Pen-Chi Chiang is a Distinguished Professor of Graduate Institute of Environmental Engineering, National Taiwan University, and a Director of Carbon Cycle Research Center of National Taiwan University. He obtained Ph.D. degree from the Department of Civil Engineering, Purdue University, USA in 1982. Among his current interests is CO2 capture and utilization by mineralization using various alkaline wastes. He worked on developing innovative process for mineralization such as slurry reactor, autoclave, and rotating packed bed. Along the way, the critical issues on CO2 mineralization research, such as process chemistry, reaction kinetics, mass transfer, energy consumption and cost-effective analyses, have been comprehensively studied. Meanwhile, the developed CO2 mineralization process has been applied into steelmaking and petrochemical industries in Taiwan. On the other hand, he worked on establishment of policies and strategies for deploying CO2-related technologies in Taiwan. Dr. Chiang has published > 200 paper papers in the above area since 1990.
