Natural bitumen which is generally used for highway paving has a short life cycle, due to traffic load and drastic change of pressure and temperature. To get the appropriate physical properties of this bitumen, it is generally modified by using reactive molecules. In this study, glycerol, styrene, methyl methacrylate (MMA), hydroquinone (HQ), and C18 acrylate molecules are used as modifiers. The required...
Two supports, one prepared in our laboratory and other supplied commercially, were used to prepare CoMo and NiMo catalysts. A commercial catalyst was also used as a reference in our present investigation. These catalysts were characterized by XRD and TPR experiments. HDM, HDS, HDN and HDAsp reactions were carried out in a microreactor using a mixture of Maya crude with naphtha as feed. The deactivation...
Three different methods are applied to prepare alumina-titania binary mixed oxide supports. These supports are used to prepare catalysts for hydrotreating of Maya heavy crude. Sequential incipient wetness and co-impregnation techniques were employed for preparation of catalysts. Ammonium heptamolybdenum was used as precursor for MoO 3 . Catalysts are characterized by XRD, TPR and pore size...
