| Abstract | In the present study, hydrogenation of carboxylic acid was performed in a continuous manner, using Micro Waves (MW), and a sulfide catalyst. SBA-15 supported NiMo hydrotreating catalysts were prepared by incipient wetness impregnation method and synthesized NiMo on AlSBA-15 and ZrSBA-15 in order to investigate the role of support acidity. Extrudates of the supported NiMo powders were prepared and sulfided. Octanoic acid in dodecane (10%) was introduced in the continuous flow reactor by the mean of an HPLC pump and co-feeded with hydrogen at a working pressure of 0.5 MPa, while varying the reaction parameters such as temperature and feed flow rate (0.1, 0.25, and 0.5 ml/min). Power applied to the monomodal cavity varies in the range of 15-150 W and corresponding temperature from 200-350?C. Catalysts and supports were characterized by small- and wide-angle XRD, N2-physisorption (BET, BJH), HRTEM, ICPMS, UV-vis, 27Al MAS-NMR and NH3-TPD. The result of thermal response of MW found that the extrudates of SBA-15 (with or without Al or Zr) exhibit a strong MW response. The comparison of catalytic activity shows that all SBA-15 supported NiMo catalysts exhibit the same activity but the selectivity as compared to NiMo/Al2O3 catalysts was different. |
