报告摘要:
Capture and conversion of CO2 from industrial flue gases are important for reduction of carbon emissions and for sustainable energy solutions, so are the capture and conversion of SO2 from various industrial flue gases or tail gases. This presentation will highlight the new design approach to CO2 capture using molecular basket sorbents, and the synergy of non-thermal plasma with dielectric barrier discharge and heterogeneous catalysis in CO2 hydrogenation to hydrocarbons, as well as SO2 reduction to elemental sulfur using supported metal-based catalysts related to CCU. For removal of SO2 from flue gas, flue gas desulfurization (FGD) is used worldwide in scrubbers to convert SO2 with Ca-based sorbent to form CaSO3 which is then disposed as solid waste. We present a new design approach based on non-thermal plasma-enhanced catalysis for direct one-step SO2 reduction to elemental sulfur (SO2 to S) over transition metal sulfide catalysts. We have developed SO2-selective solid molecular basket sorbent that is regenerable for adsorptive separation of SO2 from gas mixture. For low-temperature SO2 reduction to elemental sulfur in a flow reactor, coupling non-thermal plasma with supported transition metal catalysts can significantly promote low-temperature reduction of SO2 by up to 200%, with over 98% selectivity to elemental sulfur. Strong synergistic effects are attained, as the sulfur yield is about 47–82% higher than the sum of the yield when using plasma alone or catalyst alone. Recent advance in synergy of non-thermal plasma and supported metal catalysts for CO2 hydrogenation to hydrocarbon chemicals and fuels at low temperatures will also be briefly discussed.
