Pirmoradi, Maryam; Janulaitis, Nida; Gulotty, Robert J. Jr; Kastner, James R. published the artcile< Bi-Metal-Supported Activated Carbon Monolith Catalysts for Selective Hydrogenation of Furfural>, SDS of cas: 97-99-4, the main research area is bi metal supported carbon monolith catalyst hydrogenation furfural.
Activated carbon monolith (ACM) catalysts were impregnated with Pd, Pd-Cu, and Pd-Fe for continuous hydrogenation of aqueous furfural (FUR). The effect of temperature, pressure, and liquid residence time on product selectivity and space-time yield (STY) was determined Adding a second metal to Pd/ACM shifted the selectivity of the catalyst from 2-methylfuran (2MF) and 2-methyltetrahydrofuran (2MTHF) to furfuryl alc. (FA) and tetrahydrofurfuryl alc. (THFA), resp., over the range of tested temperatures and pressures. High STYs of 272 g/Lcat/h (1089 g/kg-cat/h) for THFA and 143 g/Lcat/h (574 g/kg-cat/h) for FA were achieved using Pd-Fe/ACM at 180°C and 300 psig. Similarly, adding Fe increased the FUR, FA, and THFA turnover frequency by a factor of 3, 4, and 60, resp. The effect was not as pronounced when adding Cu. The effect of acetic acid, an impurity present in crude FUR, on FUR conversion and product selectivity was determined The surface area anal. indicated a relatively low loss of surface area over 13 hydrogenation reactions on each catalyst. The presence of a second metal on the monolith catalyst stabilized the Pd particles, reduced the leaching, and altered the product selectivity.
