Methods for dehydrogenating hydrocarbons

A method for dehydrogenating hydrocarbons comprising:

• passing a hydrocarbon feed comprising one or more alkanes or alkyl aromatics into a 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 fluidized bed reactor to produce a dehydrogenated product and hydrogen, wherein the hydrogen is hydrogen gas (H2);
• contacting the hydrogen with an oxygen-rich oxygen carrier material in the fluidized bed reactor to combust the hydrogen and form an oxygen-diminished oxygen carrier material, wherein the oxygen-rich oxygen carrier material is reducible, wherein the oxygen carrier material exhibits Geldart A properties or Geldart B properties, and wherein the dehydrogenation catalyst and the oxygen-rich oxygen carrier material are separate particles;
• passing the oxygen-diminished oxygen carrier material and the dehydrogenation catalyst to a regeneration unit;
• oxidizing the oxygen-diminished oxygen carrier material in the regeneration unit to form the oxygen-rich oxygen carrier material;
• and
• passing the oxygen-rich oxygen carrier material to the fluidized bed reactor.
