The γ-Al2O3 supported CoNiMo tri-metallic catalysts were synthesized by four different procedures involving the variation in metal impregnation sequence. The catalysts were characterized using XRD, BET, HR-TEM, H2-TPR, Raman, and CO chemisorption techniques. All catalysts were tested for the hydrotreating of bitumen-derived heavy gas oil in a continuous fixed bed reactor operating at typical industrial...
The mesoporous alumina materials having different textural properties were synthesized by modifying the procedures mentioned in literature. Pluronic P-123 was used as structure directing agent (SDA) and aluminum isopropoxide was used as precursor for aluminum. The materials were characterized using N2 adsorption–desorption isotherms (BET), X-ray diffraction, FTIR and high resolution-TEM (HRTEM). BET,...
Large pore, high surface area mesoporous zirconia was synthesized using P123 as structure directing agent and was used as support material for hydrotreating of heavy gas oil. The mesoporous zirconia supported NiMo hydrotreating catalyst was prepared with and without EDTA via incipient wetness impregnation method. The structural characteristics of catalysts were measured by X-ray diffraction (XRD),...
