摘要
对在流化床反应器中生物油轻组分模拟物(简称模拟物)与水蒸气催化重整制氢进行了研究。考察了温度、模拟物中H2O与C的摩尔流率之比(S/C)和模拟物的重时空速(WHSV)对催化重整制氢的影响。适宜的反应条件为:工业级镍基催化剂(w(NiO)=7.2%)200g、温度650℃、S/C=11、WHSV=0.7h-1、反应时间3h。在此条件下,H2产率、潜在H2(H2+CO)产率和总的C元素选择性达到最大值,分别为89.3%,94.8%,96.3%。SEM表征发现,烧结是造成催化剂失活的原因之一。
Hydrogen production was carried out through catalytic steam reforming of simulacrum of light component of bio-oil in a fluidized bed reactor. Effects of temperature, mole ratio of steam to carbon (S/C) and WHSV of the simulacrum on the reforming were investigated. Under the optimum reaction conditions of industrial-grade nickel-based catalyst (w(NiO) 7.2% ) 200 g, 650 ℃, S/C 11, WHSV 0.7 h - 1 and reaction time 3 h, the hydrogen yield, the potential hydrogen ( H2 + CO) yield and the total carbon selectivity reached 89.3 %, 94.8 % and 96.3 %, respectively. SEM result showed that sintering was one of the reasons of the catalyst deactivation.
