Oil is comprised of a complex mixture of hydrocarbons which can be separated into various fractions based on the boiling point by atmospheric and vacuum distillation, followed by oil processing, namely catalytic reforming, alkylation, catalytic cracking and hydroprocessing in order to alter ratios of the different fractions. Atmospheric residue (AR, initial boiling point ＞ 343°C) and vacuum residue (VR, initial boiling point ＞ 500°C) which are obtained in this process, are typically used as feed reactants of hydroprocessing as well as carbon rejection processes. In this study, an effect of alumina-supported metallic oxide catalysts on thermal decomposition of vacuum residue was investigated to improve the decomposition efficiency of vacuum residue. Metallic oxide was deposited on alumina support by impregnation. The prepared catalysts were characterized by XRD, SEM and EDX. The thermal decomposition of vacuum residue with each catalyst mixed, was studied using thermogravimetric analysis. |
