the ratio of char particles to polymer is between 10:90 and 50:50;
• and
• mixing the at least one polymer and the char particles to form the master batch.

A process of forming a plurality of charred hemp particles having more than 50% of particles formed between 1 and 2 microns in size comprising:

• drying cut hemp stalk on a field for a period of less than 7 days, said hemp stalk comprising hemp hurd and hemp fibers;
• pyrolyzing the dried hemp stalk at a temperature of greater than 1100° C. to create a char;
• adding the char to a grinding vessel and mechanically grinding the char for a period of between 1 and 16 hours by grinding, air jet milling, or ball milling the char to form a ground char having an irregular polyhedron shape;
• 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.
