Effect of nitric acid peptizator on the performance of a MCM-22 zeolite catalyst;

Density functional theory was employed to study the geometric and electronic structure of molybdenum carbide loaded on MCM-22 zeolite and predict the mechanism for CH4 activation.

Effect of PEG2000 on structural characteristics and catalytic performances of MCM-22 molecular sieve;

Coke-deposition on external surface of MCM-22 molecular sieve catalyst,formed during isomerization of 1 -butene to isobutene, was characterized by means of NH3 -TPD, TG-DTA, GC-MS, elementary analysis, N2 adsorption and SEM.

Aromatization of butene in liquefied petroleum gas on MCM-22 molecular sieve catalysts with different silica to alumina ratios(n(SiO_2):n(Al_2O_3))were carried out in a continuous fixed bed reactor.

In this thesis, the acidity and the active center of MCM-22 zeolite wereinvestigated by theoretical calculation.
