摘要： This research investigated the feasibility of enhanced energy yield in gasification of rice straw by using a prepared iron-based catalyst. The prepared iron-based catalyst containing 2% (wt%) Fe2O3 was produced by wet impregnation process. Based on the results of produced gas yield, the yield amounts of combustible gases increased with an increase in the prepared iron-based catalyst addition. In the case of gasification temperature 800 °C and below, the yield amount of combustible gas increased by using the prepared iron-based catalyst. Besides, the energy yield efficiency was approximately enhanced from 8% to 74% with the iron-based catalyst addition. In the case of gasification temperature 800 °C and iron-based catalyst addition, the energy yield efficiency of combustible gases is similar with that of gasification temperature 900 °C and without catalyst addition. That is, prepared iron-based catalyst has the good potential for converting rice straw into bio-energy and for reducing the energy requirement in gasification. •The iron-based catalyst containing 2% (wt%) Fe2O3 was well-prepared by wet impregnation process.•The prepared iron-based catalyst could promote water-gas shift reaction resulted in H2/CO ratio increasing at 800 °C.•The tested iron-based catalyst has good potentials for enhancing quality of combustible gas. 出版者： Elsevier Ltd 出版日期： 2016-12-14 出處： International journal of hydrogen energy, 2016-12, Vol.41 (46), p.21747-21754 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2016 Hydrogen Energy Publications LLC 識別號： ISSN: 0360-3199 識別號： EISSN: 1879-3487 識別號： DOI: 10.1016/j.ijhydene.2016.08.021
