1. A hydrocarbon conversion method comprising: exposing a pyrolysis feed comprising hydrocarbons and an added diluent in a regenerative reverse-flow thermal pyrolysis reactor to thermal pyrolysis conditions at a peak pyrolysis gas temperature ≧1200.0° C., for a residence time in the range of 4 milliseconds to 50 milliseconds, and at a pressure ≧44 psig to produce a reactor product comprising C2 unsaturates and having a C3+ to C2 unsaturates weight ratio ≤0.5, wherein (i) the added diluent is added in an amount of more than zero but up to 10 wt % based on the combined weight of the hydrocarbons and the added diluent and (ii) the added diluent is one or more of H2O, CO2, and H2S.
