n-Hexane activation over zeolites: aromatic alkylation to 1-phenylhexane.

Terminal 1-phenylhexane was observed during alkylation of benzene with n-hexane over 10-membered ring zeolites at moderate temperature, whereas it was not observed when 1-hexene was the reactant.

In situ XAS and XRPD parametric rietveld refinement to understand dealumination of Y zeolite catalyst.

Dealumination of NH(4)-Y zeolite during steaming to 873 K was investigated with in situ, time-dependent, synchrotron radiation XRPD and in situ Al K-edge XAS. Water desorption is complete at 450 K, and ammonium decomposition occurs between 500 and 550 K. Only a small fraction of Al(3+) species (5%) leaves the framework during heating from 710 to 873 K; these species occupy site I' inside the sodalite cage.
