ResumoGas and liquid products evolved in the process of carbon adsorbent production by steam pyrolysis of apricot stones and coconut shells are investigated. The oils are separated by an extrographic procedure, and the obtained fractions are analysed by gas chromatography-mass spectrometry (g.c.-m.s.). The basic part of the identified compounds are derivatives of phenol, guaiacol, veratrol, syringol, resorcinol, free fatty acids and esters of fatty acids. The comparative study of the pyrolysis products of apricot stones and coconut shells reveals some differences, referring mainly to the lipid parts of the raw materials.
