| 摘 要： | 比较了不使用催化剂和使用商业催化剂Z204时生物油水相重整制氢反应的特点,研究了催化剂的还原时间和反应温度对生物油水相重整制氢反应的影响,考察了催化剂的寿命和反应器阻力增大的原因。实验结果表明,使用Z204催化剂时,H2收率最高可达58%,明显高于不加催化剂时的H2收率;在催化剂还原时间1.0h、反应温度750℃的条件下,反应30min后H2收率达到42%,随后略有下降,在540min的反应时间内H2收率基本维持在35%左右。反应过程中生成的碳渣使反应器阻力增大,碳渣是由积碳和含有Fe,Ca,Al,Pb,Mn,Si,Na,Mg等无机元素的灰分组成的。 |

| Abstract: | Hydrogen production by reforming of bio-oil in aqueous solution on commercial catalyst Z204 was focused on.Effects of catalyst reduction time and reaction temperature on the reforming were studied.Lifetime of Z204 catalyst and problem of resistance increase in reactor were investigated.Maximum H2 yield can reach as high as 58%,evidently higher than that without catalyst.Under conditions of reaction temperature 750 ℃ and catalyst reduction time 1.0 h,H2 yield is 42% after 30 min,and keeps at about 35% for the next 540 min.The resistance increase in reactor is mainly due to carbon residue containing inorganic ash of Fe,Ca,Al,Pb,Mn,Si,Na and Mg. |
