| 1 | The effects of gas flow pattern on the generation of ozone in surface dielectric barrier discharge显示文摘Ozone production utilizing surface dielectric barrier discharge(SDBD)was experimental studied for different flow patterns considering the influences of transversal flow,lateral flow and different lateral flow positions.Results show that the flow patterns have a remarkable impact on the ozone yield by affecting the uniformity and turbulenee of gas flow.Meanwhile,distributing the O2 flow rate according to the intensity of the plasma reaction would also increase the generation efficiency of SDBD for ozone production.By improving the uniformity and introducing the lateral flow to the transversal flow,the highest ozone yield was obtained in flow pattern'F‘.In this case,the ozone yield increased by 28.4%to 131 g kWh^-1 from 102.8 g kWh^-1 in flow pattern‘A’. | 谢松汝 何勇 袁定琨 王智化 Sunel KUMAR 朱燕群 岑可法 | 2019 | Plasma Science and Technology2019，21，5： | 0 |
| 2 | Metal chloride influence on syngas component during coal pyrolysis in fixed-bed and entrained flow drop-tube furnace显示文摘Pyrolysis was carried out in an entrained flow drop-tube furnace(DTF)and tube furnace(TF)using Pingzhuang lignite coal with various catalyst concentrations(2 wt%,4 wt%,and 6 wt%)of KCl and CaCl2 for the syngas component at 800°C-1200°C.Five catalysts(KCl,CaCl2,NiCl2,MnCl2,and ZnCl2)at 6 wt%were chosen for DTF at 800°C-1200°C.An online gas chromatograph analyzer and the Fourier transform infrared spectra were used for the analysis of the syngas and char structure.Results showed that the overall CO2 and CH4 content in DTF was lower than that in TF,mainly due to the CH4 carbon reaction at high temperature.Moreover,the CO%in DTF was higher than in the TF experiment,as char reacts with carbon dioxide to form carbon monoxide.In DTF experiment,the maximum and minimum CO2 content was 15.20%with 6 wt%Mn at 800℃ and 0.33%with 6 wt%K at 1100℃,respectively.The maximum CO%was found in raw coal.Concentrations of Mn^2+,Zn^2+,and K can significantly increase H2%,whereas Ca^2+ and Ni^2+have a minor effect on H2%;however,the overall presence of catalyst has a positive impact on the H2 content. | SUNEL Kumar HE Yong WANG ZhiHua LIU LongLong ZHU YanQun CEN Kefa | 2019 | Science China(Technological Sciences)2019，62，11： | 0 |
