2-butenes was observed at room temperature. The SbF 5 complex is shown to polarize coadsorbed acetone to the same degree as magic acid. The stability of the metal halide complexes is further characterized with adsorption and reaction of propene and ethene to form oligomers. The aromatization was performed in a micro-reactor at 773 K and at atmospheric pressure. The addition of germanium on H-ZSM5 increases the activity for propane transformation but decreases the selectivity toward aromatic compounds.
Results show that both the total and strong acidity decrease with the addition of germanium.
It was shown that up to a sulfidation temperature of 573 K small highly active Co sulfide clusters were formed in the supercages. Sulfidation above 573 K led to decomposition of these Co sulfide particles by a protolysis reaction resulting in the formation of H 2 S and a blue colored Co compound having almost no HDS activity. Their activity depends largely on the experimental conditions and is restricted by the strong adsorption of organic species, either acetic acid or acetyltetralin formed in the reaction. Y. Yue Y. Sun Z. Gao MoO 3 and NiO were supported on KIT-1, a new disordered mesoporous molecular sieve. MoO 3 is homogeneously dispersed as a monolayer on the support, whereas NiO tends to form small crystallites in the mesoporous channels.
