Molecular Sieve Catalyst TRIZ Cases
- Bimodal Porous Dealkylation Catalyst for C9+ Aromatics
A bimodal porous dealkylation catalyst resolves low conversion rates and high energy consumption by selectively dealkylating C9+ aromatics at lower temperatures.
- Lignin Demethoxylation to Biophenol via Steam Mediation
Steam mediates demethoxylation of alkylmethoxyphenols using MoP/SiO2 and HZSM-5 catalysts, avoiding coke formation and dehydroxylation.
- Hydroalkylation Catalyst Uniform Metal Distribution
Uniform hydrogenation metal distribution in hydroalkylation catalysts enhances benzene conversion and cyclohexylbenzene selectivity.
- Lewis Acid Catalyzed Para-Xylene Production from Biomass
Lewis acids mediate DMF cycloaddition to para-xylene, minimizing 2,5-hexanedione byproducts for higher yields.
- Refractory Coating Mitigates Methane Carburization
Refractory coatings reduce carbon uptake on reactor surfaces, preventing carburization during high-temperature methane conversion.
- SSZ-13 Synthesis Using Choline Cation Template
Replacing toxic benzyl trimethyl quaternary ammonium ions with low-cost choline cations reduces synthesis costs while maintaining crystal quality.
- Segmented Catalyst Layers for Dimethyl Ether Synthesis
A segmented catalyst system combines methanol synthesis and dehydration layers to produce dimethyl ether from synthesis gas.
- Fluidized Bed Reactor Dual Distributors Benzene Conversion
Separate gas distributors control mass transfer to prevent rapid methanol consumption, boosting benzene conversion above 40%.
- Ethanol Dehydration Pretreatment for Catalyst Protection
Acidic solid pretreatment converts ethanol feedstock to diethyl ether, protecting zeolitic catalysts from nitrogen impurities and extending operational life.
- Fluidized Bed Reactor Staging for Oxygenate Conversion
Staged fluidized bed reactor converts oxygenates to hydrocarbons, increasing gasoline yield without alkylation units.
