“…However, many current non-noble metal catalysts have low catalytic activity in the isomerization of n-alkanes compared with noble metal catalysts [17][18][19]. Fortunately, our recent study proved that amorphous NiP/Hβ catalysts exhibit a good catalytic function in the isomerization of light alkanes.…”

To study how calcination temperature influences the structural properties and catalytic performance of a novel amorphous NiP/Hβ catalyst, amorphous NiP/Hβ catalysts calcined at different temperatures were prepared for n-hexane isomerization. The optimum calcination temperature was determined, and the effect of calcination temperature on the structural properties of the catalysts was investigated using different characterization methods, such as XRD, TPD and so on. It was found that the optimum calcination temperature was 200 °C. Simultaneously, the amorphous NiP/Hβ catalyst showed good application potential as a non-noble metal catalyst. Calcination temperatures from 100 to 400 °C had almost no effect on pore properties. Meanwhile, the acid properties of the amorphous NiP/Hβ catalyst were affected very little by calcination temperature. By increasing calcination temperature, the dispersion state of amorphous NiP became worse at 300 °C, and then the structure of NiP changed from an amorphous structure into a crystalline structure at 400 °C. In addition, the catalyst became more difficult to reduce with the increase in calcination temperature. Combined with the results of n-hexane isomerization catalyzed by different samples, the mechanism by which calcination temperature affects n-hexane isomerization over catalyst was revealed. It was shown that for the amorphous NiP/Hβ catalyst, calcination temperature influences the catalytic performance mainly by affecting the dispersion degree and structure of active components.

“…[55][56][57][58][59] Goguet and co-workers observed the formation of an oxycarbidic phase on the MoO 3 catalyst, but indicated that lattice carbon did not inuence isomerisation activity. 60 Nonetheless, both phases (i.e., MoO x C y H z or MoO 3Àx ) contain lower valence Mo 5+ and Mo 4+ states. 50,56 Control experiments show that MoO 2 and MoS 2 (i.e., Mo 4+ state) are completely inactive for the HDO of phenolic compounds.…”

We have investigated the catalytic activity of W 2 C/HZSM-5 and Mo 2 C/ HZSM-5 for conversion of n-heptane to LPG and aromatic products. The results show that the catalytic activity of the metallic carbides increases markedly in the presence of ZSM-5. For pure carbides, the main cracking products are methane and ethane as a result of the cleavage of the C-C bond at the end of the hydrocarbon chain. In contrast, the zeolitic catalysts produce LPG (propane, i-butane, and n-butane) through the cleavage of C-C bond in the medial bonds. It is observed that the metallic carbides play a key role in producing the aromatics, concerning the formation of olefin species and cyclization of them in the channels of zeolite.
