Preparation of syngas from the semi-coke of Borodino coal for solid oxide fuel cells

Abstract

Syngas for the battery of solid oxide fuel cells is produced in a gas generator with a fluidized layer consisting of a mixture of electrocorundum and semi-coke of the Borodino coal at the temperature of 850 °C, fluidizable by steam in a retort heated from the outside. The concentration of semi-coke is 627 kg per 1m3 of mixture of electrocorundum and semi-coke. The heat of combustion of the obtained syngas is 13359 kJ/kg. Syngas is purified in a cyclone-dust collector and gas purification from SO2 and H2O. © The Authors, published by EDP Sciences, 2018.
