“…[25,26] In the hydrocracking of nhexadecane, the comparison of mesoporous FAU-Y with a set of aluminated mesoporous silicas [27] showed that the catalytic activity relates linearly to the number of strong BrØnsted acid sites, while selectivity, more precisely the yield in isomerization products, scaled directly with the mesopore volume of the catalyst. The number of strong BrØnsted acid sites can be adjusted by tuning the synthesis conditions [28,29] and appeared to be correlated to the micropore volume of the mesoporous zeolite. [10] The influence of the micro-/and mesopore surface areas in mesoporous zeolites in catalysis and adsorption is seldom discussed.…”

“…It has already been shown that especially hierarchical mesoporous zeolites are very promising catalysts in hydrocracking of hexadecane and with increased mesoporosity the product distribution in hydrocracking of hexadecane can be increased [3]. Hydrocracking processes are performed industrially in fixed bed reactors [4]. A current trend in fine chemicals industry is to switch from batch to continuous operation.…”

“…44,45 Previous studies with NiMoS on modi-ed or mesoporous USY have been explored for hydrogenation, hydrocracking, and ring opening reactions for heavy vacuum gas oil (HVGO)/light cycle oil (LCO). [46][47][48][49] The morphologies of the MoS 2 phase, as well as the vicinity and the strength of the acid sites are vital for such upgrading. Hydrogen spillover and better metal (Pd) dispersion on 20% HY (Si/Al ¼ 2.3) and Al 2 O 3 were reported to be benecial for high phenol HDO.…”
