Disproportioning of toluene on Pd-H Mordenite catalyst

V.Sh. Aghayev - Institute for Catalysis and Inorganic Chemistry

Synthetic mordenite ceolite was decationized and dealuminated with 2N hydro-chloride acid, calcinated in the temperature range of 500−600 oC. Obtained samples of H-mordenite and initial Na-mordenite have been analyzed on the X-ray phase difractometer and according to the X-ray patterns it was defined that the silica module of elasticity of H-mordenite comprised 17, and the crystallinity reduced for 2-3 %. Furthermore, obtained sample of ceolite catalyst of H-mordenite was modified with Pd+2 ions up to 0.3, 0.5 and 0.8 % by the mass. Catalyst activity of sythesized H-mordenites and metall-ceolite catalysts containing various amount of Pd+2 metal cations was studied in the reaction of disproportioned toluene to the benzole and xylol in the temperature 300−380 °C, H2: CH = 3: 1 mole in the rate of 3.1 h-1. It was defined that the catalyst of 0.5 % Pd-H-mordenite (SiO2: Al2O3 = 17) shows better activity for this reaction.
