“…Interestingly, higher the loading of cerium, higher was the content of isoparaffins and branched olefins. As we can see from Table , the reaction path way of 1-hexene on the CoMo/γ-Al 2 O 3 catalyst has the following two ways: , (1) hydrogenation saturation of 1-hexene to hexane; and (2) isomerization of the double bond of 1-hexene to form internal olefins. However, the reaction path way of 1-hexene on CoMo/γ-Al 2 O 3 Ce( x ) has three ways: (1) hydrogenation saturation of 1-hexene and its isomers to corresponding paraffins; (2) isomerization of double bond of a little of 1-hexene, turning into internal olefins; and (3) isomerization of the skeleton of 1-hexene to form different branched olefins.…”

The modified CoMo/γ-Al2O3 catalysts with different Ce and/or P loading were prepared by the incipient wetness impregnation method. The catalysts were characterized using X-ray fluorescence spectroscopy, N2-adsorption–desorption, pyridine Fourier transform infrared, H2 temperature-programmed reduction, high-resolution transmission electron microscopy, and X-ray photoelectron spectroscopy. The effect of Ce and/or P on the active phase, acidic properties, and catalytic activity of the CoMo/γ-Al2O3 catalysts were investigated in detail. The results showed that the phosphorus additive can slightly increase the stacking number of MoS2 slabs by reducing the metal–support interaction. Also, the addition of a small amount of cerium (1.75 wt %) not only increased the average slab length and stacking layer number of MoS2 slabs, but also formed new Brønsted acid sites on the support, which efficiently enhance the thiophene hydrodesulfurization (HDS) and olefins isomerization activity of the catalyst. These favorable effects are more obvious in cases where cerium and phosphorus coexist. The CoMo/γ-Al2O3P(2)Ce(1.75) catalyst exhibited the highest thiophene HDS and olefin isomerization conversion values of 98.58 and 19.51%, respectively. The high isomerization activity is able to inhibit the loss of gasoline octane number. Based on the above results, it can be concluded that the synergistic effect between Ce and P can achieve deep desulfurization and minimize the loss of octane number by modulating the acidity of the support and optimizing the active phase of the sulfided catalysts.

“…5 Therefore, in the RADS process, the higher the reaction temperature, the faster the reaction rate and deactivation rate of the adsorbent. At the same time, the side reactions such as olefin hydrogenation saturation, hydroisomerization, and catalytic cracking, will affect the desulfurization performance of the adsorbent in the reaction process, 31–33 and these side reactions will also be affected by reaction temperature and adsorbent activity. To investigate the desulfurization performance, the influence of these side reactions on the desulfurization performance of the adsorbent cannot be ignored.…”

Recent global events have led to the cost of platinum group metals (PGMs) reaching unprecedented heights. Many chemical companies are therefore starting to seriously consider and evaluate if, and where, they can substitute PGMs for non-PGMs in their catalytic processes. This review covers recent large-scale applications of non-PGM catalysts in the modern pharmaceutical industry. By highlighting these selected successful examples of non-PGM-catalyzed processes from the literature, we hope to emphasize the enormous potential of non-PGM catalysis and inspire further development within this field to enable this technology to progress towards manufacturing processes. We also present some historical context and review the perceived advantages and challenges of implementing non-PGM catalysts in the pharmaceutical manufacturing environment.
