DISPOSAL OF WASTE TYRES FOR ACTIVE CARBON PRODUCTION AND SAFE ENVIRONMENT

The aim of the present study was the investigation of new, more efficient and environmentally – attractive methods for used tyres disposal such as pyrolysis and activation for the production of active carbons. Activated carbons have been prepared from used tyres and their characteristics were investigated. Tyres were pyrolysed at 800 o C for 45 min in an inert atmosphere in the Avonmouth’s industrial pyrolyser with a throughput of 1 t/h (Compact Power Ltd, Bristol, UK). The resulting char was subsequently activated with steam in the presence of carbon dioxide at 970 o C in a batch pilot monohearth reactor at NESA facility, Louvain-la Neuve, Belgium. Activated carbons were characterised using gas (He/N2) phase adsorption at the Universite Libre de Bruxelles
