通过形成滑动放电（称为 GlidArc）产生等离子体的新方法已经开发出来。至少两个发散电极被放置在快速气流中并且沿流动方向。放电在电极之间和流中组织。电极上放电根的位移可防止其腐蚀。电能直接且完全地传递给气体。所有气体或蒸汽，包括灰尘和/或雾气，都可以在任何入口温度和 0.1 - 5 atm 压力下直接处理。相对低密度下的大等离子体体积不符合热力学平衡。 GlidArc 的一些应用在实验室和工业规模反应器火焰过热（电燃烧器）、挥发性危险化合物空气净化、浓 H2S 或 H2S + C2 烟气 SO2 还原为元素硫、天然气转化为合成气 (H-2 + CO) 的完全或部分增值、天然气转化为合成气 (H-2 + CO) 中进行了测试。廉价的滑行放电可以大大减少传统气体工艺的滋扰。这种放电给这些过程带来了易于控制的能量，使得高温下的高能耗热过程可以被这种冷催化等离子体过程所取代，并且能量消耗较低。
New way of plasma generation by formation of gliding electrical discharges (called GlidArc) has been developed. At least two diverging electrodes other are placed in a fast gas flow and in the flow direction. The discharges are organized between the electrodes and across the flow. The displacement of the discharge roots on electrodes prevents their erosion. The electrical energy is directly and totally transferred to the gas. All gas or vapor, also dusty and/or misty, can be directly processed at any inlet temperature and 0.1 - 5 atm pressures. Big plasma volume at relatively low density is out of the thermodynamic equilibrium. Some applications of the GlidArc were tested in laboratory and industrial scale reactors flame overheatng (electro-burner), air depollution from volatile hazardous compounds, complete or partial valorization of concentrated H2S or H2S + C2 flue gas SO2 reduction to elementary sulfur, natural gas conversion to the syngas (H-2 + CO).Inexpensive gliding electric discharges can considerably reduce the nuisances of classical gas processes. Such discharges bring to these processes an easily controllable energy so that high energy consuming thermal processes at high temperatures can be substituted by this cold and catalytic plasma process at lower energy expense.
