Nitrous Oxide Capture TRIZ Cases
- Spherical Molecular Sieve Catalyst for Low-Temperature SCR
Spherical molecular sieve catalyst composites enable selective catalytic reduction of nitrogen oxides across a wide temperature range.
- Hollow Microsphere Catalyst Support Density Reduction
Incorporating hollow mineral microspheres into a calcined catalyst support matrix reduces material density while preserving mechanical strength.
- Adsorbent Regeneration via Flow Reversal and Heat Recovery
Flow reversal purges adsorbents while heat exchangers recover thermal energy from indoor air streams to lower regeneration power requirements.
- Phosphorus-Free Cu-CHA Zeolite Synthesis via Single-Stage Crystallization
Single-stage hydrothermal crystallization produces high-copper CHA zeolites without phosphorus, eliminating contamination and reducing process complexity.
- Rhodium-Ceria Catalyst for Low-Temperature N2O Removal
Rhodium supported on ceria removes nitrous oxide emissions while maintaining thermal stability.
- SNCR in Fluidized Bed Boilers for Low Load NOx Reduction
Direct ammonia injection into the combustion zone reduces system complexity and cost while maintaining effective NOx removal across varying load conditions.
- Iron-Modified Molecular Sieve SCR Catalyst for NOx Conversion
Incorporating iron salt into a promoter metal-molecular sieve catalyst composition forms active iron species on the surface.
- Organotemplate-Free Zeolite Beta Synthesis via Seed Crystals
Seed crystals initiate crystallization of zeolitic materials with a BEA framework structure under mild hydrothermal conditions.
- Lean NOx Adsorber Catalyst Low-Temperature Performance
Segmented lean NOx adsorber catalyst layers combine platinum-palladium oxidation with alkaline earth storage.
- Nitrous Oxide Face Mask with Switching Valves
A face mask arrangement uses switching means to alternate inhalation of nitrous oxide and oxygen mixtures for patient-controlled administration.
- Catalyst Device for Formaldehyde Removal
Cryptomelane manganese oxide and cerium oxide convert formaldehyde to carbon dioxide, solving desorption issues found in activated carbon systems.
- Composite Catalyst for NOx Reduction
Amorphous mesoporous metal oxide combined with zeolitic material enhances catalytic activity, resolving high-temperature stability trade-offs.
