Methane activation under dielectric barrier discharge plasma interacting with mesoporous material
نویسندگان
چکیده
Direct methane activation on a mesoporous material under dielectric barrier discharge (DBD) plasma was investigated in the present study. The specific surface area of the mesoporous material (SBA-15) was controlled by varying the hydrothermal reaction temperature to investigate the effect of the specific surface area on the methane activation. As a result, methane conversion increased as the specific surface area increased and the discharge frequency decreased. Energy efficiency was higher when the specific surface area of 516 m·g was interacted with the plasma generated at the frequency of 0.1 kHz.

Synergetic Effects of Plasma, Temperature and Diluant on Nonoxidative Conversion of Methane to C2+ Hydrocarbons in a Dielectric Barrier Discharge Reactor
Noncatalytic and nonoxidative conversion of methane in a dielectric barrier discharge (DBD) reactor is examined at different temperatures, gas residence times and input powers. In addition, the ratio of methane to helium as a diluant, is changed in the range of 0.6 to 1.8. Results show significant synergetic effects of plasma, temperature and helium on the methane conversion and C2+</s...

متن کاملCO2 reforming of methane: valorizing CO2 by means of Dielectric Barrier Discharge
The impact of pollution on the environment is causing several problems that are to be reduced as much as possible. One important example is the production of CO2 that is emitted by many transport and industrial applications. An interesting solution is to view CO2 as a source instead of a product that can be stocked. The case considered in this work is the CO2 reformation of methane producing hy...

متن کاملA Numerical Study of the Sour Gas Reforming in a Dielectric Barrier Discharge Reactor
In this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. CH4, CO2, and H2S, to the various charged particles and syngas in a dielectric barrier discharge (DBD) reactor is studied. An electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. Based on the space...
