流态化床内糠醛气相加氢制糠醇

进行了流态化床中糠醛气相催化加氢制糠醇的研究。研究了反应温度、分子比、空间速度对反应的影响。研究结果表明,最适宜的反应条件为:空间流速2.6—3.0升/分/100毫升催化剂,温度140℃,糠醛:氢气（分子比）=1∶40—45。糠醇的单程产率在90％以上,出口混合物中没有未反应的糠醛。

VAPOR-PHASE HYDROGENATION OF FURFURAL TO FURFURYL ALCOHOL IN A FLUIDIZED BED

Investigations have been made on the catalytic hydrogenation of furfural to furfuryl alcohol in a fluidized bed. Effects on the reaction of the variables such as temperature, inlet gas composition and space velocity have been studied. The optimum reaction conditions as shown by the experimental results are: temperature 140℃, space velocity 2.6-3.0 liter/(min. ×100 ml. catalyst), and inlet gas composition (molar ratio of furfural to hydrogen) 1: 40-45. The once-through yield of furfuryl alcohol is greater than 90%, and the outlet mixture contains no any unreacted furfural.
