The characteristics of the catalytic hydrogasification of activated carbon/bituminous char/anthracite char with the different catalysts were studied in a pressurized thermogravimetry analysis (PTGA). The GC, BET were used to characterize the physical structure and chemical reaction process of carbon, and the function principle of Co to the carbon-hydrogen reaction was preliminarily obtained. The results show that the catalytic activity of transition metals (Fe, Co, Ni) is significantly higher than that of alkali metals and alkaline earth metals in CCHG process. Transition metal CCHG process exists in low temperature (600−750 ℃) and high temperature (> 800 ℃), the emergence of the low temperature catalytic zone can be attributed to the interaction between the transition metal oxide and carbon, then part of carbon structure is activated. The transition metal is embedded in carbon layer structure, the effects of breaking C-C bond and proving the active hydrogen are more effective. Under the conditions of Co catalyst above 850 ℃ and 1 MPa hydrogen pressure, the hydrogen supply of the catalyst can reach saturation, and the catalytic hydrogasification process of carbon is mainly the catalytic bond breaking reaction induced by temperature. The model carbon with high specific surface area and low density has high CCHG activity with the low catalyst load.

用于模型碳加氢的不同催化剂的行为

在加压热重分析（PTGA）中研究了不同催化剂对活性炭/烟煤/无烟煤的催化加氢气化特性。采用GC、BET表征碳的物理结构和化学反应过程，初步得出Co对碳氢反应的作用原理。结果表明，过渡金属（Fe、Co、Ni）在CCHG工艺中的催化活性明显高于碱金属和碱土金属。过渡金属CCHG过程存在于低温（600-750℃）和高温（>800℃），低温催化区的出现可归因于过渡金属氧化物与碳的相互作用，进而部分碳结构被激活。过渡金属嵌入碳层结构中，断裂CC键和证明活性氢的效果更有效。Co催化剂在850 ℃以上和1 MPa氢气压力的条件下，催化剂的供氢可以达到饱和，碳的催化加氢过程主要是温度诱导的催化断键反应。具有高比表面积和低密度的模型碳具有高CCHG活性和低催化剂负载。碳的催化加氢过程主要是温度诱导的催化断键反应。具有高比表面积和低密度的模型碳具有高CCHG活性和低催化剂负载。碳的催化加氢过程主要是温度诱导的催化断键反应。具有高比表面积和低密度的模型碳具有高CCHG活性和低催化剂负载。
