The behavior of aliphatic hydrocarbons during co-composting of sewage sludge activated with palm tree waste was studied for 6 months using Py-GC/MS. The main aliphatic compounds represented as doublet alkenes/alkanes can be classified into three groups. The first group consists of 11 alkenes (undecene, tridecene, pentadecene, hexadecene, heptadecene, octadecene, nonadecene, eicosene, uncosene, docosene, tricosene) and 15 alkanes (heptane, octane, nonane, decane, undecane, dodecane, tetradecane, pentadecane, heptadecane, octadecane, nonadecane, eicosane, uncosane, docosane, and tricosane), which remain stable during the co-composting process. The stability of these compounds is related to their recalcitrance behavior. The second group consists of five alkenes (heptene, octene, nonene, decene, dodecene) and tridecane as a single alkane that decreases during co-composting. The decrease in these compounds is the combined result of their metabolism and their conversion into other compounds. The third group is constituted with tetradecene and hexadecane that increase during composting, which could be explained by accumulation of these compounds, which are released by the partial breakdown of the substrate. As a result, these molecules are incorporated or adsorbed in the structure of humic substances.
采用 Py-GC/MS 研究了棕榈树废物活化的污水污泥共堆肥过程中脂肪烃的行为，共研究了 6 个月。主要的脂肪族化合物表现为双键烯烃/烷烃，可分为三组。第一组由 11 种烯烃（十一烯、十三烯、十五烯、十六烯、十七烯、十八烯、十九烯、二十烯、二十碳烯、二十二烯、二十三烯）和 15 种烷烃（庚烷、辛烷、壬烷、癸烷、十一烷、十二烷、十四烷、十五烷、十七烷、十八烷、十九烷、二十烷、二十一烷、二十二烷、二十三烷）组成，这些化合物在共堆肥过程中保持稳定。这些化合物的稳定性与其难降解行为有关。第二组由五种烯烃（庚烯、辛烯、壬烯、癸烯、十二烯）和十三烷作为一种单独的烷烃组成，在共堆肥过程中减少。这些化合物的减少是其代谢和转化为其他化合物的综合结果。第三组由十四烯和十六烷组成，在堆肥过程中增加，这可以解释为这些化合物的积累，这些化合物是由基质的部分分解释放出来的。因此，这些分子被包含或吸附在腐殖质的结构中。
