CO2 reforming of CH4 by the combination of dielectric barrier discharge plasma and zeolite catalysts

摘要

Dry reforming of methane that converts two greenhouse gases (CH4 and CO2) to syngas (mixture of CO and H2) has gained a great research interests. Several technologies were proposed for CO2 reforming of CH4, such as catalytic conversion, plasma conversion and combination of catalyst and plasmas [1]. Recently, the combination of plasmas and heterogeneous catalysis for fuel production from CH4 reforming has attracted the increasing interest [2-3]. In this research, we investigated the CO2 reforming of CH4 to syngas by the combination of dielectric barrier discharge (DBD) plasmas and zeolite catalyst particles. The experimental results showed that the conversion efficiencies of CO2 and CH4 using the combination of plasma and zeolite catalysts are higher than those by using plasma only.
