Can CO2-assisted alkane dehydrogenation lead to negative CO2 emissions?

Akash Neal Biswas received a BS in chemical engineering from the University of California, Los Angeles and is currently a chemical engineering PhD student in the Chen group at Columbia University. His research is focused on hybrid catalytic reaction schemes for carbon dioxide conversion to value-added products, in particular the coupling of thermochemical, electrochemical, and plasma chemical processes. Zhenhua Xie is currently a research associate of the Chemistry Division at Brookhaven National Laboratory. He is also serving as an investigator in the Synchrotron Catalysis Consortium (SCC). His research interests lay in the upgrading of carbon dioxide by shale gas or renewable hydrogen into value-added chemicals, employing combined approaches of precise synthesis, kinetic analysis, in situ synchrotron characterization, and theoretical calculations. Jingguang Chen is the Thayer Lindsley Professor of Chemical Engineering at Columbia University, with a joint appointment at Brookhaven National Laboratory. His research interests include fundamental understanding and techno-economic analysis of various thermocatalytic and electrocatalytic processes, including carbon dioxide conversion and shale gas utilization that are relevant to the current article.
