Plasma-Thermal Gasification of Organic Wastes

Abstract

This paper presents the results of computational and experimental studies of the electroplasma gasification of carbon-containing technogenic wastes to obtain high-calorific-value syngas (H 2 + CO) for power-generating devices. The composition of the syngas produced by gasification of organic wastes was experimentally determined. The change in the composition and calorific value of the syngas depending on the gasification time of organic materials was studied. The change in the calorific value of the syngas during waste gasification is considered.

Electrification of gasification-based biomass-to-X processes – a critical review and in-depth assessment

“…An'shakov et al conducted experiments on organic wastes using a two-stage process with plasma usage in both reactors. 209 A first plasma torch is used in the gasifier, while an electric-arc plasma torch in the second reactor maintains the temperature at 1300-1500 1C. 209,210 Vishwajeet et al conducted experiments using a two-stage gasification system coupling a prototype-entrained flow plasma-assisted gasification reactor with ex-situ plasma vitrification.…”
