▎ 摘　　要

NOVELTY - A tire is thermally decomposed, to obtain coal. The coal is ground, to obtain fine particulate. The fine particulate is mixed with transition metal-based catalyst and heated, to obtain carbon nanomaterial. USE - Production of carbon nanomaterial e.g. graphene, carbon nanoparticles (claimed), nano-dendrites, nano-hexacones, nanospheres, nano-donuts, nanoparticles and nanorods. Uses include but are not limited to nano-electronics, fuel cells, hydrogen accumulators, reinforcing and membrane materials, thermal insulators, carrier for heterogeneous electro-catalysts, lubricant additives, solar cells and lithium-ion batteries. ADVANTAGE - The carbon nanomaterial is economically produced by a simple process, using waste tire. The safe and sustainable power resources are economically formed using the carbon nanomaterial. DESCRIPTION OF DRAWING(S) - The drawing shows a view explaining the process flow of method for producing carbon nanomaterial. Primary thermal unit (1) Grinder (2) Sieve (3) Secondary thermal unit (4)
