Zeolite Y (zeolite) supported ruthenium (Ru) catalyst, Ru/zeolite, is prepared by simple impregnation method and characterized by using energy dispersive X-ray analysis (EDX), inductively coupled plasma (ICP) mass spectrometry, transmission electron microscopy (TEM), and CO chemisorption. The catalyst Ru/zeolite is evaluated in hydrogenation of D-glucose (Schematic diagram is shown in figure 1) and hydrogenation experiments to produce a selective product D-sorbitol were carried out batch wise in a three- phase laboratory scale reactor. Figure 1. <img src='https://acs-archive-assets2.s3.amazonaws.com/241nm/uploads/69868_abstract_acs_figure.jpg' alt='' /> The kinetics studies of D-Glucose hydrogenation using the catalyst Ru/zeolite were carried out in the absence of mass transfer limitations. In the operating regime studied, the rate of reaction showed first orders dependency with respect to D-glucose and hydrogen also. The kinetic data were modeled by Langmuir�Hinshelwood�Hougen�Watson (LHHW) kinetics, assuming that the surface reaction is rate-determining. For affording maximum D-glucose conversion, yield and selectivity to D-sorbitol, the reaction conditions were also optimized.
