    摘要： 一种丙酮加氢产物分离系统，包括一粗分塔、膜进料过热器、无机渗透膜、产品冷凝器、渗透液冷凝器、气相真空泵、尾气冷凝器；所述粗分塔通过下部侧采线与膜进料过热器冷物料入口连接，膜进料过热器的热物料出口线与无机渗透膜进料口连接；无机渗透膜通过产品出料线与产品冷凝器热物料入口连接；无机渗透膜通过渗透液线与渗透液冷凝器热物料入口连接，渗透液冷凝器的气相出口线与气相真空泵入口连接，气相真空泵出口线尾气冷凝器入口连接。上述分离系统因采用了无机渗透膜代替萃取及脱水塔进行脱水，极大地缩短了分离流程，降低了蒸汽消耗，且无需萃取剂，既节能又环保。

    摘要： A process is described for producing biobased 1,2-propanediol, comprising reacting a glycerol-containing feed containing less than 5 weight percent of water with hydrogen in the presence of a catalyst, to partially convert glycerol in the glycerolcontaining feed to a crude reaction product mixture including 1,2-propanediol, removing 10 water from the crude reaction product mixture, recovering a portion but not all of the 1,2-propanediol from the crude reaction product mixture, and recycling the remainder of the 1,2-propanediol with unconverted glycerol and combining these with makeup glycerol to provide additional of the essentially anhydrous, glycerol-containing feed.
