“…Friedel–Crafts (FC) alkylation can produce high-value diphenylmethane and its derivatives in petrochemical and fine chemicals. − Typically, these reactions are catalyzed by homogeneous catalysts such as BF 3 , BeCl 2 , ZnCl 2 , FeCl 3 , AlCl 3 , TiCl 4 , SnCl 4, SbCl 5 , and H 2 SO 4. ,, However, the inherent disadvantage of these homogeneous catalysts is that they are toxic and difficult to separate and regenerate.…”

We reported a perfect strategy for the fabrication of Cu-encapsulated hierarchical MEL zeolites by a simple post-desilication−recrystallization strategy. The Cuencapsulated hierarchical MEL zeolites exhibited extraordinary selectivity in the liquid alkylation reaction of mesitylene and benzyl alcohol compared with hierarchical MEL zeolites, indicating that the additional Cu species located in the matrix of MEL zeolites can effectively inhibit self-etherification of benzyl alcohol. In addition, the selectivity of 2-benzyl-1,3,5trimethylbenzene for the Cu-containing hierarchical MEL zeolites was in the order of

“…As is shown in Figure , all the samples exhibit the typical type IV isotherms, which is closely related to capillary condensation in mesopores . In addition, it seems that the hysteresis loops of the series samples are suggested to be the H3 type, indicating the existence of a slit-shaped structure . In addition, it should be noted that these two samples possess abundant micropore structures, as is evidenced by the micropore filling phenomena .…”

In this study, a series of Mn-modified HZSM-5 samples were synthesized using the solid-state ion-exchange method, and the effects of the manganese loading amount, calcination temperature, reaction temperature, and gas components on mercury removal efficiency were systematically explored. Given that the mass ratio of HZSM-5 to KMnO 4 and the calcination and reaction temperatures were set to 10:2.6 and 400 and 150 °C, Hg 0 removal efficiency could reach a peak value of 96.4% when exposed to the flue gas containing 5% O 2 and N 2 as the balance. Among the various gas components, O 2 and NO showed a positive impact on Hg 0 removal; Hg 0 removal efficiency could even reach ca. 100% when O 2 and NO were simultaneously introduced. In contrast, the introduction of SO 2 led to a decline of Hg 0 removal efficiency by ca. 16%. In addition, Hg 0 removal efficiency could still retain ca. 92% of that for the fresh sample after six regeneration and reuse cycles, which is indicative of a satisfactory stability and renewability. Finally, Mars–Maessen mechanisms dominated in the mercury chemical adsorption process.
