Catalytic co-pyrolysis of pine sawdust and plastics (PE, PP, and
PS) was conducted in a fluidized-bed reactor to improve the
yields of aromatics and olefins. The results show that there are
positive synergistic effects between the two feedstocks. The
maximum total carbon yield of petrochemicals (36% aromatics
+ 35% olefins) was obtained at a PE/pine sawdust ratio of 4:1
and 600 °C. LOSA-1 presents a better catalytic performance
than Al2O3 and spent FCC catalysts. Catalytic co-pyrolysis of
PS and pine sawdust produced the highest yield of aromatics
and the lowest yield of olefins because of its specially chemical
structure.
