Correction: Co2 microwave plasma— catalytic reactor for efficient reforming of methane to syngas(Catalysts 2019, 9, 292)

Abstract

The authors found that the gas sensor analyzer had a large amount of error, and the reexperiments were tested several times. Consequently the authors wish to make the following corrections to the paper: Three sentences in line 7 from the bottom of the abstract on page 1: High CO2 and CH4 conversions of 69.3% and 81.2%, respectively, were achieved in the presence of catalyst at the same microwave power. At constant microwave power, catalyst addition increased the H2 and CO mass yield rates of 0.177 kg/h and 1.58 kg/h, respectively. Additionally, the H2 energy yield was 59.1 g/kWh. Two sentences in line 8 from the top of the conclusions on page 17: The optimized conversion ratios of CO2 and CH4 were 69.3% and 81.2%, respectively, and optimized H2 and CO mass yield rates of 0.177 kg/h (59.1 g/kWh) and 1.58 kg/h, (527 g/kWh), respectively, were measured. Importantly, the proposed hybrid system provided a low cost method with good efficiency of 62.1%. Results of concentration, flow rate, conversion ratio, mass yield rates, and energy efficiency were corrected on Pages 10–13: The concentration of CO2 was reduced from 23.4% to 9.8%, and that of CH4 was reduced from 20% to 6%. The concentration of H2 increased from 27.7% to 35.2%, while that of CO increased from 24.9% to 44.9%. The flow rates of CO2 and CH4 from 10.06 to 4.61 L min–1 and from 8.6 to 2.82 L min–1. The H2 and CO flow rates from 11.91 to 16.54 L min–1 and from 10.71 to 21.1 L min–1. The conversion of CO2 increased from 32.9% to 69.3%, while that of CH4 increased from 42.7% to 81.2%. The H2 and CO mass yield rates in the hybrid system increased to 0.177 kg h–1 and 1.58 kg h–1. The efficiency of dry reforming increased from 36.8% to 62.1%.(Table presented).
