| Sumario: | Samples of SAPO-11 were synthesized by hydrothermal crystallization, with the objective of investigating the influence of the method of synthesis on the properties such as crystallinity, morphology, and catalytic activity. Solid products were analyzed by X-ray diffraction, scanning electronic microscopy and plasma emission spectroscopy. Catalytic evaluation of the samples in ethylbenzene disproportionation was realized using a continuous flow fixed bed reactor connected on-line with a gas cromatograph. The results with regard to percentual conversion of ethylbenzene and para-selectivity are given |
