Flame-retardant plastics, such as desktop and laptop personal computer bodies, could be completely liquefied by carbon materials-catalyzed
hydroliquefaction in tetralin without using H2 as a hydrogen source. Active carbons with larger surface areas (1450–3450 m2/g) acted as superior catalysts in transferring tetralin hydrogens to plastics. On the other hand, carbon blacks and fullerene-rich
soot were less active catalysts. Graphite and mesocarbon microbeads did not show any catalytic effects. Benzene, toluene,
and ethylbenzene were obtained as recyclable hydrocarbons; their total amounts varied from 4 wt% to 12 wt% depending on the
types of plastics and the carbon materials used. Organic bromides such as polybromodioxins were not contained in the gases
and oils of the product.
