Fast pyrolysis of agroindustrial wastes blends: Hydrocarbon production enhancement

Fast pyrolysis of waste from agroindustry may be an alternative choice for sustainable use enhanced biofuels. Plastics are one option improving the hydrogen to carbon efficiency ratio (H/Ceff) biomass feedstock. Waste in blends with could modify reaction mechanism removing oxygen by substituting decarbonylation and decarboxylation dehydration. Firstly, fast was performed find optimal mass blending olive pomace (OP) agroindustrial polymers (polyethylene (PE), polystyrenes (PS) polyvinyl chloride (PVC)) according hydrocarbon production. Experimental results 1.5:1 OP/PE, 1:1.5 OP/PS OP/PVC ratios at 500 °C, showed synergistic enhancement yields. Alkenes yield were where light hydrocarbons fraction (C6-C10) first increased then decreased temperature, reaching a maximum 650 °C. For OP/PVC, it improved aromatic compounds formation, being °C temperature former later, respectively. Benzene, toluene xylene large quantities obtained PS PVC OP. Additionally, effect on did not show any clear trend pyrolytic gas emissions. In general, as increased, CO CO2 emissions fell CH4 enhanced. Finally, olefin yields promoted higher H/Ceff.
