1. A method for dehydrogenating hydrocarbons comprising:
passing a hydrocarbon feed comprising one or more alkanes or alkyl aromatics into a first fluidized bed reactor, wherein at least 95 wt. % of the hydrocarbon feed has an atmospheric boiling point of less than or equal to 300° C.;
contacting the hydrocarbon feed with a dehydrogenation catalyst in the first fluidized bed reactor to produce a dehydrogenation effluent comprising hydrogen;
passing the dehydrogenation effluent to a second fluidized bed reactor, wherein the second fluidized bed reactor comprises an oxygen-rich oxygen carrier material, and wherein the oxygen-rich oxygen carrier is reducible;
contacting the hydrogen of the dehydrogenation effluent with the oxygen-rich oxygen carrier material to combust at least a portion of the hydrogen, produce a combustion effluent, and form an oxygen-diminished oxygen carrier material;
passing the oxygen-diminished oxygen carrier material to a first regeneration unit;
oxidizing the oxygen-diminished oxygen carrier material in the first regeneration unit to form the oxygen-rich oxygen carrier material; and
passing the oxygen-rich oxygen carrier material from the first regeneration unit to the second fluidized bed reactor.
