Catalytic Cracking of C4 Olefin to Propylene and Ethylene Technology (OCC)

1. High weight hourly space velocity: OCC-100 catalyst can be operated at high weight hourly space velocity.
2. Reactor size can be reduced dramatically by OCC technology so that investment and operating costs can be minimized.
3. Extraordinary stability: catalyst regeneration cycle time can reach 20 days. According to the actual conditions, regeneration cycle time can be adjusted from 3 to 20 days.
4. Good economic efficiency and low energy consumption: without any dilute in the feedstock and with the integration of high efficiency heat exchanger, OCC technology can reduce the plants energy consumption, the size of reactors and piping also can be reduced.
5. Good feedstock flexibility: C4/C5 olefins from steam crackers, refineries or MTO plants are all favorable feedstock for OCC process. OCC catalyst has good resistance to the impurities such as diolefins, sulfides and nitrogenous compounds.
6. OCC process uses adiabatic fixed bed reactor with simple structure and low investment.
