Abstract
This invention relates to a process for converting acyclic C5 hydrocarbons to cyclopentadiene in a reactor system, wherein the process comprises a reaction interval comprising: cyclically providing to the reactor system a feedstock comprising acyclic C5 hydrocarbons; contacting the feedstock and with a particulate material comprising a catalyst material in a first reaction zone under reaction conditions to convert at least a portion of the acyclic C5 hydrocarbons to a first effluent comprising cyclopentadiene; and a reheating interval comprising: cyclically halting the feedstock to the first reaction zone; and providing a reheating gas to the first reaction zone to reheat the particulate material.
