Pyrolytic reactor and method of using

A method to produce an alkyne, comprising:

• introducing a fuel and an oxidizer into a fuel injection zone;
• combusting the fuel and the oxidizer in a combustion zone to create a carrier gas stream;
• accelerating the carrier gas stream to supersonic speed in an expansion zone;
• injecting a feedstock material into a feedstock injection zone using at least a first plurality of injection nozzles and a second plurality of injection nozzles, the first plurality of injection nozzles being arranged annularly on a first transverse plane of the feedstock injection zone and the second plurality of injection nozzles being arranged annularly on a second transverse plane of the feedstock injection zone;
• transitioning the carrier gas stream from supersonic speed to subsonic speed to create a shockwave in a reaction zone, the reaction zone being directly connected to the feedstock injection zone and the shockwave being created adjacent to the feedstock injection zone;
• and
• simultaneously mixing and reacting the carrier gas stream and the feedstock material to form the alkyne, the shockwave helping to mix the carrier gas stream and the feedstock material.
