Specialization Applied catalysis and multiphase reactors in process and environmental engineering
Research Projects My current areas of research interests are:
Gas Induced Reactors
Gas induced reactor (GIR) systems provide an efficient solution to improve the performance of gas-liquid contactors which are limited by gaseous reactant mass transfer rate. GIR systems are also beneficial when a potentially toxic or costly gaseous reactant such as ozone is used for treatment of pollutants in water. A GIR is a mixed reactor in principle that has a suction effect at the liquid-gas interface due to the induced vortex at the surface. This prevents unreacted gas from escaping the reactor.
The emphasis of this project will be scale up and pilot scale application of GIRs for gas liquid systems and ozone reactions for industrial water and wastewater treatment applications.
Application of ultrasound in decomposition of toxic chemicals in water
Application of ultrasound energy in an aqueous medium leads to extreme conditions in the system. In a sonicated medium, extremely large number of submicron size bubbles is generated and collapse in a matter of microseconds. While the reaction medium stays at a mild temperature, high temperatures (in the range of 5000 K), high pressures (in the range of 1000 atm) and high cooling rates (~1010 K/s) occur inside the collapsing bubbles. Under these extreme conditions, harmful chemical compounds can be simply burnt out. In addition a large number of active chemical species are generated in the reaction medium outside the collapsing bubbles. This is also a harsh environment for chemicals to survive.
In this project we will focus on decomposition of harmful chemicals in water and mathematical modeling of the phenomena.
Application of heterogeneous catalysts in ozonation processes
Ozone (O3) is a strong oxidant that can potentially convert any hydrocarbon into CO2 and water. It has been used successfully in a large number of water and wastewater treatment processes. A catalyst that can increase the speed of ozonation reactions can significantly improve the technical and economic feasibility of application of ozone.
Using solid surface bonded nonpolar catalysts can improve performance of ozonation reactions by providing a suitable nonpolar medium for sorption of both ozone and pollutants and facilitating their contact and reaction. Catalysts based on long chain perfluorinated groups supported on alumina can also enhance molecular mechanism of reactions of ozone rather than hydroxyl radical mechanism. This makes ozone a much safer and favorable disinfection agent for water treatment purposes.
The focus of this project will be preparation, characterization and performance evaluation of ozonation catalysts.
Conversion of methane to aromatics using nano molybdenum carbide catalysts
Methane is the major constituent of natural gas and the most stable alkane. Conversion of methane to higher hydrocarbons increases the potential value of natural gas. Conversion of methane into benzene and hydrogen is a very favorable reaction from thermodynamic point of view. Promising results from this reaction have been reported in literature with catalysts of Mo supported on zeolite. Using sonochemical preparation methods it is possible to produce nano-size high dispersion catalysts of molybdenum carbide supported on zeolite. Ultrasound is a very promising method of preparing nano sized catalyst with controlled desired properties and particle size distribution. High temperature (~5000 K), pressure (~1000 atm) and extreme heating/cooling rates (~1010 K/s) in collapsing bubbles in a sonicated liquid provide energy to initiate decomposition of organometallic precursor in the bubbles leading to generation of very fine, high dispersion catalyst particles.
The focus of this project will be preparation, characterization and performance evaluation of methane dehydroaromatization catalyst produced by ultrasound method.
