  • 2. *• Indoor outdoor carpeting• Propylene glycols for paintshousehold detergents
  • 3. * Synthesis Of Isopropanol Detergents Copolymer For Polypropylene Used in Calibration Gas Mixtures forPetrochemical Industry Environmental Emission Monitoring Trace Impurity Analyzers
  • 4. * Steam Cracking FCC (Fluid Catalytic Cracking) CatalyticDehydrogenation Oleflex UOP Catofin ABB Lummus STAR (Philips Petroleum Company) FBD-4 Snamprogetti
  • 5. * The Group VIII metals (mainly platinum with tin) Chromium oxides on alumina or zirconia Supported iron oxides, with promoters Gallium oxide as a supported orincluded in zeolite structures Copper, for the dehydrogenation of alcohols toaldehydes

  • 8. *The active metal precursor is dissolved inan aqueous or organic solution
  • 9. * Than dried and calcined catalysts werecrushed and sieved* Catalyst characterization [temperature-programmedreduction(TPR)] were performed in multipurposeapparatus(oven reactor).

  • 19. *• A not negligible homogeneous reactions contribute is observed, due tothe reactor configuration• Minimization of reactants residence time at high temperature outof the catalytic volume• Platinum shows an evident contribute in catalyst activity• Tin catalyst decreases catalyst deactivation rate• A relevant coke formation was observed in all the catalyticconfigurations• Lower temperature tests shows a very lower propane conversion, but asensible improvement in propylene selectivity
  • 20. *For your
