Porous Carbons Obtained from Lignite, Anthracite and Graphite in a Bed of Slag and Catalyst Particles

Abstract

This paper describes the influence of solid fuel nature and conditions of thermal treatment in a flow reactor with a fluidized and fixed bed of slag and catalyst particles on the porosity of obtained carbon products. Lignite, anthracite and natural graphite were used as starting raw materials. Optimal conditions of thermal treatment providing the formation of porous carbons were selected for the each type of a raw material: pyrolysis with high rate of heating (flash pyrolysis) for lignite, the same combined with steam activation for anthracite and chemical modification and flash pyrolysis for natural graphite.
