▎ 摘　　要

NOVELTY - Gas splitter comprises a hollow shaft (1), gas divider main body (4) and the cooling sleeve (5), are respectively provided with a plurality of air outlet hole (2) and at least one air inlet hole on the upper surface of the gas diverter main body and each air inlet are respectively connected with a hollow shaft extending upwards. The upper end of the hollow shaft is connected with the air source. The periphery of the gas diverter main body is provided with a cooling sleeve are respectively provided with at least one cooling gas inlet (3) and at least one cooling gas outlet form the gas divider for preparing graphene or other elemental carbon on the cooling sleeve. USE - The gas splitter is useful for preparing graphene or other elemental carbon. ADVANTAGE - The gas splitter has simple structure and is suitable for in large range production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of gas splitter is useful for preparing graphene or other elemental carbon.
