• metathesis catalysts. For example, by supporting MoO3 on MCM-22(28) in Na+ form (6 wt % of Mo) we obtained material providing only 0.5% 1-octene conversion in 19 h (1-octene/Mo = 320, t = 40 °C). Therefore, we converted Na+ forms to NH4+ forms, which were used for supporting Mo compounds by thermal spreading
