Preparation and Characterization of Nanoporous Zeolitic Membranes for Catalytic Applications

Abstract

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