1. A system comprising:
an induction-heating catalyst source evaporator coupled to a reactor via a first stream comprising catalyst gas such that the reactor receives the first stream from the catalyst source evaporator,
wherein the reactor has a throughput gas hourly space velocity in the range of about 25,000 h−1 to about 100,000 h−1;
a hydrocarbon source coupled to the reactor via a second stream comprising hydrocarbon gas such that the reactor receives the second stream from the hydrocarbon source downstream of the first stream;
a heat source within the reactor from an exothermic condensation of the catalyst gas to catalyst liquid;
a cooling column coupled to the reactor via a third stream comprising hydrogen, the catalyst liquid, solid carbon, catalyst gas, and unreacted hydrocarbon gas such that the cooling column receives the third stream from the reactor;
wherein the cooling column has effluent streams that include (a) a fourth stream that comprises hydrogen and catalyst gas coupled to a first separator, such that the first separator receives the fourth stream from the cooling column and (b) a fifth stream that comprises catalyst liquid coupled to the catalyst source evaporator, such that the catalyst source evaporator receives the fifth stream from the cooling column for recycling the catalyst liquid.
