Abstract
- Abstract A rapid zeolite synthesis procedure was investigated using pulverized waste glass cullet via microwave radiation and compared with zeolites synthesized using convection heating. It was observed that constant temperature microwave synthesis method made zeolites more efficiently under superheating conditions with a maximum relative crystallinity of 60%. The maximum relative crystallinity of the synthesized zeolites was found to be similar when convection heating and constant temperature controlled microwave synthesis was used; however, the latter technique offerred a factor of 140 reduction in synthesis time. This rapid synthesis process is attractive to the industrial application due to its high-energy efficiency. Highlights • Rapid MW zeolite synthesis procedure was investigated using beverage WG cullet. • The MW zeolitic phases were compared with those synthesized by CH technique. • MWCT mode efficiently synthesized zeolites in superheating conditions with 60% RC. • The maximum RC of the zeolite synthesized by MWCT mode was close to the CH one. • MWCP mode synthesized poorly crystalline materials and was more energy consuming.
