Waste Gasification by Thermal Plasma: A Review

“…The cracking of tars by cold plasma in series with gasification reactor has been studied and several groups have demonstrated with success that organic elements (tars and particles) can be easily decomposed by corona discharges or by gliding-arc [48,[60][61][62][63]. The role of the plasma treatment is twofold: it allows, on the one hand, a significant purification of gas by limiting the production of tars and on the other hand, producing a synthesis gas enriched in hydrogen (water-gas shift reaction).…”

Water Plasmas for Environmental Application

“…Kim et al [25] used nitrogen or argon to protect tungsten cathode. Glocker et al [16] used hydrogen to protect tungsten cathode. These protection gases are not favorable for industrial applications owing to economical reason.…”

“…Waste decomposition using thermal plasmas has been reported for various kinds of wastes, such as halogenated hydrocarbon [10][11][12][13][14][15][16][17][18][19][20][21][22][23], polychlorinated biphenyl (PCB) [24,25], hydrocarbon [26][27][28], polymer [29][30][31], organic waste [28,[32][33][34][35][36][37], used tires [38][39][40], and medical waste [41,42]. Waste materials can be efficiently degraded by thermal plasmas under reducing or oxidizing conditions.…”

Treatment of Hydrogen Fluoride Generated from the F-gases Decomposition Processes

“…However, with the above-mentioned technologies, there are many problems such as a low decomposition efficiency, high operating cost, and the formation of by-products: NO x , SO x , HF, CO 2 , etc (Mi et al, 2015;Park et al, 2013;Wang et al, 2004;Bonarowska et al, 2001;Wang et al, 1998). Afterward, the plasma process and electronbeam system have been exploited for improving previous technologies (Son et al, 2016;Ryu et al, 2012;Watanabe et al, 2008;Kossyi et al, 2001;Glocker et al, 2000;Murphy et al, 1998). Meanwhile, Park et al (2013) reported that the plasma process obtained a high decomposition efficiency of PFCs when using hydrogen gas as an addictive.…”
