Economic Synthesis of SSZ-13 Catalyst Using Waste Mother Liquid for the Methanol-to-Olefins Reaction

Rapid synthesis of hierarchical SSZ-13 zeolite microspheres via a fluoride-assisted in situ growth route using aluminum isopropoxide as aluminum source

“…As reported in our previous work, 18 conventional microporous SSZ-13 crystals were synthesized from the starting gel with a molar composition of Al 2 O 3 : 40 SiO 2 : 4 TMAdaOH: 4 Na 2 O: 1760H 2 O under conventional hydrothermal conditions at 160 °C for 48–144 h. Aluminum isopropoxide and aluminum nitrate were used as aluminum sources, respectively. The synthesis process for these zeolite crystals was similar to that of the system for synthesizing hierarchical SSZ-13 crystals without using HF.…”
