چکیده
in the present study, the effects of calcium doping on the performance of the co-precipitated cu-mgo catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. the results proved that the addition of this promoter had a remarkable impact on the catalytic performance. the conversion of furfuraldehyde enhanced up to 83% and the furfuryl alcohol selectivity remained above 96% over the run length on the promoted cu-ca-mgo catalyst. however, the conversion level decreased to 60% after 240 min of operation period which was still superior with respect to the negligible conversion with the non-promoted cu-mgo catalyst.

Effect of Calcination Rate on Performance of Co-precipitated Cu-MgO Catalyst in Hydrogenation of Furfural
Co-precipitated Cu-MgO catalysts were prepared and evaluated for the gas-phase hydrogenation of furfural. The effect of heating rate at the calcination step was studied by comparing the performance of three catalysts prepared via the same procedure but calcined at different heating rates. The results established that altering the heating rate could influence the structural properties of the cat...
