A comparison of the decomposition of biomass gasification tar compound in CO, CO2, H2 and N2 carrier gases using non-thermal plasma

In this study, a comparative decomposition of toluene was investigated using a dielectric barrier discharge (DBD) reactor. The first-time decomposition of the tar model compound was investigated in pure CO gas. The effect of each carrier gas (N-2, H-2, CO2 & nbsp;and CO), which exists in product gas from the gasifier, was studied on the decomposition of tar analogue (toluene) and product distribution. The specific input energy (SIE) was also varied from 2.5 to 8.5 & nbsp;kJ/L to investigate the optimal removal of tar analogue. The maximum removal of toluene was 89.1% using N-2 & nbsp;as carrier gas at 8.5 & nbsp;kJ/L and 1.43 & nbsp;s. However, the minimum removal of toluene was 62.5% using CO carrier gas under the same conditions. The decomposition of toluene in different carrier gases was in the following order: CO & nbsp;<& nbsp;CO2 & nbsp;<& nbsp;H-2 & nbsp;<& nbsp;N-2. Moreover, the distribution of products depends on the nature of the carrier gas as well. However, lower hydrocarbons (LHC) (

Automated summary

This study investigated the comparative decomposition of toluene using a dielectric barrier discharge (DBD) reactor, focusing on the impact of different carrier gases (N-2, H-2, CO2, and CO) on toluene removal. Results showed that the highest toluene removal rate of 89.1% was achieved when using N-2 as the carrier gas, while the lowest removal rate of 62.5% was observed when using CO as the carrier gas.
