Catalytic Cracking TRIZ Cases
- Surfactant-Modified FCC Feedstock for Biomass Oil Co-Processing
Low molecular weight non-ionic surfactants reduce droplet size in fast pyrolysis oil mixtures.
- Integrated FCC and Alkylation Process for Xylene Production
Merges FCC and alkylation units to resolve the trade-off between fuel versatility and petrochemical yield, achieving high propylene and xylene output.
- Selective Naphtha Production via Secondary Pyrolysis of Waste Oil
Separating waste oil before secondary pyrolysis reduces chlorine corrosion and boosts naphtha yield.
- Segmented Feed Distributors for FCC Riser Conversion
Segmented feed distributors inject multiple hydrocarbon streams into distinct radial zones, improving catalyst-to-feed contacting while reducing utility costs.
- Heavy Oil Catalyst Recovery via Inclined Membrane Filtration
Inclined membrane filtration recovers spent catalyst particles with less than 1 wt.% residual heavy oil, resolving plugging issues in slurry upgrade processes.
- Intergrown AEI-CHA Molecular Sieves via Hydroxyphosphono Alkali
Single-template synthesis eliminates dual-template distribution issues to improve product consistency.
- Clay-Free FCC Catalyst Using Alumina and Silica Binders
An essentially clay-free FCC catalyst uses alumina and silica binders to inhibit low melting eutectic phase formation with iron and calcium contaminants.
- Activated Carbon Adsorbent Regeneration via Light Cycle Oil Desorption
A two-vessel system regenerates spent activated carbon adsorbents using light cycle oil to recover polynuclear aromatics.
- Slurry Pumparound Section for FCC Fractionator Coking Prevention
Dual bed slurry pumparound section distributes liquid to de-superheat vapors in fluid catalytic cracking units.
- Cyclic Fixed-Bed Reactor for Light Olefins via Dry Gas Dilution
Alternating fixed-bed reactors with dry gas diluents minimize coke formation and structural damage, sustaining catalyst activity.
- SCR Catalyst Sulfation Recovery via Iron-Copper Zeolite Composite
Iron-copper zeolite composite enables SCR catalyst recovery from sulfation deactivation by generating heat for desulfation, improving NOx reduction reliability.
- PST-16 Metallophosphate Sieves for Scalable Hydrocarbon Conversion
Replacing ethylene glycol with water enables industrial scale-up of PST-16 metallophosphate molecular sieves while maintaining high framework charge densities.
