Abstract

The purpose of this study was to develop a technology that can convert biogas to synthesis gas (SynGas), a low-emission substituted energy, using a non-thermal-pulsed plasma method. To investigate the characteristics of SynGas production from simulated biogas, the reforming characteristics in relation to variations in pulse frequency, biogas component ratio (C3H8/CO2), vapor flow ratio (H2O/total flow rate [TFR]), biogas velocity, and pulse power were studied. A maximum conversion rate of 49.1% was achieved for the biogas when the above parameters were 500 Hz, 1.5, 0.52, 0.32 m/sec, and 657 W, respectively. Under the above conditions, the dry basis mole fractions of the SynGas were as follows: H2 = 0.645, CH4 = 0.081, C2H2 = 0.067, C3H6 = 0.049, CO = 0.008 and C2H4 = 0.004. The ratio of hydrogen to the other intermediates in the SynGas (H2/ITMs) was 3.1.

摘要

本研究的目的是开发一种技术，该技术能够使用非热脉冲等离子体方法将沼气转化为合成气（合成气），一种低排放的替代能源。为了研究模拟沼气生产合成气的特性，研究了与脉冲频率、沼气成分比（C3H8/CO2）、蒸汽流量比（H2O/总流量[TFR]）、沼气速度和脉冲功率变化相关的重整特性。当上述参数分别为500Hz、1.5、0.52、0.32m/秒和657W时，沼气的最大转化率达到49.1%。在上述条件下，合成气的干基摩尔分数如下：H2 = 0.645，CH4 = 0.081，C2H2 = 0.067，C3H6 = 0.049，CO = 0.008，C2H4 = 0.004。合成气中氢气与其他中间产物的比例（H2/ITMs）为3.1。
