Crystalline beta zeolite molecular sieve was synthesized by the hydrothermal crystallization method with associated SiO2/Al2O3 molar ratio of 28.5. The performance of the micro-mesoporous beta zeolite sample was investigated between 300 and 450°C showed the TOFMeOH of 741.9 h-1 at 300°C for methanol dehydration reaction. Dimethyl ether (DME) was observed as the predominant product at all reaction temperatures, with a maximum selectivity of 47.9% at 300°C. At increased reaction temperatures, the beta zeolite showed enhanced strong acid site fraction, promoting higher hydrocarbon formation following the olefin-based cycle. Aromatic-based cycle was also enhanced with temperature and promoted the production of hexamethyl benzene. Spent beta zeolite showed changes in crystallinity, porosity, and acidity while comparing the fresh sample. Amorphous carbon deposition occurred on beta zeolite during activity tests. The regeneration cycle test showed stable activity of regenerated beta zeolite for 280 h time-on-stream.
The dataset was collected by several characterization and activity test experiments for preparation of the submitted manuscript. All the data has been processed and analyzed by the authors of the manuscript. The shared data is in .xlx, .txt and .csv formats.
