摘要: Abstract The concentration of acidic hydroxyl groups, sorptive properties, and catalytic activity for cumene cracking toluene disproportionation were compared different stabilized catalysts, viz., “deep-bed” “ultrastable,” aluminum-deficient Y zeolites. It was concluded that only a fraction the hydroxyls could be catalytically active. reaction requires groups with higher acidity. Several structural properties have favorable effect on nature active sites both reactions.
