摘要： 在热解气体气氛下，通过热解将城市生活垃圾制备高级固体燃料（生物炭）和热解气。该实验是在氮气和热解气两种气氛中，反应温度为600-800°C的填充床反应器中进行的。气体、液体和固体产物通过气相色谱仪和元素分析仪进行分析。两种气氛条件下获得的生物炭产量没有显著差异。热解气中的甲烷和二氧化碳促进了生活垃圾中挥发分的释放，导致挥发分/固定碳的比值降低0.13左右。O/C和H/C的原子比分别约为0.02-0.11和0.005-0.035。这些值与无烟煤类型相同。研究结果显示，热解气体条件下，液体燃料产率高于N2条件下的液体燃料产率。而且，氢气和一氧化碳产量的增加伴随着甲烷和二氧化碳产量的减少。因此，对于生产燃料品质接近无烟煤的生物炭，建议在800°C或更高的温度下进行反应，反应时间应大于4分钟。

Abstract: Municipal Solid Waste (MSW) was converted into high-grade solid fuels (biochar) and gaseous product via thermal pyrolysis under pyrolytic gas atmosphere. The experiment was carried out in a packed-bed reactor at the temperature range of 600–800 °C in both atmospheres of N2 and pyrolytic gas. Gas, liquid, and solid products were analyzed by gas chromatograph and elemental analysis. Amount of biochar obtained from both atmospheres were not significantly different. CH4 and CO2 in pyrolytic gas promoted the release of volatile in the MSW, resulting in lower ratio of VM/FC, ca. 0.13. The atomic ratios of O/C and H/C were around 0.02–0.11 and 0.005–0.035, respectively. These values were equivalent to anthracite coal type. On the other hand, the liquid fuel yield under pyrolytic gas condition was found to be higher, compared with that under N2 condition. In addition, the enhancement of H2 and CO production was accompanied by the decrease in CH4 and CO2 output. Overall, the operating condition at 800 °C or higher with reaction times longer than 4 min were recommended for production of biochar with fuel qualities approaching anthracite coal.
