Abstract

Pyrolysis gas chromatography mass spectrometry (Py-GC/MS) studies were carried out on catalyzed and uncatalyzed Nigerian corn cobs at 500oC. The catalyst used was Pd-doped γ- Al2O3.The compounds produced in the catalyzed and uncatalyzed samples were similar but in different quantities. The Pd-doped γ- Al2O3, significantly reduced the quantities of acids and alcohols from 12.84% to 4.16% and that of miscellaneous oxygenates from 2.78% to 1.45%. The quantity of phenolic compounds, aldehydes and ketones, as well as furfural increased significantly. Pd-doped γ- Al2O3 has been shown to improve the quality of bio-oil by reducing the quantities of acids and miscellaneous oxygenates in order to make bio-oil less corrosive.
