  Seminar: Utilization of C5-C6 Refinery Streams Guide: Dr. V. V. MahajaniAny hydrocarbon mixture can be burned to deliver energy but utilizing it for synthesis of petrochemicals is good upgradation. Refinery C5- C6 streams value addition is possible by separating and utilizing them as feed stock for valuable chemicals like ethers, ethylene, propylene, alcohols, alkylates, aldehydes, synthetic rubber, resins which have value as well as demand. As an extreme operating condition, a petrochemical refinery instead of petroleum refinery is profitable option in the markets where gasoline demand is on lower side.-----------------------------------------------------------------------------------------------------------------------------------------------Thesis: Theoretical and experimental studies in solid-liquid expanded bed.Guide: Dr. A. B. PanditLiquid–solid fluidized beds are used in chemical industry, hydrometallurgy, food technology, and biochemical processing and water treatment. The successful scale up, design and operation of liquid fluidized beds mainly depend on the accurate prediction of the behavior and features of the system, such as phase holdups and their distributions, flow patterns, and mixing levels of the individual phases. The specific objectives of this study were: (1) to measure the axial solid phase holdup profiles and calculate the axial solid phase dispersion coefficients, (2) to calculate liquid phase axial dispersion coefficients by using pulse injection technique and RTD analysis, (3) to investigate the effects of superficial velocity, bed height (inventory), and size distribution on the solid phase holdup and liquid mixing.
