Thermal-catalytic gas processing is integral to many current industrial processes. Ever-increasing demands on conversion and energy efficiencies are a strong driving force for the development of alternative approaches. Similarly, synthesis of several functional materials (such as nanowires and nanotubes) demands special processing conditions. Plasma catalysis provides such an alternative, where the catalytic process is complemented by the use of plasmas that activate the source gas. This combination is often observed to result in a synergy between plasma and catalyst. This Review introduces the current state-of-the-art in plasma catalysis, including numerous examples where plasma catalysis has demonstrated its benefits or shows future potential, including CO2 conversion, hydrocarbon reforming, synthesis of nanomaterials, ammonia production, and abatement of toxic waste gases. The underlying mechanisms governing these applications, as resulting from the interaction between the plasma and the catalyst, rend...

Plasma Catalysis: Synergistic Effects at the Nanoscale

Plasma catalysis holds great promise for environmental applications, provided that the process viability can be maximized in terms of energy efficiency and product selectivity. This requires a fundamental understanding of the various processes taking place and especially the mutual interactions between plasma and catalyst. In this review, we therefore first examine the various effects of the plasma on the catalyst and of the catalyst on the plasma that have been described in the literature. Most of these studies are purely experimental. The urgently needed fundamental understanding of the mechanisms underpinning plasma catalysis, however, may also be obtained through modelling and simulation. Therefore, we also provide here an overview of the modelling efforts that have been developed already, on both the atomistic and the macroscale, and we identify the data that can be obtained with these models to illustrate how modelling and simulation may contribute to this field. Last but not least, we also identify future modelling opportunities to obtain a more complete understanding of the various underlying plasma catalytic effects, which is needed to provide a comprehensive picture of plasma catalysis.

Destruction of hydrogen sulfide by a wire-tube dielectric barrier discharge (DBD) AC plasma reactor was carried out at atmospheric pressure and room temperature. Six aspects, effect of applied voltage, initial H2S concentration, gas flow rate, pellets in the reactor, DBD reactor materials, and DBD dielectric thickness on H2S removal efficiency were investigated. Furthermore, specific energy density (SED), absolute removal amount (ARA), and energy yield (EY) during the discharge process were investigated at the same time. In addition, ozone generation during the decomposition of H2S was also studied. Experimental results demonstrated the application of DBD AC plasma was an effective technology for odor elimination.

Control of Hydrogen Sulfide by a Wire‐Tube Dielectric Barrier Discharge AC Plasma Reactor

An environment-friendly dust covering agent and a preparation method thereof belong to the field of dust-suppressing materials. The components of the environment-friendly dust covering agent include water, corn straw, industrial starch, alkaline substance and polyvinyl alcohol according to the weight ratio of 100:2 to 6:2 to 8:0.1 to 0.3:0.1 to 0.5. The preparation method includes the following steps: the ground corn straw is added into the water; after the water is heated until the temperature is increased to 30 DEG C to 35 DEG C, the industrial starch is added, and solution containing the starch and the straw is produced under heating and stirring conditions; after the temperature is increased to 50 DEG C to 60 DEG C, the alkaline substance is added, and stirring is constantly carried out; after the temperature is increased to 65 DEG C to 90 DEG C, the polyvinyl alcohol is added, stirring is carried out for 10 minutes and then stopped, and after natural cooling, the covering agent is prepared. The PH value of the covering agent is between 8 and 9; the viscosity number of the covering agent is between 160mPa.s and 442mPa.s, so the covering agent has higher stickiness; and the storage time of the covering agent is increased to 15 days, so the preservability of the product is effectively enhanced.
