The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

SINOPSIS

A combined thermolysis-plasma facility has been designed at the A.V. Luikov Heat and Mass Transfer Institute to treat wastes with a predominant organic part. The aim of this work was to carry out numerical modeling of the processes occurring in a plasma reactor to find optimum parameters of the treatment process for different regimes. A warm-up mode and model mixture (23.4CO2 + 2C6N6 + 3C4H6) conversion mode of the reactor were considered to determine the effect of a number of parameters (radiation influence, soot formation, interaction of soot with radiation, heat losses). Experimental studies of plasma gasification of wastes were carried out. Tire scrap was considered as a model material. It was previously decomposed in a thermolysis reactor into an evaporated volatile hydrocarbon fraction and a solid carbon residue. Only the evaporated fraction was subjected to plasma gasification. Comparison of calculated and experimental data showed that the model correctly describes the qualitative distribution of the temperature field over the volume of the reactor. The influence of radiation heat transfer on the temperature distribution and the effect of heat loss through the side walls of the reactor on the temperature distribution and gas concentrations were shown. It was found that soot formation and its interaction with radiation must be taken into account because of the changes in the distribution of temperature and CO2 concentration. Modeling of the reactor input unit was performed to improve the processes of mixing. The model qualitatively predicts the behavior of the reactor depending on the regime, but it should be improved for quantitative prediction.
