Pyrolysis-GC/MS study of fast growing wood Macaranga gigantea

Abstract

Py-GC/MS study on fast growing wood Macaranga gigantea at different temperatures has been conducted. The pyrolysis yields and chemical compounds obtained based on the pyrograms of the biomass by Py-GC analyses were compared with those obtained from batch pyrolysis experiments under similar conditions. Results show that the pyrolysis yields of Macaranga gigantea from Py-GC/MS analyses and batch reactor experiments at 300-450 oC were generally similar, ranging from 35 to 65%. Pyrolysis of the woody biomass with both techniques produced compounds which are mostly derived from pyrolysis, thermal degradation, or volatilization of lignin and cellulose/hemicellulose.
