Title:
CARBON NANOTUBE PREPARATION DEVICE AND METHOD USING SPARK-IGNITION DUAL-FUEL ENGINE
Document Type and Number:
WIPO Patent Application WO/2022/166175
Kind Code:
A1
Abstract:
A carbon nanotube preparation device using a spark-ignition dual-fuel engine, the device comprising a natural gas storage cylinder (1), a gasoline tank (6) and a dual-fuel engine, wherein natural gas is ejected by using a gas intake passage and mixed with fresh air, and is then injected into an air cylinder (21); gasoline pre-mixed with catalyst oil-soluble ferric oxide nanoparticles is injected into the air cylinder (21) in a direct injection manner; after the two fuels enter the air cylinder (21), a combustible gas mixture is ignited in a spark ignition manner; and after a reaction in the air cylinder, a generated carbon nanotube is discharged out of the air cylinder (21) together with waste gas, and the waste gas passes through a carbon nanotube catcher (16) to collect the carbon nanotube and recover some iron nanoparticles, which are generated by means of reduction and have not participated in a catalytic reaction. The device further comprises an ECU, which is used for controlling an engine throttle valve (5), a gasoline injector (20), a gas injection valve (4), a spark plug (22) and an EGR valve (15), such that the internal temperature of the air cylinder (21) of the engine, the equivalence ratio and the reaction time can meet the optimal conditions for the growth of a carbon nanotube, thereby realizing continuous mass production of high-purity carbon nanotubes. Further provided is a carbon nanotube preparation method using a spark-ignition dual-fuel engine.
