Claim Text:
1. A method for thermally decomposing gaseous hydrocarbon feedstock, comprising: heating a non-oxidative carrier gas with a heat exchanger such that the carrier gas if mixed with a volume of gaseous hydrocarbon feedstock would cause at least partial decomposition of the volume of gaseous hydrocarbon feedstock; delivering a first volume of gaseous hydrocarbon feedstock into a reaction chamber; delivering the carrier gas into the reaction chamber through one or more porous walls such that the carrier gas and the first volume of gaseous hydrocarbon feedstock mix within the reaction chamber and the carrier gas transfers heat to the first volume of gaseous hydrocarbon feedstock within the reaction chamber causing the decomposition of the first volume of gaseous hydrocarbon feedstock, wherein the decomposition reaction occurs in a substantially oxidant-free environment, and wherein the decomposition of the first volume of gaseous hydrocarbon feedstock results in a product comprising hydrogen gas and carbon substances; removing at least a first portion of the carbon substances from the reaction chamber; and delivering a portion of the first portion of the carbon substances back into the reaction chamber for use as a catalyst in a decomposition reaction of another-volume of gaseous hydrocarbon feedstock.
