This work investigates the potentials of peat and angico hardwood sawdust to remove BTEX (benzene, toluene, ethylbenzene, and isomers of xylene) from the produced water discharged into aquatic systems during petroleum extraction. Peat and angico sawdust samples were pyrolyzed at 500°C, and found to contain n-alkenes, n-alkanes and pentacyclic triterpenes (peat), and 4-methoxyphenol, 1,4-dimethoxyphenol and 1,3,4-trimethoxyphenol (angico sawdust). In batch experiments, the removal capacities using peat were 32.4%, 50.0%, 63.0%, 67.8%, and 61.8% for benzene, toluene, ethylbenzene, m,p-xylenes and o-xylene, respectively. This compared with removal capacities using angico sawdust of 20.2%, 36.4%, 52.8%, 57.8%, and 53.7% for these compounds respectively, demonstrating the superior performance of the peat.
本研究旨在探讨泥炭和金合欢硬木锯末在去除采油过程中排入水生系统的生产水中 BTEX（苯、甲苯、乙苯和二甲苯异构体）方面的潜力。对泥炭和金合欢锯末样品在 500°C 下进行热解，发现它们分别含有正烯烃、正烷烃和五环三萜（泥炭）以及 4-甲氧基苯酚、1,4-二甲氧基苯酚和 1,3,4-三甲氧基苯酚（金合欢锯末）。在批量实验中，泥炭对苯、甲苯、乙苯、间二甲苯和对二甲苯的去除率分别为 32.4%、50.0%、63.0%、67.8%和 61.8%，而金合欢锯末的去除率分别为 20.2%、36.4%、52.8%、57.8%和 53.7%，表明泥炭的性能更优。
