The evolution of the pyrolysis products of olive kernel, a municipal solid waste fraction and a sewage sludge was analyzed qualitatively and quantitatively, using a properly developed and calibrated system of coupled thermogravimetry-mass spectrometry (TG/MS). The TG/MS profiles of the volatile products were also related to the pyrolysis thermograms, after their deconvolution which was performed using an independent parallel reaction kinetic model. The results from the co-pyrolysis of two mixtures of olive kernel with the municipal waste fraction and with sewage sludge at 7:3 mixing ratio revealed strong synergy effects on the production of CO up to 600 °C and the production of H2 at elevated temperatures. Other compounds were found to present slight synergistic (hydrocarbons up to C3, HCl, HCN) or additive behavior (CO2, H2O, NH3). No significant effect of co-pyrolysis on the anticipated quantities of char, tar and on the heating value of the pyrolysis gases of the mixtures was observed.
