| 摘 要： | 本文对不同碳制氢过程进行了热力学分析,比较了相同进料条件下,采用不同过程进行碳制氢时,过程的冷煤气效率以及最终产物组成,并分析了“一步制氢”中温度、压力、不同进料比对最终产物组成的影响。结果表明,直接制氧适宜的气化温度为923-973 K;增加水蒸气分压力(气化压力随之增加),气体产物的量增加;吸收剂有一最佳的量。

| Abstract: | The different processes of hydrogen from coal are compared thermodynamically according to cold gas efficiency and gas composition for the same feedstock. Related to hydrogen directly from coal, the effects of temperature, pressure and mole ratio on the gas composition are predicted. The results show that: the appropriate temperature range for "Direct-Coal-to-Hydrogen" process is 923-973 K. With the increase of steam partial pressure (the gasification pressure increased correspondingly), the total quantity of product gas will increase. There exists an optimum value of absorbent (CaO) proportion in feedstocks for the highest output of the process. |
