TÓM TẮT
Radio frequency (RF) inductively-coupled plasma has offered novel routes to chemical processes. In this work, the conversion of CO2 with other co-reactants i.e., CH4 and H2O (steam) was performed under inductively-coupled plasma-alone and plasma combined with the Cu/Al2O3 catalyst. In this work, the Cu/Al2O3 was prepared by the impregnation method and characterized by field-emission scanning electron microscopy (FESEM) and powder X-ray diffraction (XRD). Experimental results displayed that the dissociation of CO2 and high syngas (H2, CO) selectivity could be achieved under mild conditions (low input power of 50 W). The combination of plasma and the Cu/Al2O3 catalyst enhanced CO2 conversion and product selectivity significantly. At the input power of 50 W, about 21 % CO2 was converted to a syngas ratio of 1.2 over the process plasma-alone while almost 31 % CO2 was transformed to a syngas ratio of 2.1 with the presence of the catalyst. The Cu/Al2O3 catalyst offered active surface to promote the re-combination of active species such as H* and CO* to yield syngas, and thereby, increasing targeted product selectivity.
