“…Mathematical models of gasification processes under the influence of solar radiation are proposed in [53][54][55][56][57][58]. Allothermal processes of biomass pyrolysis and gasification were investigated in [59][60][61][62][63][64][65][66][67], including those in a staged gasification unit [68,69]. Schemes with the heat recirculation of the produced gas were proposed in [70].…”

Plant biomass is one of the most widespread renewable energy sources. Energy utilization of biomass allows solving some problems associated with the development of off-grid energy systems and the processing of combustible waste (primarily agricultural and forestry waste). This paper is devoted to the study of an allothermal gasification process of plant biomass materials using a kinetic-thermodynamic model developed by the author. The gasification process is considered stationary, and steam is used as a gasification agent. The power of the supplied heat is considered constant (10 kW). One of the significant tasks related to allothermal gasification is to choose flowrate parameters so that the heat supplied is efficiently used in chemical reactions without the threat of reactor overheating. The determination of the boundaries of the safe gasifier operation involved variant calculations with a view to optimizing the gasification conditions. The calculation results show that the allothermal gasification process can proceed with a thermochemical efficiency of about 70%. For each fixed fuel consumption level, there is an optimal fuel-steam ratio. The complete conversion of biomass requires sufficiently high temperatures. The produced gas contains a significant steam fraction (>50 vol%) even under optimal conditions. The calculated fraction of hydrogen in dry gas is up to 60vol%. The data obtained can be used to assess the efficiency of energy units with biomass gasification using high-temperature sources, for example, in systems that use and store solar thermal energy.

“…In the last few decades, the problems of carbon-containing materials reforming into synthesis gaseous fuel-mixture CO and H 2 -by means of plasma technologies were widely discussed in the scientific literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. This syngas can be used for heat or electrical energy production [13].…”

The chapter is devoted to the development of technologies for the processing of carbonaceous wastes, including hazardous ones, using plasma energy sources. In particular, plasma-steam equipment provides complete environmental safety and high quality of the synthesis gas produced. Its application is also discussed to exclude the risk of environmental pollution by heavy metals, if they are contained in the recycled waste. The advantages of using oxygen instead of air as an additional reagent in gasification processes are underlined. It is shown that the proposed variant of the processing technology corresponds well to the general idea of numerous publications in the world scientific literature, known as the Waste-to-Energy. It has been shown that plasma equipment has significant advantages in terms of the commercialization of processes for the treatment of sewage sludge and some other hazardous waste.
