Effect of the ozonization of brown coal from the Kansk-Achinsk Basin on its pyrolysis in a mixture with polyethylene

It was found that the treatment of brown coal from the Kansk-Achinsk Basin with an ozone-oxygen mixture at 25–100°C for 1–8 h was accompanied by the formation of oxygen-containing structural groups in the organic matter of coal; the thermal stability of these groups was comparatively low. The prelim...

Description
Summary:It was found that the treatment of brown coal from the Kansk-Achinsk Basin with an ozone-oxygen mixture at 25–100°C for 1–8 h was accompanied by the formation of oxygen-containing structural groups in the organic matter of coal; the thermal stability of these groups was comparatively low. The preliminary ozonization of coal resulted in an increase in the degree of conversion and the yield of liquid distillation products in the course of coprocessing of coal with polyethylene.
