NOVELTY - Co-producing carbon black based on natural gas-based graphene nano-steel comprises e.g. feeding the pretreated metal copper into a molten copper liquid catalyst, opening the valve under the natural gas tank to send natural gas into the molten copper liquid catalytic converter to catalyze the production of the canine olefin particles through the porous pipe and blowing from the orifice in the copper liquid, opening the valve above the natural gas tank and send the natural gas together with corn straw powder or corn popcorn powder into the molten copper liquid catalytic converter for catalytic decomposition of natural gas to produce diamond and carbon black particles and hydrogen, blowing together with graphene and hydrogen to a cooler for cooling, cooling dust and separating, classifying and reclaiming the gas, recovering graphene nano carbon black, and then recovering graphene diamond and sending inert gas separated from gas separation tank to inert gas tank for recycling. USE - The method is useful for co-producing carbon black based on natural gas-based graphene nano-steel. ADVANTAGE - The method ensures that 60% lower than that of ordinary nano-gold and carbon black; particle size is 0.3-2 nm, and the specific surface area is more than 1000 times higher than that of ordinary nano-steel and carbon black; and has the superior properties of both graphene and nano-steel and carbon black. DETAILED DESCRIPTION - Co-producing carbon black based on natural gas-based graphene nano-steel comprises (i) feeding the pretreated metal copper into a molten copper liquid catalyst; (ii) opening the valve under the natural gas tank to send natural gas into the molten copper liquid catalytic converter to catalyze the production of the canine olefin particles through the porous pipe and blowing from the orifice in the copper liquid; (iii) opening the valve above the natural gas tank and send the natural gas together with corn straw powder or corn popcorn powder into the molten copper liquid catalytic converter for catalytic decomposition of natural gas to produce diamond and carbon black particles and hydrogen, blowing it together with graphene and hydrogen to a cooler for cooling; (iv) cooling dust and separating, classifying and reclaiming the gas, firstly recovering the graphene nano carbon black, and then recovering graphene diamond; (v) sending the inert gas separated from the gas separation tank to the inert gas tank for recycling; and (vi) opening the remote-monitoring center system power supply switch for remote-monitoring the full process flow and the surrounding environment.
