| 摘 要： | 对生物质燃气中焦油的净化进行试验研究,通过在喷淋塔前设置空冷塔的焦油净化系统,并以稻秸秆为原料考察热解温度对生物质燃气中焦油在空冷塔和喷淋塔中的分配情况及化学组成的影响。结果表明,生物质燃气中80%的焦油可在空冷塔中富集,当热解温度由500℃升至750℃时,空冷塔中焦油的占比由84.26%降至80.55%,喷淋塔中焦油占比由15.74%升至19.45%;生物质焦油中超过99%、81%、84%和93%的酚类化合物、烷烯烃、含氮化合物和含氧化合物(除酚类化合物外)在空冷塔中富集,而超过76%的芳烃及其衍生物在喷淋塔中富集。

| Abstract: | The experimental way of purification of tar from biomass gas producer was studied. By setting spray tower before air-cooling tower and taking rice straw as raw material,the effect of pyrolysis temperature on biomass tar distribution and composition in air-cooling tower and spray tower were investigated. The results show that 80% of biomass tar from gas producer can be enriched in air-cooling tower. The proportion of biomass tar in air-cooling tower decreases from 84.26% to 80.55% and in spray tower increases from 15.74% to 19.45% as temperature increases from 500 ℃ to 750 ℃. The proportion of phenolics,alkane and alkene,nitrogen-containing compounds and oxygen-containing(excluding phenolics)compounds obtained from biomass tar in air-cooling tower are 99%,81%,84% and 93% respectively. And the proportion of aromatic and its derivatives are above 76% in spray tower. |
