Ethanol steam reforming of synthetic bioethanol (i.e., anhydrous ethanol plus water), as well as bioethanol obtained from glucose standards and sugarcane press-mud was evaluated on monoliths washcoated with RhPt/CeO₂–SiO₂. Tests with synthetic bioethanol indicated that the lower pressure drop favors higher ethanol conversion in the monoliths with respect to the powder samples. Also, two monoliths in series with 0.08 g_cat/cm³ improved H₂ yield compared to just one monolith with 0.16 g_cat/cm³. Similarly, a decrease in the amount of carrier gas contributes to diffusion limitations in the monoliths, reducing the H₂/CO ratio. Monoliths stability was also evaluated with “real” bioethanol samples (from glucose standards and sugarcane press-mud-SPM). In all cases, a syngas with >60% of H₂ was produced. For SPM-bioethanol, 3.1 ± 0.2 mol H₂/mol EtOH were obtained without evidence of deactivation for 120 h, at a cost of 6.9 $/kgH₂, becoming a promising way to develop a technology for sustainable energy production.

在用RhPt / CeO ₂ -SiO ₂修补的整料上评估了合成生物乙醇（即无水乙醇加水）的乙醇蒸汽重整，以及从葡萄糖标准品和甘蔗压泥获得的生物乙醇。合成生物乙醇的测试表明，相对于粉末样品，较低的压降有利于整体料中较高的乙醇转化率。而且，与仅一个具有0.16g _cat / cm ^3的整体物相比，两个具有0.08g _cat / cm ^{3的整体物}提高了H ₂产率。同样，载气量的减少也有助于整体材料中的扩散限制，从而降低了H ₂/ CO比。还使用“真实的”生物乙醇样品（来自葡萄糖标准品和甘蔗压泥-SPM）评估了整料的稳定性。在所有情况下，用H> 60％合成气₂被制造。对于SPM-生物乙醇，在没有证据表明失活120小时的情况下，获得了3.1±0.2 mol H ₂ / mol EtOH，成本为6.9 $ / kgH ₂，成为开发可持续能源生产技术的一种有前途的方法。
