摘要: Abstract In order to secure the feed, a bio-based chemical production plant shall be designed process more than one feedstock. However, usually requires costly H2 supply. Without feeding, effects of Cu on Cu0.3Mg1.7Al-LDO catalysts were investigated hydrogenolysis glycerol with and without bio-ethanol co-feeding. As result, reduced catalyst dramatically increased conversion gave an apparently-high selectivity chemicals such as 1,2-propandiol, ethyl lactate, lactic acid. Apparently, besides hydrogen donor, ethanol also acted reactant that produced lactate via esterification summary, Cu2+ Cu+ sites promoted dehydration, oxidation acid, whereas Cu0 was believed promote in-situ formation from reforming. The integrated reaction pathways proposed discussed.
