Catalytic Cracking TRIZ Cases
- Dual Riser FCC System Olefin Yield Optimization
Segregating light and heavy feeds into independent risers resolves heat balance constraints while boosting olefin production.
- Hydrocracking Catalyst Carbonaceous Substance Selectivity
A hydrocracking catalyst uses a carbonaceous substance to balance activity and suppress excessive cracking.
- FCC Riser Sulfur Reduction via Carbon Monoxide Reducing Agent
Introducing carbon monoxide into the riser reactor reduces sulfur content by over 50% without hydrotreating capital costs or octane loss.
- Supported Chromium II Catalyst for Alkane Conversion
A supported chromium II catalyst converts alkane reactants into lower and higher molecular weight aliphatic hydrocarbons.
- Electrically Conductive Fluidized Bed for Endothermic Cracking
Passing electric current through conductive particles heats the fluidized bed to 500-850°C for catalytic cracking.
- Magnesium-Modified Y Zeolite for Heavy Oil Cracking
Magnesium-modified ultra-stable rare earth Y zeolite resolves ammonium nitrogen pollution by replacing conventional salts with dispersing pre-exchange.
- Mixed Metal Oxide Additive for FCC Catalyst Metal Trapping
Magnesium-aluminum mixed metal oxide additives capture iron, nickel, and vanadium to protect fluid catalytic cracking catalysts from deactivation.
- Fluid Catalytic Cracking Oligomerate Process for Propylene Yield
Oligomerization system with FCC zone cracks distillate to propylene using controlled branching and boiling points.
- Olefin Oligomerization for FCC Separation Bottlenecks
Converts FCC olefins to heavier compounds via oligomerization, resolving separation difficulty from refractory paraffins in recycle streams.
