title = "Oil soluble dispersed catalysts for slurry phase hydrocracking of heavy VGO",
abstract = "The promotional effects of dispersed co-catalysts on hydrocracking of vacuum gas oil (VGO) were studied using oil soluble Mo, Fe and Co based materials. Experiments were conducted in a batch autoclave reactor at 4 MPa and 420 °C, with and without the presence of a commercial first-stage hydrocracking W-Ni/Al2O3-SiO2 catalyst. The dispersed metal catalysts enhanced the hydrogenation activity and minimized the amount of coke formation. The lowest coke formation was obtained by using only 500 ppm of dispersed catalysts in the feed. Co and Mo based catalysts showed lower coke formation than Fe catalyst. The additional of only 500 ppm of Co/Mo decreased the coke from 2.5 to 0.9 wt% during the thermal run. The addition of dispersed catalyst together with the solid catalyst also exhibited similar decrease of coke formation. The presence of dispersed catalysts also enhanced the percentage of naphtha and decreased the heavy VGO fraction when supported metal was used. A kinetic model was developed based on the experimental data for the catalytic test (dispersed + solid). The activation energy of VGO cracking forming distillate requires the least activation energy (1.477 kcal/mol) as compared to the other competing reactions. Therefore, VGO will most likely crack to distillate then distillate will crack to naphtha and naphtha will be cracked to gases.",
