Abstract:
Hydrogen production by catalytic steam reforming of the bio-oil, naphtha, and CH4 was investigated over a novel metal-doped catalyst of (Ca24Al28O64)4+¢4O-/Mg (C12A7-Mg). The catalytic steam reforming was investigated from 250 to 850 ±C in the ˉxed-bed continuous °ow reactor. For the reforming of bio-oil, the yield of hydrogen of 80% was obtained at 750 ±C, and the maximum carbon conversion is nearly close to 95% under the optimum steam reforming condition. For the reforming of naphtha and CH4, the hydrogen yield and carbon conversion are lower than that of bio-oil at the same temperature. The characteristics of catalyst were also investigated by XPS. The catalyst deactivation was mainly caused by the deposition of carbon in the catalytic steam reforming process.

摘要:
利用自制的C12A7-Mg催化剂,研究了催化水蒸汽重整生物油、石脑油和CH4制备氢气的性能,以及催化剂寿命,并用X射线光电子能谱对催化剂进行了表征.温度测试范围为250?850 ℃.对于催化水蒸汽重整生物油反应,在750 ℃时,氢气产率最大达到80%,碳的转化率接近95%.在相同的反应温度下,催化水蒸汽重整石脑油和CH4的氢气产率和碳的转化率要低于重整生物油反应.催化剂的失活主要是由于重整过程中的积碳.
