“…It was already shown that Ni-based catalysts prepared by incipient wetness impregnation were active and stable when they were tested in the gas phase MA hydrogenation and subsequent SA hydrogenolysis at atmospheric pressure [17][18][19]. Additionally, the effect of the support used on these Ni-based catalysts was studied, finding that SiO 2 -Al 2 O 3 was the most stable and selective to obtain GBL [18].…”

“…Additionally, the effect of the support used on these Ni-based catalysts was studied, finding that SiO 2 -Al 2 O 3 was the most stable and selective to obtain GBL [18]. Moreover, it was shown that the optimum Ni metal load to obtain GBL was 10 % when SiO 2 -Al 2 O 3 was used as a support [19]. It was also found that the reaction scheme over Ni catalysts involves the selective hydrogenation of MA to SA, followed by hydrogenolysis of SA to give GBL and/or PA along with CO.…”

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.

“…However, because of their weak hydrogenation ability towards the C=O bond of Ni [10,11], hydrogenation products are mostly mixtures of SA and GBL. Some valuable strategies have been employed to regulate the selectivity of Ni-based catalysts [12,13,14,15,16], such as introducing a second component as a promoter and modifying surface acid-base properties of supports. Results of experiments have also shown that these are effective regulation methods.…”

ZrO2 nanoparticles, ZrO2 (P) and ZrO2 (H), with different tetragonal phase contents, were prepared. ZrO2 (P) possessed higher tetragonal phase content than ZrO2 (H). Ni/ZrO2 catalysts (10% (w/w)), using ZrO2 (P) and ZrO2 (H) as supports, were prepared using an impregnation method, and were characterized using XRD, Raman, H2-TPR, XPS, and H2-TPD techniques. Their catalytic performance in maleic anhydride hydrogenation was tested. The Ni/ZrO2 (P) catalyst exhibited stronger metal-support interactions than the Ni/ZrO2 (H) catalyst because of its higher number of oxygen vacancies and the low-coordinated oxygen ions on its surface. Consequently, smaller Ni crystallites and a higher C=C hydrogenation activity for maleic anhydride to succinic anhydride were obtained over a Ni/ZrO2 (P) catalyst. However, the C=O hydrogenation activity of Ni/ZrO2 (P) catalyst was much lower than that of the Ni/ZrO2 (H) catalyst. A 43.5% yield of γ-butyrolacetone was obtained over the Ni/ZrO2 (H) catalyst at 210 °C and 5 MPa of H2 pressure, while the yield of γ-butyrolactone was only 2.8% over the Ni/ZrO2 (P) catalyst under the same reaction conditions. In situ FT-IR characterization demonstrated that the high C=O hydrogenation activity for the Ni/ZrO2 (H) catalyst could be attributed to the surface synergy between active metallic nickel species and relatively electron-deficient oxygen vacancies.

“…The metal catalysts Pd, Ru, Cu, and Ni are widely accepted as being active in the hydrogenation of MA [3,[5][6][7][8]. They are usually supported on metal oxides (for example, Al 2 O 3 , SiO 2 , diatomite, SiO 2 -Al 2 O 3 , and zeolite) [9][10][11][12]. Yu et al reported that adding CeO 2 to a Cu-Al 2 O 3 catalyst supported the hydrogenation of MA to GBL [13].…”

A series of Sc-doped ZrO2 supports, with Sc2O3 content in the range of 0 to 7.5% (mol/mol), were prepared using the hydrothermal method. Ni/Sc-doped ZrO2 catalysts with nickel loading of 10% (w/w) were prepared using impregnation method, and characterized with the use of XRD, Raman, H2 temperature-programmed reduction (H2-TPR), H2 temperature-programmed desorption (H2-TPD), XPS, and in situ FT-IR techniques. The catalytic performances of Ni/Sc-doped ZrO2 catalysts in maleic anhydride hydrogenation were tested. The results showed that the introduction of Sc3+ into ZrO2 support could effectively manipulate the distribution of maleic anhydride hydrogenation products. γ-butyrolactone was the major hydrogenation product over Sc-free Ni/ZrO2 catalyst with selectivity as high as 65.8% at 210 °C and 5 MPa of H2 pressure. The Ni/Sc-doped ZrO2 catalyst, with 7.5 mol% of Sc2O3 content, selectively catalyzed maleic anhydride hydrogenation to succinic anhydride, the selectivity towards succinic anhydride was up to 97.6% under the same reaction condition. The results of the catalysts’ structure–activity relationships revealed that there was an interdependence between the surface structure of ZrO2-based support and the C=O hydrogenation performance of the ZrO2-based supported nickel catalysts. By controlling the Sc2O3 content, the surface structure of ZrO2-based support could be regulated effectively. The different surface structure of ZrO2-based supports, resulted in the different degree of interaction between the nickel species and ZrO2-based supports; furthermore, the different interaction led to the different surface oxygen vacancies electron properties of ZrO2-based supported nickel catalysts and the C=O hydrogenation activity of the catalyst. This result provides new insight into the effect of ZrO2 support on the selective hydrogenation activity of ZrO2-supported metal catalysts and contributes to the design of selective hydrogenation catalysts for other unsaturated carbonyl compounds.
