Catalytic Cracking TRIZ Cases
- Regenerating Coked Upgrading Agent for High Syngas Yield
Two-stage regeneration with controlled oxygen partial pressure converts petroleum coke byproduct into valuable syngas.
- Doped Silica-Alumina Catalyst for Hydrocracking
Optimized pore architecture resolves the trade-off between catalytic activity and selectivity in hydrocracking processes.
- Phosphorous Modified ZSM-5 Catalyst for Propylene Yield
Phosphorous modified sub-micron ZSM-5 zeolite increases propylene yields while maintaining gasoline output in fluid catalytic cracking.
- BTX Production via Catalytic Cracking and Aromatic Ring Opening
Segmenting hydrocarbon feed into gasoline and cycle oil fractions allows optimized aromatic ring opening to boost BTX yield beyond theoretical limits.
- Monocyclic Aromatic Hydrocarbon Production Vibration Control
Segmenting feedstock introduction suppresses pipe vibration while maintaining efficient heat recovery in aromatic production.
- Differential Pressure Gauge Monitoring for FCC Catalyst Injection
Differential pressure gauges monitor filter pressure differentials in fluidized catalytic cracking units to detect blockages and reduce problem detection time.
- FCC Unit Heat Balance via Aromatic Complex Integration
Integrating an FCC unit with an aromatic complex recycles coking cuts to preheat feedstock, resolving heat balance deficits from low coke production.
