This study deals with the production and activation of biochars and their use as supports for a series of ruthenium catalysts for hydrogenation of l-arabinose/d-galactose sugar mixture. The synthesized biochars differ in physicochemical properties and surface chemistry influencing ruthenium metal uptake and dispersion and as a consequence its catalytic behaviour. Selectivity exceeding 95% was observed for both hexitols. The catalytic performance of the prepared Ru supported catalysts is also compared to the already known Ru/activated carbon commercial catalyst.

改性生物炭在糖混合物加氢Ru/C催化剂中的结构效应

本研究涉及生物炭的生产和活化及其作为一系列钌催化剂用于l-阿拉伯糖/ d-半乳糖混合物加氢的载体的用途。合成的生物炭在物理化学性质和表面化学方面不同，影响钌金属的吸收和分散，从而影响其催化行为。观察到两种己糖醇的选择性超过 95%。制备的钌负载催化剂的催化性能也与已知的钌/活性炭商业催化剂进行了比较。
