Ni nanocatalysts supported on MIL-53(Al) for DCPD hydrogenation

Abstract

Supported Ni catalyst with rich mesoporous structure and uniform distribution of Ni shows high catalytic activity performance toward the hydrogenation of DCPD.

Hydrogenation of Dicyclopentadiene over Stable SiO2@Ni/C Catalysts under Mild Conditions

“…Most of the reported catalysts toward DCPD hydrogenation still undergo inefficient batch reactions in the reactor, which is not conducive to large-scale applications. , To explore the potential of the SiO 2 @Ni/C catalyst for industrial applications, the continuous hydrogenation of DCPD was tested on a fixed bed. The turnover frequency (TOF) was calculated according to this formula: TOF = (the molar amount of DCPD converted per h)/(molar amount of loaded nickel determined by ICP).…”

“…The current commercial catalyst for DCPD hydrogenation is Raney nickel. However, the flammability and tedicate post-treatment of Raney nickel limit its large-scale application . Supported metal catalysts have received extensive attention.…”

“…Recently, metal–organic frameworks (MOFs) with large specific surface areas and rich pore structures have been used as a precursor to prepare highly dispersed Ni catalysts . The Ni nanocatalyst supported on MIL-53 prepared by Li et al shows >98% THDCPD selectivity and >98% DCPD conversion at a low temperature of 60 °C . However, the stability of the catalyst is poor.…”

Defect Engineering in Ce-Based Metal–Organic Frameworks toward Enhanced Catalytic Performance for Hydrogenation of Dicyclopentadiene

“…The hydrogenation of dicyclopentadiene (DCPD) to tetrahydrodicyclopentadiene (THDCPD) is a crucial reaction step to obtain JP-10. Raney Ni is currently the predominant hydrogenation catalyst utilized in industrial production, demonstrating remarkable efficiency in converting DCPD to THDCPD with yields surpassing 96%. − Nevertheless, this catalyst is susceptible to deactivation and lacks the ability to be recycled for multiple applications. Furthermore, alternative catalytic materials predominantly consist of noble metals, − posing cost-related challenges.…”
