Collection description

Synthesis, characterising data and catalytic data for a set of Ni/Al2O3 hydrogenation catalysts prepared from a hydrotalcite precursor The catalytic response of Ni on alumina obtained from Ni-Al layered double hydroxides was studied for the liquid phase hydrogenation of hydroxymethyl furfural to tetrahydrofuran-2,5-diyldimethanol in water. The successive calcination and reduction of the precursors caused the removal of interlayer hydroxyl and carbonate groups and the reduction of Ni2+ to Ni0. Four reduced mixed oxide catalysts were obtained, consisting of different nickel metal (47-68 wt%) on an Al-rich amorphous component. The catalytic activity was linked to Ni content while selectivity was mainly affected by reaction temperature. Tetrahydrofuran-2,5-diyldimethanol is formed in a stepwise manner at low temperature (353 K) while 3-hydroxymethyl cyclopentanone is generated at higher temperature. Coke formation causes deactivation, however catalytic activity can be regenerated with heat treatment. The results establish Ni on alumina as a promising catalyst for the production of tetrahydrofuran-2,5-diyldimethanol in water.
