Title:
PROCESSES AND SYSTEMS FOR CONVERTING HYDROCARBONS TO CYCLOPENTADIENE
Document Type and Number:
WIPO Patent Application WO/2017/078905
Kind Code:
A8
Abstract:
This invention relates to a process for converting acyclic C5 hydrocarbons to cyclopentadiene including: providing to the at least one adiabatic reaction zone a feedstock comprising acyclic C5 hydrocarbons at a temperature, Ti, wherein the at least one adiabatic reaction zone comprises a first particulate material comprising catalyst material; contacting the feedstock and the first particulate material in the at least one adiabatic reaction zone under reaction conditions to convert at least a portion of the acyclic C5 hydrocarbons to a first effluent comprising cyclopentadiene intermediates, unconverted acyclic C5 hydrocarbons, and, optionally, cyclopentadiene; heating the first effluent to a temperature, T2; providing the first effluent to the at least one diabatic reaction zone; and contacting the first effluent and a second particulate material comprising catalyst material in the at least one diabatic reaction zone under reaction conditions to convert at least a portion of the cyclopentadiene intermediates and the unconverted acyclic C5 hydrocarbons to a second effluent comprising cyclopentadiene.
