THERMAL PROCESSING OF WASTE PLASTICS

RAW MATERIAL

PROCESS

PRODUCT

Product is a full value solid fuel.

THERMOLYSIS

Karboterm

Two stage process

WP/bitum ratio : 4 / 1

Temp. : 350oC

Time: 60 min

Ash : 10 %

Heating value : 30000 kJ/kg

Sulfur : < 0,8 %

Chlorine : < 0,2 %

Composition

Description:

Prepared waste plastics are thermally processed with an addition of carbo- or petrochemical bitumens. The reduction of volatile hydrocarbons and elimination of chlorine from polymer decay are characteristic for the process.

Hot liquid semi-product is cooled by mixing with a grained hard coal.

Product application:

Karboterm is a full value component for a coal blend in coking plants or a fuel in power plants with a grained hard coal.
