Selective ethylene tetramerization with iron-based metal−organic framework MIL-100 to obtain C8 alkanes

Metal–Organic Gels Derived from Iron(III) and Pyridine Ligands: Morphology, Self‐Healing and Catalysis for Ethylene Selective Dimerization

“…As mentioned above,both Fe III MOGs had advantages of significant activity in catalyzing ethylene oligomerization. Thereinto, Fe-N gel with regular nanofiber structure enjoyed better ethylene dimerizationa ctivity to deliver C 4 olefins, whichd emonstrated that the assembly structure of MOG could distinctly affect its catalytic selectivity.I na ddition, under the same pres-sure and temperature, the oligomerization activity of Fe-N-20 exceeded the MIL-100(Fe) in our previouss tudy [8] and the Ni@(Fe)MIL-101 in literature, [5] indicating the Fe III MOGs might have potentiala pplications in the catalysis of ethylene dimerization.…”

“…[4] Among them, the metal-organicf ramework (MOF) materials derived from inexpensive metal elements with lowt oxicity such as Fe III , [5] Ni II , [6] Zr IV [7] have been emphatically investigated, and their selectivec atalytic capacities in ethylene dimerization have also been generally confirmed. However,t he fabrication procedures of these MOFs mostly involvei nh ydrothermal method [8] or solvothermalm ethod [9] conducted under long time andh igh-temperature, so these methods usually are rather energy-cost and time-consuming,w hich limit their practical application. Therefore, developingc atalysts for ethylene dimerization with high catalytic activity,f acile preparation and lower cost is of great significance to the ethylene industry,a nd it still remains ap aramountc hallenge.…”

Isomerization of 1-Butene to 2-Butene Catalyzed by Metal–Organic Frameworks

“…According to the literature reports, when MIL-100 (Fe) and MIL-100 (Cr) were evacuated from 150 to 250 °C, the diffraction peaks and specific surface areas gradually became strong. The higher evacuation temperature than 250 °C resulted in the decrease of PXRD peak intensity and specific surface areas.…”

Research progress of iron-based catalysts for selective oligomerization of ethylene

“…Combined with previous literature, it can be concluded that the application of co-catalysts in the whole catalytic process is mainly manifested in the following aspects: 90 (1) the co-catalyst acts on the iron metal center and produces an alkylation effect, thereby achieving the catalytic effect. 91,92 (2) The co-catalyst separates the alkylation groups on the metal center so that ethylene has more opportunities to contact with the metal active center, greatly increasing the reaction frequency of ethylene monomer and the metal active center. 93 (3) Part of the co-catalyst interacts with the center of the iron metal to produce anion-cation pairs, thereby enhancing the catalytic effect of the catalyst.…”

“…The researchers also found that the MOF system is reusable, inexpensive, and environmentally friendly. Han Yang et al 91 also investigated a new type of organometallic framework and supported iron-based catalysts on the carrier material to catalyze ethylene oligomerization. The results demonstrated that the main factors affecting the catalytic activity of MIL-100(Fe) supported catalyst system are as follows: (i) the surface area of the catalyst system; (ii) the content of the unsaturated site of Fe.…”
