	<span lang=\"EN-US\" style=\"font-family:Verdana;\">Methylation of toluene over ZSM-5
zeolites modified by the introduction of Sr of 2.5%, 5%, and 10% by weight was
studied. Experiments were performed in a fixed bed</span><span lang=\"EN-US\" style=\"font-family:Verdana;\"> under the conditions
of </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">reaction temperatures

Sr/ZSM-5 catalyst has the highest selectivity for p-xylene production. Nevertheless,
the catalyst 2.5% Sr/ZSM-5 has the highest selectivity for m-xylene. The two
catalysts 2.5% and 5% Sr/ZSM-5 give nearly the same selectivity for the three
xylene isomers at all conversions obtained at the reaction conditions under
study.</span>
