Reactor for non-oxidative direct conversion of methane and method for preparing ethylene and aromatic compound by using same

A nonoxidative methane direct converting reactor, comprising:

• an inlet through which a methane-containing supply is introduced;
• a reaction unit reacting the methane-containing supply introduced from the inlet to produce an ethylene and aromatic compound-containing product;
• and
• an outlet through which the ethylene and aromatic compound-containing product produced from the reaction unit is discharged, wherein the reaction unit is divided into:
• a first reaction zone unit producing acetylene by reaction of the methane-containing supply introduced from the inlet;
• and
• a second reaction zone unit hydrogenating the acetylene produced from the first reaction zone unit to produce ethylene and an aromatic compound, wherein a carbon layer is formed on inner circumferential surfaces of the first reaction zone unit and the second reaction zone unit, and the second reaction zone unit, on which the carbon layer is formed, has a metal compound supported on the carbon layer.
