Surfactant-templating is one of the most versatile and useful techniques to implement mesoporous systems into solid materials. Various strategies based on various interactions between surfactants and solid precursors have been explored to produce new structures. Zeolites are invaluable as size- and shape-selective solid acid catalysts. Nevertheless, their micropores impose limitations on the ma...

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...

The kinetic modeling of the hydrocracking a mixture polystyrene (PS) and vacuum gasoil (VGO) over PtPd/HY catalyst has been carried out. reactions have performed in batch reactor under following conditions: 380–420 °C; 80 bar; content PS feed, 10 wt%; catalyst/feed ratio, 0.1 mass; time, 30–300 min. Different reaction networks models studied, which evolution product distribution (unconverted PS...

Second generation biofuels, especially fuels from lignocellulose biomass, which are manufactured from non-food feedstock play a key role to reduce greenhouse gas emissions and the dependency on fossil oil. The bioCRACK process represents a new biomass-to-liquid concept to generate advanced biofuel by liquid-phase pyrolysis. As liquid heat carrier vacuum gas oil (VGO), an intermediate heavy oil ...

The inner ear develops from a simple epithelial vesicle that gives rise to the sensory hair cells, neuroblasts, secretory cells and other non-sensory tissue of the inner ear. In the zebrafish embryo, sensory hair cells begin to differentiate at the anterior and posterior ends of the otic vesicle, forming two distinct and separate sensory patches or maculae. Otic neuroblasts arise from an antero...

Slurry-phase hydrocracking utilizing metal-containing oil-soluble compounds as precursors of dispersed catalysts is an effective approach for heavy oil upgrading. We propose applying metal-based p-tert-butylcalix[6]arene (TBC[6]s) organic species catalyst to enhance catalytic hydrogenation reactions involved in the upgrading vacuum gas (VGO). Co- and Ni-based TBC[6]s were synthesized characteri...

Crude-Oil-to-Chemicals (COTC) is a novel concept in the oil industry which production of base chemicals preferred over fuels. This requires an intensive integration refinery and petrochemical operations and, most cases, hydroconversion steam cracking play essential role. In present work, particularly role assessed selected COTC scenarios via simulation framework based on fundamental modeling th...
