| Abstract: | To meet the increasing demand for propylene,it becomes increasingly urgent to develop technologies for increased propylene production.Among these technologies,propane dehydrogenation process has received greater attention.The five proven propane dehydrogenation processes for propylene production are compared and analyzed in respect of operation,heat supply,reactant dilution,operating conditions,reactor, catalyst,energy requirement and capital investment,etc.The advantages and disadvantages of each process are pointed out.It is proposed that development should focus on Cr-based catalyst based upon special features of fluidized-bed reactor and improvement of catalyst＇ s attrition resistance. |
