We report here the synthesis and testing of a set of 48 alumina-supported catalysts for hydrogenation of 5-ethoxymethylfurfural. This catalytic reaction is very important in the context of converting biomass to biofuels. The catalysts are composed of one main metal (gold, copper, iridium, nickel, palladium, platinum, rhodium, ruthenium) and one promoter metal (bismuth, chromium, iron, sodium, tin,
我们在此报告了一组用于48种氧化铝负载的5-乙氧基甲基糠醛加氢催化剂的合成和测试。在将生物质转化为生物燃料的背景下,该催化反应非常重要。催化剂由一种主要金属(金,铜,铱,镍,钯,铂,铑,钌)和一种助催化剂金属(铋,铬,铁,钠,锡,钨)组成。使用16平行滴流式反应器,我们在各种条件下测试了所有48种催化剂组合。结果表明,底物转化率和产物选择性均对温度变化和溶剂效应敏感。使用铱/铬(Ir / Cr)催化剂可获得所需产物> 5-乙氧基甲基糠醇> 99%收率的最佳结果。
