在两级固定床反应器中进行了煤挥发分制取燃料气的基础研究。煤的干馏挥发分在反应器中分解。印尼天然褐铁矿石在873- 1023 K常压下显著促进煤的挥发分分解，除焦油外，碳产率均在97.8%以上。我们将这些结果与没有催化剂的实验进行了比较。随后，煤焦油转化更完全，并且使用褐铁矿催化剂获得超过两倍量的富甲烷产物气体。此外，在923 K下，H_2S-H_2-N_2（H_2S/H_2：0.002-0.004）体系中几乎没有观察到催化剂硫中毒现象。
Basic research on fuel gas production from nascent coal volatiles was conducted in a two-stage fixed-bed reactor. The volatiles from coal carbonization decomposed in the reactor. Indonesian natural limonite ore dramatically promoted coal volatile decomposition at 873–1023K in ambient pressure and the carbon yields, except in tar, were above 97.8%. We compared these results to experiments without a catalyst. Subsequently, coal tar converted more completely and more than twice the amount of methane-rich product gases were obtained using the limonite catalyst. In addition, catalyst sulphur poisoning was scarcely observed in the H2S–H2–N2(H2S/H2: 0.002–0.004) system at 923K.
