    • The invention provides a process for the preparation of glycols from a saccharide-containing feedstock in a reactor system, said process comprising: i) providing a first feed stream comprising said saccharide-containing feedstock in a first solvent at a temperature of no more than 160°C; ii) providing a second feed stream comprising a tungsten- based retro-aldol catalytic species and an alkali metal containing species in a second solvent at a temperature in the range of from 150 to 250°C; iii) combining the first feed stream and the second feed stream, before they are provided to the reactor system, to form a combined feed stream; iv) providing the combined feed stream to the reactor system and operating the reactor at a temperature in the range of from 150°C to 250°C; and v) also contacting the combined feed stream with a hydrogenation catalytic species in the presence of hydrogen, wherein the molar ratio of alkali metal:tungsten in the combined feed stream is in the range of from 0.55 to 6.
    • 本发明提供了一种在反应器系统中由含糖原料制备二醇的方法,所述方法包括:i)提供包含所述含糖原料的第一进料流在第一溶剂 在不超过160℃的温度下; ii)在150-250℃的温度下,在第二溶剂中提供包含钨基逆向醛Aldol催化物质和含碱金属物质的第二进料流; iii)在将第一原料流和第二原料流提供给反应器系统之前将第一原料流和第二原料流组合以形成合并的原料流; iv)将合并的进料流提供给反应器系统并在150℃至250℃的温度下操作反应器; 和v)还在氢气存在下使合并的进料物流与氢化催化物质接触,其中合并进料物流中碱金属:钨的摩尔比在0.55-6的范围内。
