<span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#201F1E">The concept of excess enthalpy combustion was proposed several decades ago, wherein combustion is carried out in a reactor -- heat-exchanger arrangement. The enthalpy of combustion
is then recirculated into the device by preheating the incoming feed using the hot exhaust gases. Around the same time, the concept of running mildly exothermic reactions in a heat-exchanger-like arrangement was commercialized in the petrochemical industry,
exemplified by the ICI and Casale reactors for ammonia and methanol synthesis. <o:p></o:p></span></p>

<span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#201F1E">This talk will focus on using this internal heat recirculation concept for "process intensification" in microreactors for energy applications. First example will discuss combustion
in a heat recirculating microreactor, and coupling it with thermo-electric module for power generation. The second example will be that of exploiting this idea for improving methane yields in an autothermally operated microreactor for catalytic CO<sub>2</sub>
methanation. The common concepts across combustion and mildly exothermic CO<sub>2</sub> reduction will be explored. This example will be used to show the relevance of basic engineering principles that are introduced in core UG courses. Finally, this talk will
segue into efforts at NPTEL/Swayam -- a national MOOCs program in India -- towards making education relevant and accessible.<o:p></o:p></span></p>

for Technology Enhanced Learning), a national MOOCs program in India, as well as online degree program of IIT Madras. Niket completed his PhD in Chemical Engineering at Georgia Tech in December 2004. After his postdoctoral research at the University of Delaware,
Niket joined as an assistant professor in IIT Madras in summer 2007. Between 2011 and 2014, Niket spent three years in industrial R&D, first at General Motors and then at ABB Corporate Research in India. He rejoined as a faculty at IIT Madras in November 2014.
His research interests are broadly in the area of using experiments and multiscale modeling in combustion, catalysis and control for energy applications.<o:p></o:p></span></p>
