Abstract:

Ni/Al2O3 catalysts were derived from spinel NiAl2O4 with different Ni content ((2.5, 5 and 7.5) wt%). The catalysts were obtained by H2 reduction and were investigated for the low-temperature hydro-genation of maleic anhydride (MA) to produce succinic anhydride (SA). The characterization results showed that Ni0 active sites were mainly derived during the H2 reduction from spinel NiAl2O4. Among the catalysts studied, employing the optimum preparation and reaction conditions with Ni(5%)/Al2O3 yielded the highest catalytic performance. A near-100% conversion of MA and~90% selectivity to SA were achieved at 120℃ and 0.5 MPa of H2 with a weighted hourly space velocity (MA) of 2 h-1.
