Abstract

The coal consumption will still dominate globally for electricity production and, therefore, there is a need for developing technologies with high efficiency and low emission technology for producing electricity. The technology will convert coal to syngas either directly or indirectly via ash free coal/liquid using catalyst. A low temperature catalytic gasification of low ash or ash free coals with subsequent utilization of this in fuel cell. The fuel cell produces an effluent stream of CO2 and H2O. This effluent stream can be separated easily for producing pure water and pure CO2 for utilization. There has been significant research conducted in different elements of this process scheme such as production of ash free coal or pitch from coal1 and catalytic gasification of ash free coal2 in our group. Catalytic gasification of ash free coal avoids contamination of catalyst by ash components. Heat integration will utilize heat from the fuel cell for endothermic steam gasification or production of supercritical CO2 or super critical water if needed for an energy complex. The paper will discuss other HELE options of HELE.

Dr Gupta, currently Professor in Chemical and Materials Engineering Department at the University of Alberta has conducted research in fossil fuel related areas including upgrading, combustion and gasification and emission control for more than 35 years. He completed his BTech from IIT KGP (1972) and MTech from IIT Delhi. He completed his PhD from the University of Newcastle, NSW, in 1983. He led several research projects on coal in CRC for black Coal at the University of Newcastle and led Clean Coal theme at the C5MPT at the University of Alberta. In 2017, he was awarded Percy Nichols Award jointly by ASME and SME for notable scientific and industrial achievements in the field of solid fuels. His extensive research on coal beneficiation, combustion/gasification, ash formation and Hg and carbon capture in Australia and Canada has been presented in more than 300 papers and several book chapters including more than 120 research articles in peer-reviewed international journals.
