Catalytic Cracking TRIZ Cases
- Fluidized Catalytic Cracking Catalyst Regeneration With Bio-Based Fuel
Bio-based liquid fuel and oxygen-containing gas burn coke from spent catalyst, reducing fossil energy use and carbon emissions in FCC regeneration.
- Low Sulfur Marine Fuel Oil Blends for Asphaltene Stability
Pre-blending asphaltenic resid with aromatic cracked stock supports stable marine fuel blends below 0.5% sulfur without proprietary additives.
- Plastic Waste Catalytic Pyrolysis With Alkane Oxidation Integration
Combining alkane oxidation with catalytic pyrolysis turns plastic waste and light hydrocarbons into olefins and aromatics while increasing process capacity.
- Resid FCC Catalyst Composition for Heavy-Oil Diffusion Control
Hierarchical pores improve diffusion of large resid-oil molecules while the catalyst delivers high conversion with less coke and dry gas.
- Mesoporous Y Zeolite Catalyst for FCC Bottoms Cracking
Small zeolite pores restrict heavy hydrocarbons in FCC units; mesoporous Y zeolite improves access and supports gasoline and light cycle oil yields.
- FCC Catalyst Regeneration With Staged Hot Stripping
Hot regenerated catalyst returns to the stripper to improve FCC stripping and reduce coke, sulfur, nitrogen, SOx, and NOx during staged regeneration.
- Hierarchical RFCC Catalyst Composition for Low Coke and Dry Gas
A hierarchical alumina-silica matrix with rare-earth Y zeolite increases porosity while limiting coke and dry gas in resid oil cracking.
- Biorenewable Kerosene From Hydrotreating Without Hydroisomerization
Hydrotreating biorenewable oils without hydroisomerization produces n-paraffin kerosene while avoiding catalyst deactivation and aromatics.
- Nickel Oxide–Alumina Nanocatalysts for Heavy Oil Upgrading
Nickel oxide nanoparticles on alumina enhance asphaltene sorption, supporting heavy oil cracking at lower reaction temperatures and pressures.
- Side-Orifice Feed Distributor for Uniform FCC Riser Mixing
Side and end orifice clusters spread hydrocarbon feed across the FCC riser, improving catalyst mixing and conversion with less coke.
- Paraffin Separation With Light Ends Splitting to Cut Utility Duties
A heat-integrated paraffin separation sequence removes C4+ hydrocarbons early to reduce utility duties and improve ethylene recovery.
- Monolithic Fe-Co Catalyst Coating for NH3 Conversion in FCC Flue Gas
A porous Fe-Co catalyst coating converts NH3 in FCC flue gas to curb ammonia-nitrogen excess and downstream salt deposition.
- Hydroconversion Catalyst Sulfidation and Pre-Carbonization for Coke Control
Pre-sulfide and carbonize hydroconversion catalysts to limit premature coke and gum formation.
- Low-Carbon Methanol Co-Production Using Existing Refinery Assets
This case uses syngas and existing methanol or FCC infrastructure to scale certifiable low-carbon fuels without dedicated facilities.
- Headerless Catalyst Cooler Design for FCC Heat Control
A central supply tube and coaxial heat removal conduit reduce complexity while improving catalyst cooling and heat transfer.
- Modified Zeolite Catalyst for Naphtha Cracking Coke and Heat Balance
Surface-modified alumina on ZSM-5 helps manage coke formation while regeneration sustains heat balance and increases olefin and BTX yields.
- Hydrodeoxygenated Bio-Oil Fractionation in Existing Refineries
Hydrodeoxygenated bio-oil joins crude oil fractionation in existing refinery units.
- Manganese-Modified Alumina Catalyst for Nickel-Resistant Cracking
This catalyst combines two aluminas with manganese to resist nickel pollution, lowering hydrogen-to-methane, dry gas, and coke yields.
- Fluidized Bed Reactor Cracking with Continuous Coke Regeneration
A fluidized bed reactor heats light hydrocarbons and regenerated catalyst, then combusts coke to sustain conversion and reduce deactivation.
