PIROLISIS SERBUK KAYU ULIN (Eusideroxylon zwageri) DENGAN INSTRUMEN PYROLYSIS-GAS CHROMATOGRAPHY-MASS SPECTROSCOPY

Abstract

Pyrolysis of Ulin sawdust (Eusideroxylon zwageri) with pyrolysis-gas chromatography-mass spectroscopy (Py-GC/MS) instrument haw been performed. This study was conducted to determine the chemical composition resulting from the pyrolysis process of Ulin sawdust (Eusideroxylon zwageri) using the Py-GC/MS instrument. Pyrolysis was performed at a temperature of 350 ^oC, 450 ^oC and 550 ^oC under the flow of helium gas (He). The chemical composition of the product resulting from the pyrolysis process of Ulin sawdust was lignin derivative products of 56-73%, cellulose/hemicellulose derivative products of 17-22%. The pyrolysis products with the highest per cent were Phenol,4-ethenyl-2,6-dimethoxy-; .beta.-D-Glucopyranose,1,6-anhydro; and isoelemicin.
