The large proportion of phenols in the pyrolyzate of this sample may be explained by the abundance of lignin.
The pyrolyzate of sample NO-3 was dominated by carbohydrate markers, with acetic acid, 3/2-furaldehyde, 5methyl-2-furaldehyde, dianhydro-a-glucopyranose, a furanone and 4-acetylfuran accounting for 62% of TQPA (Table 2).
In general, the differences in pyrolyzate compositions between NO-samples and MN-samples were small, yet some are worth mentioning.
The origin of PAHs in SOM pyrolyzates have been the subject of considerable debate.
Pyrroles, pyridines and indoles are potential products of BN as well, but these compounds are common in the pyrolyzates of non-pyrogenic N-moieties.
The infrared examination of pyrolyzate can identify a mixture of two types of rubber in the range from 80% major component to 20% minor component.
The Rock-Eval 6 determines the TOC by summing the carbon in pyrolyzate with that obtained by oxidizing the residual organic matter at 650[degrees]C [21].
