Development of Heavy Oil Hydrocracking Catalysts
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...
متن کاملPreparation for Pt-Loaded Zeolite Catalysts Using w/o Microemulsion and Their Hydrocracking Behaviors on
Pt-loaded β-type zeolite catalysts with constant Pt content (0.11 wt.%) and similar pore structure were prepared using a water-in-oil (w/o) microemulsion. The effect of Pt particle synthesis conditions using microemulsion (a type of Pt complex-forming agents and the molar ratio of complex-forming agent to Pt4+) on loaded Pt particle size was investigated. The Pt particle size of the Pt catalyst...
متن کاملFischer-Tropsch Synthesis of Hydrocarbons Using Iron-Mordenite Catalysts
Fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type SiO2/Al2O3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by X-ray powder diffraction. The adsorptionof volatile Fe(CO)5 on the support surface was carried out under vacuum at room temperature. Reduction les...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولMicroemulsion-mediated Synthesis of Nanosize Molybdenum Sulfide Coal Liquefaction Catalysts
INTRODUCTION In heterogeneous catalysis, the size of the catalyst is of considerable importance in that the extent of reaction is often inversely proportional to the particle size of the catalyst. As a consequence, various methods have been used to synthesize particles of large specific surface area for catalysis applications (1-3). Most of these methods are based on hydrocolloids (1) and aeros...
