Hydroisomerization of n-Heptane in a Fixed-Bed Reactor Using a Synthesized Bimetallic Type-HY Zeolite Catalyst

The synthesis of NaY-zeolite was performed hydrothermally. preparation the bifunctional catalysts achieved by loading NH4Y-zeolite with a cheap Zr metal, as second tiny amounts Pt to compose Pt-Zr/Y-zeolite catalyst. Different characterization methods (i.e., XRD, SEM, EDX, BET, and AFM) were used investigate catalyst properties. catalytic performance studied performing hydroisomerization n-heptane in gas phase at temperature 275°C atmospheric pressure fixed-bed reactor. GC-FID results products confirmed positive role enhancing features, reflected increase isomerized decrease unwanted by-products. Incorporating 1.0wt%Zr 1.0wt% significantly improved activity selectivity increased yield branched alkanes. This because addition zirconium provided an extraordinary Lewis acidity zeolite-framework structure simultaneously took advantage electronic properties metals enhance its novel features. reduced amount metal halved cost In addition, bimetallic (HY-zeolite loaded 1wt%Pt & 1wt%Zr) values 74.2, 78.8, 58.5mol% for conversion, selectivity, yield, respectively. conversion level close 2wt% Pt/HY-zeolite catalyst, while not decreased from that Zr/HY-zeolite reaching isomers catalysts.
