Claim:
1. A hydrocarbon conversion method comprising: a) providing a weight based rate (WT1) of a first hydrocarbon feed having a carbon parameter (CHC1) and a hydrogen parameter (HHC1), where the hydrogen parameter (HHC1) is <14.0 wt % of the first hydrocarbon feed; b) providing a weight based rate (WT2) of a second hydrocarbon feed having a carbon parameter (CHC2) and a hydrogen parameter (HHC2), where the hydrogen parameter (HHC2) is ≧14.0 wt % of the second hydrocarbon feed; c) providing a weight based rate (WTD) of a hydrogen containing stream having a hydrogen gas content (HH2D) and a hydrocarbon content (HCD), wherein the hydrocarbon content (HCD) has a hydrocarbon hydrogen parameter (HHCD) and a hydrocarbon carbon parameter (CHCD) as a weight percent of total hydrogen containing stream; d) combining the first hydrocarbon feed and the second hydrocarbon feed and the hydrogen containing stream to form a pyrolysis feed having (i) a hydrogen parameter (HHCT) in the range of 12.0 wt % to 18.0 wt % based on the weight of the pyrolysis feed and (ii) a total atomic hydrogen to carbon ratio (HCRT) in the range of 3.0 to 15.0; and e) exposing the pyrolysis feed in a reverse-flow thermal pyrolysis reactor to high-severity pyrolysis conditions which include a peak pyrolysis gas temperature≧1540° C., a pressure≧44 psig, and a residence time in the range of 5 to 53 milliseconds, to yield an intermediate which includes hydrocarbon radicals and to produce a reactor product comprising ethylene and acetylene, wherein the reactor product has a C
