چکیده

A study was conducted to evaluate the effect of reaction pressure on the toluene disproportionation reaction using ZSM-5 zeolite based catalyst impregnated with molybdenum. Results showed that there is a marked difference in toluene conversion and xylenes selectivity using nitrogen and hydrogen carrier gases and the reaction pressure. Toluene conversion under nitrogen pressure was higher than under hydrogen pressure. Toluene conversion was found to increase with increasing in pressure and temperature for both carrier gases. Deactivation of the catalysts was observed faster and greater in nitrogen as compared to hydrogen carrier gas as indicated by higher amount of coke formation.

Structure of toluene6.4-ZSM-5 and the toluene disproportionation reaction on ZSM-5.

The structure of a high-loading complex of ZSM-5 with 6.4 toluene molecules per unit cell has been determined by single-crystal X-ray diffraction. At least three kinds of toluene molecules were identified in the unit cell. Two disordered toluene molecules were located at the intersection of the straight and sinusoidal channels, the third in the sinusoidal channel. One (TOL1) of the two toluene ...
