“…However, reflections at 37.2°, 43.3°, and 62.9° corresponding to the (111), (200), and (220) planes of the NiO phase (JCPDS 04-0835) are perceived only in the PM-2.5% (2.5 wt% Ni) catalysts. 10,22,30 This result indicates that the Ni in IWI-2.5% (2.5 wt% Ni) and IE-2.5% (2.5 wt% Ni) samples shows good dispersibility in the carrier. Meanwhile, the uniform distribution of Ni can effectively avoid the deactivation of the catalyst due to the sintering effect, 31 thereby promoting the stability and reaction activity of the catalyst.…”

BACKGROUND: Isobutene oligomerization is a very promising reaction, and it has always been a research hotspot in the separation of mixed C4. A supported catalyst is a promising olefin oligomerization catalyst. In the work reported, a supported Fe 2 O 3 -Cl/⊎-zeolite molecular sieve catalyst was synthesized by changing the loading amount of various active components, and its catalytic effect on the selective oligomerization of isobutene was studied. The catalyst was characterized using various techniques. The experiments were carried out in a fixed bed reactor, and the effects of Fe loading, temperature and reaction space airspeed were studied. RESULTS:The catalyst has a good catalytic effect on this reaction with the load at 3%, the temperature at 70 °C, the pressure at 1 MPa and the reaction airspeed at 2 h −1 . CONCLUSIONS: The conversion of isobutene was above 90%, the selectivity of C8 was around 80% and the loss of n-butene was very small.

“…Currently, the Ni 2 P-based catalysts as an alternative to noble metal catalysts have been extensively studied for biomass HDO processes. 16 The Ni 2 P-based catalysts exhibit excellent HDO performance, which is attributed to the high d-electron density of the Ni 2 P phase, and a combination of structural and electronic influences of phosphorus atoms on the Ni metal sites favors oxygenate adsorption and C−O bond cleavage. 17 catalysts, partial deoxygenation of biomass derivatives is generally sufficient in the transfer hydrogenation process, but the overall deoxygenation efficiency is very low.…”

Catalytic transfer hydrogenation (CTH) is regarded as a promising technology for upgrading biomass to fuels and valuable chemicals in the presence of heterogeneous catalysts. In this work, three Ni 2 P-based catalysts, such as Ni 2 P@YSS with a yolk−shell structure, Ni 2 P@SiO 2 with a core−shell structure, and Ni 2 P/SiO 2 with a simple surface-loading structure, were prepared using different synthesis strategies, and were used in the CTH of vanillin in an ethanol environment. The Ni 2 P@YSS catalyst exhibited the highest conversion (85.6%) and a selectivity of 2-methoxy-4-methylphenol of 76.2% at 180 °C for 5 h among a series of Ni 2 P-based catalysts, which are closely related to the higher specific surface area (462 m 2 g −1 ), acidic site density (2.31 mmol g −1 ), and stronger metal−support interactions of the Ni 2 P@YSS catalyst. Besides, transition metals (Zr and La) were introduced to the Ni 2 P@YSS catalyst to increase the oxygen vacancy and improve the H dissociation ability, thereby enhancing the catalytic performance of the Ni 2 P-based catalysts.
