| Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 103 === By following Zeng et al. (2012)’s work, the process of CDCL is simulated by Aspen Plus® with R-Gibbs module for the fuel reactor, air reactor, and hydrogen generator. And the type of moving-bed reactor is also selected in this paper.
The objective of this paper is to observe the effects of syngas conversion, operating temperature and pressure in fuel reactor. And also, the maximum hydrogen production rate is investigated under three kinds of coal, Pocahontas No.3 (86.15 wt%), Illinois No.6 (63.75 wt%), and Powder River Basin (PRB , 50.23 wt%). The results are shown that hydrogen production rate is proportional to the carbon content in each kind of coal. However, the phenomenon of the oxygen-carrier temperature at the top of air reactor is reverse proportionally to the carbon content. Finally, the optimal amount of oxygen-carrier and the operating condition of this CDCL process can be found in this work.
