Аннотация: The influence of the SiO2/Al2O3 ratio and decationation degree on the process of adsorption of ethylene-temperature-programmed decomposition of the oligomers on the surface of NaHZSM-5, HM, HY was studied. It was found that the specific rate of ethylene adsorption (formation of oligomers) did not depend upon decationation degree whПоказать полностьюereas the activity in reaction of hydrogen redistribution (formation of paraffins) decreased with increase of sodium content or SiO2/Al2O3 ratio. A similar behavior was observed for HY and phosphoric acid in conversion of ethylene. It was proposed that it is the multi-point adsorption centres which are responsible for the hydrogen transfer reactions while oligomerization takes place on isolated acid centres.
