This paper present some results obtained from the research program being pursued at the Research Institute of King Fahd University of Petroleum and Minerals aimed at the development of suitable catalysts for hydrocracking of the vacuum gas oils from Arabian Light crude to obtain higher quality distillate products. The newly developed high-performance hydroprocessing catalysts are based on synth...

Bifunctional catalysts are the preferred choice for hydrocracking processes. Ideal performance is defined by quasi-instantaneous (de)hydrogenation reactions over metal sites and limited acid catalyzed side reactions, particularly secondary cracking of desired products. Although their heavily determined balance in activity between sites, spatial arrangement both functions also holds a significan...

Plastic waste management has become a pressing global issue. A viable and sustainable alternative to incineration is the conversion of polyethylene into chemicals or fuels by through hydrocracking. To improve catalytic performance during hydrocracking, bifunctional catalysts are required, in which zeolite imparts acid function, metallic function provided noble transition metal, such as nickel. ...

In this study, beta nanozeolite, ultra-stable Y zeolite (USY) and amorphous silica-alumina (ASA) were synthesized. These compounds were used as the support of hydrocracking catalyst. Ni-Mo/beta zeolite-ASA and Ni-Mo/USY zeolite-ASA catalysts were prepared by the impregnation method. The samples were characterized with X-Ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM)...

In this contribution Artificial Neural Network (ANN) modeling of the hydrocracking process is presented. The input–output data for the training and simulation phases of the network were obtained from the Tehran refinery ISOMAX unit. Different network designs were developed and their abilities were compared. Backpropagation, Elman and RBF networks were used for modeling and simulation of the hyd...
