Disclosed in one embodiment is a method for the catalytic pyrolysis of a carbonaceous material that includes contacting the carbonaceous material with a plurality of catalyst particles to produce a gas phase product and a solid phase product and separating the gas phase product from the solid phase product and the plurality of catalyst particles. The method further includes partially regenerating the plurality of catalyst particles by exposing the solid phase product and the catalyst particles to a first oxidizing condition to produce an oxidized solid phase and a partially-regenerated catalyst and cooling the partially-regenerated catalyst and a non-oxidized portion of the solid phase product. Still further, the method includes further regenerating the partially-regenerated catalyst by exposing the non-oxidized portion of the solid phase product and the partially-regenerated catalyst to a second oxidizing condition.
