Research:Construction and Design of Heterogeneous catalyst for Carbon Source Recycle

1. Chemical Upcycling of WastePolyolefins (Postdoctoral Research)  

Designed and constructed a degradation system centered on ahigh-temperature/high-pressure batch reactor. Optimized reaction parameters(temperature: 250-300°C, pressure: 0.1-5 MPa, residence time) to enhancepolyolefin degradation efficiency (target gasoline component yield: 80wt%).  

Established a multi-technique analytical system (GC-MS for qualitativeanalysis, NMR for structural elucidation, GC for quantification, TGA forthermal stability evaluation) and developed standardized data processingprotocols.  

Developed supported metal catalysts (Zn-beta) and nano-sized catalytic systems(nano-beta). Screened optimal catalytic combinations by comparing selectivityand reaction activity.  

2. In Situ Catalyst PerformanceEvaluation System (Postdoctoral Research)

Independently designed an in situ IR diffusion kinetics measurement system forzeolite catalysts. Integrated high-temperature environments with in situ FTIRto monitor real-time dynamic changes in active sites and probe moleculeadsorption behavior, providing precise feedback for catalyst structuraloptimization.  

3. C1 Molecular Catalytic Conversion (PhD& Postdoctoral Research)  

 Catalyst Design:Developed 2D (topological layered structure) and hierarchical pore molecularsieves (e.g., MOR, YFI types). Modified Al site distribution (controlling acidstrength gradient) and pore topology to enhance catalytic performance.  

 ReactionSystem Development: Constructed a fixed-bed reactor coupled with online GCanalysis (GC-OLT) for dimethyl ether carbonylation to methyl acetate andmethanol-to-olefins (MTO) reactions. Optimized reaction parameters(temperature: 200-600 °C, pressure: 3-10 MPa) to significantly improve catalyticactivity.  

4. Zeolite Catalyst Structure Design andReaction Performance Optimization (PhD Research)  

Synthesized novel YFI-type zeolites andexplored their applications in methanol-to-olefins and hexane crackingreactions. By tuning the Si/Al ratio (50-700) and creating meso-macroporoushierarchical structures, significantly enhanced selectivity for target products(ethylene, propylene).
