| This thesis presents synthesis, characterization and catalytic testing of metal incorporated MCM-41 catalysts for hydrodesulfurization. Co, Ni, and Mo are incorporated in the MCM-41 with Si/Co = 50, S1/Ni = 50, Si/Mo = 10 ratios. Aluminum was also incorporated in the structure so as to increase the acidity of MCM-41 based catalysts. These catalysts were characterized by temperature programmed reduction, atomic absorption spectrometer and X-ray diffraction.; Nitrogen isotherm, pore size distribution and XRD of these catalysts are those characteristic of MCM-41 confirming that the prepared catalysts are MCM-41. Temperature programmed reduction techniques were used to find out metal interaction and incorporation in the support, which clearly indicated that metal is getting incorporated in the structure. It can be concluded from the pulse reactor results that impregnation of metal on these metal incorporated catalysts increased the activity of these catalysts. It can be also concluded from batch reactor evaluations that MCM-41 based catalysts perform better than the zeolite based catalysts. MCM-41 based catalysts have shown high conversion per metal mole as compared to commercial catalyst in batch reactor. |
