This work addresses enhanced benzene,toluene and xylene(BTX)production by catalytic fast co-pyrolysis from agroindustrial biomass blended with PVC and the use of prepared NaZSM-5 and HZSM-5.Results from catalytic fast pyrolysis of biomass indicates that oxygen-containing compounds decreased whereas aro-matics increased.The catalytic effect of mineral content altered the co-pyrolysis intermediates by increasing the formation of mono-aromatics while reducing poly-aromatic hydrocarbons.Furthermore,the addition of PVC strongly influenced thermal decomposition of agricultural waste biomass,where BTX yields were enhanced up to 26.6% and 25.1% for 1:2 OP/PVC-HZ and 1:2 AS/PVC-HZ,respectively.Yields of toluene and xylene peaked at 19% and 1_(0.5)% hydrocarbon yields with 1:2 OP/PVC-HZ blend.Additionally,from the pyrolytic gas,CH4 yields increased while the CO2 yield fell due to oxygen removal by decarboxylation.These findings could provide a great insight into the olive pomace and almond shell valorization through an inexpensive and straightforward easy process.
