Abstract
Co-pyrolysis of bisphenol A polycarbonate with lignoboost
(regular and modified) lignin from softwood and with
organosolv lignin from hardwood was performed in a
semi-batch reactor at 500 °C and self-generated pressure.
Catalytic upgrading was performed at 300 °C over MCM-41
and SBA-15 catalysts. The effect consisted in conversion
of bisphenol A into phenol and its light derivatives.
Hydrogenation occurred during upgrading based on the
hydrocarbons converted into coke on the surface of
catalysts. The Al-MCM41 with Si/Al ratio of 16 (MCM16)
and Al-SBA-15 with Si/Al ratio of 48 (SBA 48) catalysts
had similar effects for the lignoboost lignins, with
slight advantage for the MCM16 in the case of regular
lignoboost while MCM16 was clearly the best one for the
organosolv lignin in converting the heavier compounds
into lighter ones
