摘要
比较了不使用催化剂和使用商业催化剂Z204时两段式反应器生物油水相部分的重整制氢反应的特点,研究了反应温度和生物油水相部分蒸馏温度对生物油水相部分重整制氢反应的影响,考察了催化剂的寿命和蒸馏残渣的特性。实验结果表明,在两段式反应器上使用Z204催化剂时,H2收率最高可达47%,明显高于不加催化剂时的H2收率;在蒸馏温度为200℃、反应温度为750℃的条件下,反应在约4h的反应时间内H2收率基本维持在35%左右。对蒸馏残渣的特性考察表明生物油水相部分蒸馏残渣的变形温度要远高于反应时的温度。
Influence of commercial catalyst Z204 on steam reforming performance of b fraction for hydrogen production was studied using two-stage fixed bed reactor. Effects o distillation temperatures on hydrogen production, as well as the lifetime of the cat characteristics of the hydrogen production dis wi lation residue were investigated. Comparative study ill Z204 catalyst was much higher than that without highest hydrogen yield of 47%. Under the temperature of 200℃, the hydrogen yield k condi ept ab ustrated th Z204 catal io-oil aqueous f reaction and alyst and the at the yield of yst, with the tions of reaction temperature of 750 ℃ and distillation out 35% within 4 h of reaction.
