AbstractThe Hydroisomerization and Hydrocracking of n-Heptane was carried out in a
packed bed plug-flow zeolitic catalytic membrane reactor at a constant pressure
of (100 kpa).Material was encapsulated by trimetallic 1% (Pt-Ni-Co). The
structural and textural features for encapsulated nanoporous MCM-48 were
studied by X-ray diffraction, scanning electron microscopy (SEM), EDAX,
nitrogen adsorption-desorption (BET) and FTIR. The characterizations were
carried out before and after loading.
The results show that the catalytic activity evaluation in a membrane reactor
revealed that trimetallic 1 % (Pt-Ni-Co)/MCM-48 catalyst possess a high activity
for conversion of n-heptane around (83%) at 400 ºC with a maximum selectivity
around (65%) at 325 ºC.
