NICKEL CATALYTIC ACTIVITIES ON THE SUPPORTS OF SILICA AND ACTIVATED CARBON EXTRACTION FROM LOCAL RICE HUSK FOR NITROBENZENE HYDROGENATION: A COMPARATIVE STUDY

Activated carbon (RHAC) and Silica (RHSiO2) both were prepared from Rice Husk (RH) with very simple methods. These supports were used for the preparation of Ni catalyst for hydrogenation of nitrobenzene by wet impregnation and reductive deposition method. Ni/RHSiO2 and Ni/RHAC catalysts are characterized by BET, XRD, SEM, and TPR techniques. Well, dispersion of Ni on these supports shows excellent conversion of nitrobenzene to Aniline.
