چکیده مقاله
model natural liquid consisting of benzene, toluene and xylene mixture was used to simulate materials to test the performance of Ni supported catalysts prepared by the impregnation method The catalysts were characterized by N2 adsorption desorption and NH3 TPD analysis Ni/MCM 41 was found to exhibit good performance for aromatics hydrogenation At 150 °C the time on stream was 72 and at this period of time, the saturated aromatics capacity was high degree at first 12 h TGA results show the maximum 1 2 wt% and minimum 1 0 wt% amounts of coke were deposited on Ni/HMS and Ni/MCM 41 catalysts, respectively These coke depositions follow catalysts acidity
