Reaction of C-1-C-2 hydrocarbon conversion on decationated HNaZSM-5 at
50-400 degrees C under nonoxidative and oxidative conditions is descr
ibed. Experimental data which show the influence of population density
of active surface centres on the course of the reaction are presented
. Possible cooperative action of isolated acid centres and participati
on of radical intermediates in oxidative conversion are discussed. (C)
