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 (N2, H2, CO2 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 kJ/L to investigate the optimal removal of tar analogue. The maximum removal of toluene was 89.1% using N2 as carrier gas at 8.5 kJ/L and 1.43 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 < CO2 < H2 < N2. Moreover, the distribution of products depends on the nature of the carrier gas as well. However, lower hydrocarbons (LHC) (<C7) and solid residues were observed in each carrier gas. The maximum yield of LHC was about 10.8% in H2 carrier gas, whereas in CO and CO2 it remained below 1% even at 8.5 kJ/L.

非热等离子体在CO,CO 2,H 2和N 2载气中分解生物质气化焦油化合物的比较

在这项研究中,使用介电势垒放电(DBD)反应器研究了甲苯的比较分解。在纯CO气体中研究了焦油模型化合物的首次分解。研究了气化炉产物气中存在的每种载气(N 2,H 2,CO 2和CO)对焦油类似物(甲苯)的分解和产物分布的影响。比输入能量(SIE)也从2.5到8.5 kJ / L不等,以研究焦油类似物的最佳去除效果。使用N 2时,甲苯的最大去除率为89.1%以8.5 kJ / L和1.43 s作为载气。但是,在相同条件下,使用CO载气的最低甲苯去除率为62.5%。甲苯在不同载气中的分解顺序如下:CO <CO 2  <H 2  <N 2。此外,产物的分布也取决于载气的性质。但是,在每种载气中均发现了低级烃(LHC)(<C 7)和固体残留物。在H 2载气中,LHC的最大收率约为10.8%,而在CO和CO 2中,即使在8.5 kJ / L时,LHC的最大收率仍低于1%。
