摘要：

Kinetic evaluations were accomplished in a discontinuous three-phase reactor for saccharose, glucose and fructose hydrogenations at 373, 393 and 413 K, and 24 atm. Selectivities attained values in the order of 99.05%. Langmuir-Hinshelwood models based on heterogeneous mechanisms were proposed and the optimization and kinetic quantification of the process were performed.
