Abstract

An experimental investigation has been conducted to study diesel fuel reforming by a recirculation type electrohydrodynamic atomization system (REHDA). The fuel in the EHD atomization system was injected through a hollow tube electrode that was powered using a high voltage pulse power supply. A hollow ring on the ceramic holder for the hollow tube served as the ground electrode. Experiments were performed for diesel fuel with a flow rate of 4 mL/min. The fuel was recirculated through the EHD atomization system 1 to 5 times. The maximum applied voltage varied from 0 to 26 kV at a pulse repetition rate of 200 Hz. The liquid by-products from the REHDA system were analyzed using a GC. The results showed the REHDA could achieve significant cracking of the large CxHy components to the decane level.

再循环型脉冲电压电流体动力雾化重整柴油
采用再循环型电液动力雾化系统(REHDA)对柴油进行了重整实验研究。EHD雾化系统中的燃料通过一个空心管电极注入,该电极由高压脉冲电源供电。空心管的陶瓷支架上的空心环作为接地电极。实验以柴油为原料,流速为4 mL/min。燃料通过EHD雾化系统再循环1 ~ 5次。以200赫兹的脉冲重复率,最大施加电压从0到26千伏不等。采用气相色谱法对REHDA系统的液体副产物进行了分析。结果表明,REHDA能将大的CxHy组分裂解至十烷水平。
