“…The gas-phase hydrogenation of MA reaction was studied using several types of noble metal-based catalysts, such as Pd, Pt and Au, as well as Cu-based catalyst, both in liquid and gas phase [3][4][5][6][7][8][9][10][11][12][13][14]. Generally, the experiments were performed at temperatures between 190 and 240°C and pressures between 1 and 5 MPa.…”

The gas phase hydrogenation of maleic anhydride (MA) to succinic anhydride (SA) and the subsequent hydrogenolysis to c-butyrolactone (GBL) was studied on SiO 2 -Al 2 O 3 -supported Ni catalysts modified with Cu and prepared by incipient wetness impregnation (Ni-I, CuNi-I) and coprecipitation-deposition (CuNi-PD) methods. The samples were characterized by N 2 adsorption at -196°C, X-ray diffraction, temperature-programmed reduction, transmission electron microscopy and H 2 chemisorption. Catalytic tests were performed between 170 and 220°C at atmospheric pressure in a fixed bed reactor. Crystalline NiO along with a Ni 2? phase strongly interacting with the support was observed in the oxide precursors. The extent of the strongly interacting Ni 2? phase diminishes according to the following pattern: CuNi-PD [ CuNi-I [ Ni-I, along with a proportional rise of the NiO phase. The proportion of small to large metal particles, formed after reduction, followed the same pattern as that observed for the extent of Ni 2? phase. All catalysts were very active in the MA hydrogenation to SA, but displayed distinct performances with respect to the subsequent SA hydrogenolysis. Hydrogenolytic activity and GBL yield increased following the same pattern as that obtained for the extent of Ni 2? phase. In addition, the effect of raising temperature on hydrogenolytic activity was more important in the case of Ni-I and CuNi-I than for CuNi-PD. Furthermore, CuNi-PD was more selective to GBL than CuNi-I. These results showed that there is an important effect of Cu addition and preparation method on both the structure and catalytic performance of the metal Ni phase.

“…The catalytic hydrogenation of MA by copper-based catalyst proceeds via consecutive hydrogenation steps, in which succinic anhydride, GBL, and THF are formed subsequently [19]. The resultant succinic anhydride can react with the solvent, ethanol, to produce diethyl succinate (DS).…”

“…Hydrogenation of MA can be catalyzed by various kinds of catalysts, such as noble metals (Pd, Re, and Ru) in liquid phase at pressures between 1 and 5 MPa and temperatures between 190 and 240 8C [2,[13][14][15][16], copper-based catalysts in liquid phase at pressures between 5 and 9 MPa and temperatures between 200 and 240 8C [13,17], and copper-based catalysts in gas phase at pressures from 0.1 to 1 MPa and temperatures between 210 and 280 8C [12,18,19]. The gas phase hydrogenation of MA commonly used Cu-Zn-M (M = Al, Cr, Ce, Ti) catalysts.…”

“…Studies have been carried out both in liquid [3,[12][13][14][15][16][17][18][19][20] and gas phase [4,[21][22][23][24][25][26][27][28][29], as well as in supercritical CO 2 medium [30,31]. The liquid-phase hydrogenation of MA requires high temperatures and hydrogen pressures to obtain substantial GBL yields, and in most cases the use of solvents is needed.…”
