제목 | Hydrocracking of vacuum residue using unsupported NiWS dispersed catalyst |
초록 | In the conventional oil refinery processes, metal-supported catalysts are generally used. (e.g. NiMo/Al2O3, CoMo/Al2O3). However, when supported catalysts are applied to the hydrocracking process of extra-heavy oil, several problems arise. First problem of supported catalysts is a short life time, which is caused by the deactivation by sulfur or coke deposition. Secondly, problems related to mass transfer limitations occur because large size hydrocarbon molecules are too difficult to pass through micropores or mesopores in a catalyst. In this study, to overcome the problems associated with the use of supported catalysts, we used unsupported NiWS particles as a dispersed catalyst for the hydrocracking of vacuum residue (VR). We investigated the activities of NiWS dispersed catalysts in terms of total liquid and solid product yield, C5-asphaltene conversion and API gravity of the liquid product. |
