Microwave synthesis of zeolites: 1. Reactor engineering

Article Abstract:

The synthesis of silicalite employing two geometries in an oven with 2045-GHz microwaves is studied. It was observed that the distribution of microwave energies within the reactors from simulation differed, and the morphologies and yields of the resultant zeolite also differed. Larger uniform silicalite crystals were formed in the larger reactor in which the variation in microwave energy distribution was greater.

Dehydrated and Cs(super +) - exchanged MFI zeolites: Location and population of Cs(super +) from in sity diffraction data as a function of temperature and degree of exchange

Article Abstract:

The first instance where the cesium cations in dehydrated and Cs-exchanged MFI material are unambiguously located over a wide range of Cs exchange. The correlations describing the evolution of the Cs populations at room temperature as a function of total Cs/uc contents clearly establish that the mechanism of Cs incorporation into the MFI framework channel is unique.

IR studies of the activation of C=C bond in alkenes by Cu(super +) ions in zeolites

Article Abstract:

IR studies indicate that Cu(super +) ions in zeolites CuX, CuY, and CuZSM-5 could activate C=C bonds in alkenes (ethene, propene,. but 1-ene, and cis-but-2-ene). The activation of alkene activation by Cu(super +) in zeolites is similar as in NO activation.
