Catalyst Activation/Preparation TRIZ Cases
- Plasmonic Cu/Zn Photocatalysis for Selective Methanol Production
Intense light and pressure drive CO2 hydrogenation over plasmonic Cu/Zn nanoparticles, delivering over 80 mol% methanol selectivity.
- Extruded Titania-Alumina Catalyst for Heavy-Oil Demetallation
A defined pore structure helps extruded catalysts resist metal deposition while improving demetallation, sulfur conversion, and stability.
- Six-Lobe Star Ceramic Catalyst Support for Surface Area and Pressure Drop
Specific lobe geometry increases catalyst-support surface area while limiting pressure drop and preserving packed-bed strength.
- Ferrite Catalyst Dilution in Butadiene Reactors for Hot Spot Control
This case shows how catalyst-to-diluent mixing stabilizes butadiene production by controlling hot spot movement, exotherm, and energy use.
- g-C3N4@CuO/MgAl2O4 Nanocomposite Catalysis for NaBH4 Hydrogen Generation
This case uses g-C3N4@CuO/MgAl2O4 to catalyze NaBH4 hydrolysis, reaching 1300–1500 mL/min/g hydrogen generation.
- Hydrocyclone Catalyst Classification for Consistent Olefin Polymerization
Hydrocyclone separation and spray drying modify catalyst particles, reducing fines and improving polymer homogeneity in reactors.
- Supported Cobalt Sulfide Catalysts for Moderate-Pressure Acids and Esters
This gas-phase process converts cobalt thiocyanate into a supported cobalt sulfide catalyst for selective acids and esters.
- 3R MoS2–MoO3 Composite Catalysts for Hydrogen Evolution
Micronized MoS2 falls short on hydrogen evolution; a 3R MoS2–MoO3 composite tunes phase ratios through low-temperature sulfurization.
- Graphitic C3N4–MnO2–MgAl2O4 Nanocomposite for Rapid Hydrogen Generation
Graphitic C3N4, MnO2, and MgAl2O4 form a nanocomposite catalyst for fast, cost-effective hydrogen generation from NaBH4.
- Nickel-Molybdenum Catalyst Ratio for Selective Gasoline Hydrogenation
The porous alumina-supported NiMo catalyst uses a 2.5–3.0 molar ratio to improve diolefin selectivity, reduce gum, and convert mercaptans.
- Supported Metal Nanoparticle Catalysts with Dual-Reductant Growth Control
A strong and weak reducing-agent pair separates nucleation from growth for uniform monometallic or bimetallic supported catalysts.
- Porous PbTiO3/TiO2/Zn2Ti3O8 Nanocomposite Via Sol-Gel Combustion
This case uses glycine-assisted sol-gel combustion to form porous PbTiO3/TiO2/Zn2Ti3O8 with controlled phases and particle sizes.
- Spherical Composite Catalyst for Ammonia-Efficient Acrylonitrile Production
Staged calcining creates uniform crystal phases for efficient ammonia use and higher acrylonitrile production.
- Sheathed Platinum-Rhodium Grid Catalyst Wire for Rhodium Needle Reduction
A radially layered platinum-rhodium wire lowers rhodium needle formation while preserving activity and NO2 selectivity.
- Powder Catalyst Coating for Aluminum Heat Exchanger Cavities
A low-temperature adhesive and barrier layer enables uniform catalyst coating in narrow aluminum cavities without intermetallic damage.
