Abstract
A fluidized bed reactor system including a fluidized bed reactor configured to receive a heated light hydrocarbon feed stream flowing upwards and a heated regenerated catalyst at a temperature sufficient to crack the heated light hydrocarbon feed stream to produce a product effluent stream containing hydrogen and spent catalyst having coke deposits, a catalyst regeneration unit operatively connected to a bottom portion of the fluidized bed reactor, the catalyst regeneration unit being configured to receive the spent catalyst flowing downwards and combust the coke deposits to produce the heated regenerated catalyst and a heated gas effluent for generating the heated light hydrocarbon feed stream, and a riser externally attached to the fluidized bed reactor and the catalyst regeneration unit, the riser being configured to receive the heated regenerated catalyst and a gas-based stream to flow the heated regenerated catalyst upwards to the fluidized bed reactor.
