Claim:
1. A hydrocarbon conversion method comprising: exposing a first pyrolysis feed in a first pyrolysis reactor to a peak pyrolysis gas temperature in the range of from 1540° C. to 2200° C., a pressure ≧44 psig, and a residence time in the range of from 0.004 seconds to 0.050 seconds to produce a first reactor product having a C exposing a second pyrolysis feed in a second pyrolysis reactor to a peak pyrolysis gas temperature ≧1400.0° C. to produce a second reactor product having ≧0.5 wt % methane based on the weight of the second reactor product, wherein the second pyrolysis feed has a hydrogen content <14.0 wt % based on the weight of hydrocarbons in the second pyrolysis feed; separating at least a portion of the surplus hydrogen from at least a portion of the first reactor product, wherein the second pyrolysis feed comprises at least a portion of the separated surplus hydrogen; and separating methane from at least a portion of the second reactor product, wherein the first pyrolysis feed comprises at least a portion of the separated methane.
