✦ Synopsis
The formation of surface complexes on active sites during the reaction of Saran char with air at 648K has been investigated. The oxygen complexes were thermally desorbed up to 1223K as CO and CO2 following gasification of the char to different levels of burn-off. Areas occupied by the complex increased with burn-off and at burn-offs above 70% exceeded total surface area estimated from physical gas adsorption.
