Abstract

A continuous hydrocarbon pyrolysis process to produce hydrogen gas and carbon includes exposing a hydrocarbon feedstock to an oxygen depleted combustion gas within a hydrocarbon pyrolysis zone. A combustor produces the combustion gas at a temperature greater than 2,400° C. The hydrocarbon feedstock and combustion gas have a residence time within the hydrocarbon pyrolysis zone less than 30 seconds to cause pyrolysis of the hydrocarbon feedstock and produce gas comprising hydrogen and solid particles comprising carbon. The gas and solid particles exit the hydrocarbon pyrolysis zone at a temperature greater than 1,200° C. A heat exchanger cools the gas and solid particles to a temperature less than 200° C. A gas absorber removes unwanted gas molecules from the gas and produce H₂ containing gas having an H₂ concentration greater than 80 vol. % H₂. The H₂ containing gas is continuously introduced to a H₂ consuming facility.
