摘要：

The isomerization reaction of m-xylene made it possible to establish high para-selectivity and isomerizing selectivity of polymetallic catalyst based on high-silica zeolites such as ultrasil modified lanthanum, germanium and platinum due to the creation of optimal combination of metal and acid sites. Selectivity and isomerization rate made up 26.8-30.6 wt% and 94.8-97.8% respectively on the 0.5% Pt 0.25% Ge 0,68La.US polymetallic catalyst at the 350-400 degrees C temperature range.
