Catalytic fast pyrolysis of sewage sludge was conducted considering the effects temperature, atmospheres and catalysts on carbon nitrogen distributions using a fixed-bed reactor. H2 atmosphere gave lowest selectivity solid products highest gaseous yield over HZSM-5 (HZ) at same temperature compared to Ar steam. Higher led an increase in decrease solids. increased light aromatics (LAs), whereas steam reduced generation LAs. Over 0.5Ni-HZ, LAs 11.4%, 1.6% obtained from noncatalytic SS. atmospheres, metal-loaded HZ promoted transfer into products. The NH3 55.6% 700 °C under atmosphere.
