Topic 3: Catalytic degradation technology for treatment of wastewater

Through earlier work in our laboratory, we have developed prorous material based catalytic nanoparticles,

which have been shown to degrade dye and  possibly other contaminants, present in wastewater, at an enhanced

rate. We have also developed a model combining transport and reaction rates to capture diffusion, adsorption and  read more »

Molecular simulations of lithium insertion/deinsertion processes in novel lithium ion battery anode materials

Metal oxides, e.g., SiOx and SnOx, and Si are regarded a prime candidate materials for high energy batteries. However, many challenges need to be addressed, including issues related to the large volume variation during the discharging/charging process, poor electrical conductivity, and  unstable solid electrolyte interphase films, which restrict its stable cycle life as well as commercial viability. Here, we will use theory to first understand the Li insertion/deinsertion process and then design silicon and SnOx nanostructures that attempts to resolve such challenges.

Process Intensification through multifunctional reactors and catalysis

The work involves identification of a gowing fine chemical and develop a process for the same. Catalyst would be identified and synthsized if required. Catalyst would be characterised and teh performance will be evaluaed and comapred with the conventional counterpart. Various strategies such as combining reaction and separation in a single unit would be explored. Kinetic modeling would be performed for the new catalyst. Modeling and simulation would be performed to comapre the same with the conventional process and bring out the added benefits offered by the porposed process.  read more »

Topic 1: Functional Nanoparticles: Experiments, modeling, simulation

Nanoparticles and their clusters show new and interesting properties different from bulk
materials due to their extremely small size (diameter) and large specific
surface area. It is thus critical to understand the variables that control
its formation leading to a desired property. Control of nanoparticle size,  read more »

Plug Flow Reactor Setup

Plug Flow Reactor setup.jpg

It is used to determine the reaction rate constant of the reactions. In a PFR, one or more fluid reagents are pumped through a pipe or tube. The chemical reaction proceeds as the reagents travel through the PFR. In this type of reactor, the changing reaction rate creates a gradient with respect to distance traversed; at the inlet to the PFR the rate is very high, but as the concentrations of the reagents decrease and the concentration of the product(s) increases the reaction rate slows.  read more »

CSTR Setup

CSTR Setup.jpg

Capacity -2 Liters.
Description- CSTR
It is used to determine the reaction rate constant for the reaction. In an ideal CSTR, ( ideal steady state flow reactor), the contents of the reactor is well mixed and has uniform composition throughout. Thus the exit stream has the same composition as the fluid in the reactor. This type of reactor is called Mixed flow reactor. A CSTR model is used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output.
