Abstract:
Nowadays only little information (mainly by GCMS) about the chemical nature of HTL oils is available. In the present work different standard and improved analytical techniques were tested as additional tools for the chemical characterization of HTL oils: analytical pyrolysis (PyGCMS), TGA and a novel stepwise PySPMEGCMS were tested for the first time. By coupling these different techniques, we could establish the chemical nature of the fractions not amenable for standard oil analysis techniques (GCMS, silylation or transesterification). In the case of 200°C HTL the high molecular weight substances mainly consisted in algaenans derived materials, whereas a low amount of proteins (or protein containing macromolecules) ended up in the HTL oil. In the case of 300°C HTL oil, the mass fraction of the HTL products originated from nonlipidic material degradation as well as “protein” content of the oil were identified and the resulting high nitrogen content present in the 300°C HTL oil was explained.
