In this research, a dielectric barrier discharge (DBD) reactor is used to study the cracking of the toluene into C-C hydrocarbons. The combined effect of parameters such as temperature (20-400 °C) and plasma power (10-40 W) was investigated to evaluate the DBD reactor performance. The main gaseous products from the decomposition of toluene include lower hydrocarbon (C-C). The cracking of toluene increases with power at all temperatures (20-400 °C). On the otherhand, it decreases from 92.8 to 73.1% at 10 W, 97.2 to 80.5% at 20, 97.5 to 86.5% at 30 W, and 98.4 to 93.7% at 40 W with raising the temperature from 20 to 400 °C. Nonetheless, as the temperature and plasma input power increase, the methane yield increases. At 40 W, the maximum methane yield was 5.1%. At 10 and 20 W, the selectivity to C increases as the temperature rises up to 400 °C. At 30 and 40 W, it began to drop after 300 °C due to the formation of methane and the yield of methane increases significantly beyond this temperature.
在本研究中,使用介质阻挡放电(DBD)反应器来研究甲苯裂解为碳 - 碳烃类的过程。研究了温度(20 - 400°C)和等离子体功率(10 - 40W)等参数的综合影响,以评估DBD反应器的性能。甲苯分解产生的主要气态产物包括低碳烃(碳 - 碳)。在所有温度(20 - 400°C)下,甲苯的裂解率随功率增加而提高。另一方面,随着温度从20°C升高到400°C,在10W时,裂解率从92.8%降至73.1%;在20W时,从97.2%降至80.5%;在30W时,从97.5%降至86.5%;在40W时,从98.4%降至93.7%。尽管如此,随着温度和等离子体输入功率的增加,甲烷产率增加。在40W时,最大甲烷产率为5.1%。在10W和20W时,随着温度升高至400°C,对碳的选择性增加。在30W和40W时,由于甲烷的形成,在300°C后选择性开始下降,且超过该温度后甲烷产率显著增加。
