Projects

Designed, Commissioned, and Operated the 20 kW Pressurized Entrained Flow Reactor

Designed to operate upto 1650°C and 435psi, with coal/petcoke feed rates of 0.06-1.8 kg/hr and gas mixtures of CO2, O2, N2, air and steam.

Particle heating rate as high as 170,000 °C/s can be reached at 1500°C.

Applications of the reactor:

Organic and inorganic transformations of solid fuels during oxy-fuel combustion and gasification at elevated pressures
Catalytic studies

Other collaborators: Aime Tchapda and Nandakumar Krishnamurthy

Micro reactor used for coal liquefaction process

Direct Coal Liquefaction Process

Coal Liquefaction experiments were conducted at 450°C and 950 psi in tetralin with phenol as an additive to increase liquefaction yield

Rheometer

A model was developed to predict viscosities of coal-derived liquids, defined compounds and light crude oils

Other Projects:

1. Proposed a novel method to dispose electronic waste

2. Developed a novel bio-inhibitor to reduce corrosion of mild steel in acidic environment

3. Removed toxic Nickel from aqueous solution using activated carbon, developed from

Abelmoschus Manihot, as adsorbent

4. Implemented partial switching of pneumatic conveying to mechanical conveying for cement transport

(Industrial Project)

5. Installed an arrangement to feed biomass and other waste materials to calciner in a cement

plant.
