Catalytic Cracking TRIZ Cases
- Perforated Plate Catalyst Distribution in Counter-Current Reactors
A perforated plate distributor evens catalyst flow in a counter-current reactor, improving contact time control and light olefins yield.
- Catalytic Cracking Regenerator Control for Low-Coke Aromatics
Lower regenerator temperatures and intermediate-pore zeolites help low-coke cracking feeds boost aromatics and naphtha octane without energy imbalance.
- Small-Pore Zeolite Pyrolysis for Low-Aromatic Olefin Recovery
Small-pore zeolite pyrolysis converts waste-derived feedstocks to ethylene and propylene while suppressing aromatics and easing purification.
- Light Naphtha Cyclization Before FCC for Higher Olefin Yield
Converting light naphtha paraffins into naphthenes before FCC improves reactivity and raises light olefin and gasoline blendstock yield.
- Fluidized Bed Aromatization for High p-Xylene and Autothermal Balance
Coupled naphtha-methanol aromatization uses cascade reactions and in-situ heat to raise p-xylene selectivity while cutting reforming energy use.
- Inductive Catalytic Cracking of Crude Oil With Low Coke Yield
Magnetic induction heats a susceptor-based catalytic cracker to convert crude-derived distillate into light olefins and BTX with lower energy use and coke.
- Renewable Mono-Methyl Alkylbenzene Process for High Linearity
Natural oils are converted through selective cracking, hydroisomerization, and adsorption to make low-carbon mono-methyl alkylbenzenes with 90-92% linearity.
- Mesoporous Pseudo-Boehmite for Heavy Oil Diffusion and Low Coke Yield
Controlled aging and hydroxyl regulation create mesoporous pseudo-boehmite that improves heavy oil diffusion, lowers coke yield, and preserves catalyst strength.
- Pseudo Solid State Zeolite Crystallization for Mesoporous FCC Catalysts
Reducing water in zeolite crystallization raises solids loading, adds mesoporosity, and cuts energy use in FCC catalyst production.
- Dividing Wall Column Fractionation for Olefin FCC Feed
A dividing wall column creates aromatics-free light naphtha for FCC olefin production while cutting energy use, footprint, and fractionation complexity.
- Oxygen-Fired FCC Regenerator With Flue Gas Recycle for CO2 Capture
Using oxygen firing and flue gas recycle, this FCC regenerator raises CO2 concentration and cuts capture energy by reducing nitrogen dilution.
- FCC Renewable Oil Feed Cooling to Prevent Coking and Clogging
A cooled renewable oil feed line keeps pyrolysis oil below 100°C before FCC entry, reducing polymerization, coking, and plugging.
- FCC Reactor Severity Control for Volume Gain Prediction
A neural network predicts FCC volume gain from feed and product volumes, then adjusts reactor severity to raise yield within operating constraints.
- Paraffin Dehydrogenation Feed Purification Using X-Zeolite Beds
X-zeolite and 5A adsorbent beds strip oxygenates, aromatics, and other poisons from renewable paraffins before dehydrogenation.
- Catalyst Regeneration Bypass Flow for Halogen Vent Gas Control
Splitting spent catalyst into bypass and adsorption streams cuts halogen-containing vent gas while maintaining regeneration throughput.
- FCC Catalyst Composition for Light Olefins and Aromatic Gasoline
A high-ZSM-5 FCC catalyst in a single riser boosts light olefins and aromatic gasoline while improving hydrogen distribution.
- Lateral Catalyst Conduit Fluidization for Stable Pressure Drop
Internal nozzles jet a fluidizing agent into spent catalyst in lateral FCC conduits to prevent settling, preserve pressure drop, and sustain circulation.
- FCC Regenerator Injection of Pyrolysis Oil for Catalyst Regeneration
Injecting biomass-derived pyrolysis oil into the FCC regenerator burns with coke to raise regenerator temperature and preserve product sulfur quality.
- Naphtha Aromatization Reactors Using HZSM-5 for Para-Xylene Yield
Metal-modified HZSM-5 in staged aromatization reactors converts naphtha and light alkanes into aromatics with higher para-xylene content and lower energy use.
