Welcome to the Clean Energy Research Laboratory
The multiphase flow and powder reaction engineering laboratory in the Department of Chemical and Biomolecular Engineering at The Ohio State University is engaging in teaching and research in both the fundamentals and applications of fluidization and fluid-particle principles, powder technology and multiphase reactor engineering. In the last 27 years, 30 M.S. and 40 Ph.D. degrees have been awarded from the research conducted in this laboratory and 57 Post-doctoral and visiting professors or scientists have participated or are currently participating in research here.
A wide scope of chemical engineering subjects are studied relative to fluidization engineering, or in a broader sense, particulate and multi-phase (two- and three-phase) systems. These subjects encompass fluid-solid reaction, bubbling gas-solid fluidization, liquid-solid fluidization, gas-solid pneumatic transport bed, circulating fluidized bed, high pressure/high temperature gas-solid and gas-liquid-solid fluidization, constrained gas-liquid-solid fluidization, inverse gas- liquid-solid fluidization, annular gas-liquid-solid fluidization and conventional gas-liquid-solid fluidization. High pressure/high temperature fluid and particle dynamics in multiphase flow, high pressure/high temperature sensors for flow quantification, particle image velocimetry (PIV), electrical capacitance volume tomography (ECVT), fundamental powder flow mechanics, computation, and micro-fluidics are included in our research areas.
Other studies include the devel opment of the pat ented OSCAR (Ohio State Carbonation Ash Reactivation) process for flue gas desulfurization and air toxics removal, which was commercially demonstrated at 5 MW McCracken Ohio Power plant. Also included in studies are super-reactivity limestone sorbent synthesis, and multifunctional sorbents for removal of SO2/NOx, As, Se, etc. Another recent pilot scale demonstration, the CARBONOX process, was performed at University of North Dakota's Energy and Environmental Research Center. This process removes NOX via the gas-solid reaction between NOx-laden flue gas and activated carbonaceous materials such as inexpensive high-sodium lignite coal char. Other processes under development include CO2 separation from flue gases using high reactivity metal oxides, CO2 mineral sequestration using Mg-bearing minerals, chemical looping combustion of coal, enhanced hydrogen production with in-situ CO2 capture.
