“…The highest guaiacol content (7.8 lg/mg lignin) was observed at 900°C and 0.5 MPa (50 psig). In literature, most of pressurized pyrolysis and gasification were conducted at pressure below 150 psig [7,27,28]. At reaction pressure below 150 psig, our observations on the effect of temperature on tar contents were consistent with literature.…”

“…The effects of pressure on the polyaromatic hydrocarbon were explained by Mayerhofer et al [27]. On one hand, increase in system pressure caused the reaction equilibrium to shift to fewer molecules based on equilibrium law.…”

“…At reaction pressure below 150 psig, our observations on the effect of temperature on tar contents were consistent with literature. Mayerhofer et al [27] reported that tar composition varied with temperature. Phenolic species (phenol and cresols) greatly decreased with increasing temperature whereas naphthalene increased with increasing temperature.…”

“…About the residence time, Kinoshita et al [52] concluded that it has a little influence on the tar level, but it has significant influences on the tar composition. About the oxidizing agent/waste ratio, it is observed the decrease in tar yield by increasing this ratio [49]. Gasification can operate under atmospheric to high pressures.…”

“…The main solutions proposed in the scientific literature are to optimize the design of the gasification reactor, its operating parameters (temperature, pressure, oxidizing agent/waste ratio, residence time …), by adding catalyst or by plasma treatment [46][47][48][49][50][51][52][53][54][55][56][57]: The gasification temperature (> 1 200 K -1 300 K) has a beneficial effect to minimize the tar quantities and allows destroying the aromatics without a catalyst [47,51]. A reduction of more than 40 % in tar yield has been reported when the temperature was raised from ~ 1 000 K to ~ 1 200 K.…”

waste gasification processes based on thermal plasma (DC or AC plasma torches) at lab scale versus typical performances of waste autothermal gasification: LHV of the syngas, cold gas efficiency and net electrical efficiency. In the last part, a review has been done on the various torch technologies used for waste gasification by plasma at industrial scale, the major companies on this market and the perspectives of the industrial development of the waste gasification by thermal plasma. The main conclusions are that plasma technology is considered as a highly attractive route for the processing of waste-to-energy and can be easily adapted to the treatment of various wastes (municipal solid wastes, heavy oil, used car tires, medical wastes …). The high enthalpy, the residence time and high temperature in plasma can advantageously improve the conditions for gasification, which are inaccessible in other thermal processes and can allow reaching, due to low tar content in the syngas, better net electrical efficiency than autothermal processes.

The Physico‐chemical characteristics are inherent properties of fuel and their behaviour changes in different gasification conditions. The critical properties of the coal impede the gasifier's performance, and hence, a proper study is needed to develop and further enhance the gasification systems. A proper assessment of factors influencing gasifier performance and their optimization enables to select, alter, and adjust the conditions. The present paper reviews the effect of important coal properties and gasifier operating conditions on gasification performance parameters. Further, the suitability of gasifiers (moving bed, fluidized bed, and entrained flow) according to the physico‐chemical properties of fuel along with proper operating parameters has also been studied.
