“…This is well seen in Fig. 3 showing also kinetics of CH 4 and products of its conversion when initial gas temperature is 1,800 K. The temperature drops in 1 s to 1,340 K due to transpiring reactions. The temperature drop means that overall process is endothermic.…”

“…Significant changes in concentrations of CH 4 and main products start from 20 ls. During 1 s methane decreases and hydrogen increases almost linearly, whereas acetylene reaches plateau at 0.1 s. Ethylene and ethane are characterized by the first peak at 0.2 ms followed by a slow decrease to the minimum at 22 ms and then their concentrations increase again.…”

“…methane [1,2]. The microwave plasma source (MPS) developed in our lab [3][4][5][6] is an efficient apparatus for hydrogen production via hydrocarbons conversion. Although the presented MPS draws a parallel to other known atmospheric pressure microwave discharges such as a microwave torch [7] or a surfaguide-produced surface-wave discharge [8], which is also a waveguide-based ones, it also draws some significant distinctions.…”

Results of chemical kinetics modeling in methane subjected to the microwave plasma at atmospheric pressure are presented in this paper. The reaction mechanism is based on the methane oxidation model without reactions involving nitrogen and oxygen. For the numerical calculations 0D and 1D models were created. 0D model uses Calorimetric Bomb Reactor whereas 1D model is constructed either as Plug Flow Reactor or as a chain of Plug Flow Reactor and Calorimetric Bomb Reactor. Both models explain experimental results and show the most important reactions responsible for the methane conversion and production of H 2 , C 2 H 2 , C 2 H 4 and C 2 H 6 detected in the experiment. Main conclusion is that the chemical reactions in our experiment proceed by a thermal process and the products can be defined by considering thermodynamic equilibrium. Temperature characterizing the methane pyrolysis is 1,500-2,000 K, but plasma temperature is in the range of 4,000-5,700 K, which means that methane pyrolysis process is occurring outside the plasma region in the swirl gas flowing around the plasma.

Plasma‐electrified up‐carbonization for low‐carbon clean energy

et al. 2022

View full text Add to dashboard Cite

Low-value, renewable, carbon-rich resources, with different biomass feedstocks and their derivatives as typical examples, represent virtually inexhaustive carbon sources and carbon-related energy on Earth. Upon conversion to higher-value forms (referred to as "up-carbonization" here), these abundant feedstocks provide viable opportunities for energy-rich fuels and sustainable platform chemicals production. However, many of the current methods for such up-carbonization still lack sufficient energy, cost, and material efficiency, which affect their economics and carbon-emissions footprint. With external electricity precisely delivered, discharge plasmas enable many stubborn reactions to occur under mild conditions, by creating locally intensified and highly reactive environments. This technology emerges as a novel, versatile technology platform for integrated or stand-alone conversion of carbon-rich resources. The plasma-based processes are compatible for integration with increasingly abundant and cost-effective renewable electricity, making the whole conversion carbon-neutral and further paving the plasma-electrified upcarbonization to be performance-, environment-, and economics-viable.Despite the chief interest in this emerging area, no review article brings together the state-of-the-art results from diverse disciplines and underlies basic mechanisms and chemistry underpinned. As such, this review aims to fill this gap and provide basic guidelines for future research and transformation, by providing an overview of the application of plasma techniques for carbon-rich resource conversion, with particular focus on the perspective of discharge plasmas, the fundamentals of why plasmas are particularly suited for upcarbonization, and featured examples of plasma-enabled resource valorization. With parallels drawn and specificity highlighted, we also discuss the technique shortcomings, current challenges, and research needs for future work.

A simultaneous investigation of simulation and experimental analysis of hydrogen production from argon‐water vapor mixture as a function in DBD plasma applied voltage were studied. The H2 concentration results of two Ar‐H2O simulation kinetics models were compared with the experimental results. The simulation analysis was implemented for Ar‐H2O models with and without the dissociative attachment reaction (H−). The effects of argon flow rate, input water vapor temperature, and water vapor flow rate on the H2 concentration from the Ar‐H2O mixture were investigated. Furthermore, the effect of argon addition and reactor temperature on the hydrogen production from water vapor plasmolysis was performed. It was found that the hydrogen concentration was enhanced with the argon gas flow rate and plasma voltage increase. Moreover, the H2 concentration results of the water vapor simulation model selecting the dissociative attachment reaction (H−) were nearly the same as that obtained from the experimental results. Also, it was observed that the energy efficiency was enhanced with the plasma input power increased. Moreover, the comparison showed that the hydrogen concentration of argon gas addition was lower than that obtained from water vapor plasmolysis at PTR heating temperature of 90°C.
