Abstract
Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The conversion of hydrocarbons to hydrogen is performed in one or more pyrolysis or conversion reactors that contain a plurality of sequential fluidized beds. The fluidized beds are arranged so that the coke particles forming the fluidized bed move in a counter-current direction relative to the gas phase flow of feed (e.g., methane) and/or product (H) in the fluidized beds. By using a plurality of sequential fluidized beds, the heat transfer and management benefits of fluidized beds can be realized while also at least partially achieving the improved reaction rates that are associated with a plug flow or moving bed reactor.
