“…There are few reports on the synthesis of SAPO-11 using different silicon sources. Nieminen et al [24] studied the effects of synthesis time and silicon sources on the synthesis of SAPO-11. They suggested that water glass favored tridymite phase instead of SAPO-11 phase.…”

“…The pyridine adsorption bands at ν̃ = 1455 and 1545 cm –1 are attributed to adsorbed pyridine molecules that have interacted with Lewis and Brønsted acid sites, respectively . The adsorption band at ν̃ = 1490 cm –1 indicates the multiple interactions of pyridine molecules with Lewis and Brønsted acid sites . The distributions of Brønsted and Lewis acid sites were calculated from the Py‐IR spectra with the Lambert–Beer equations and are listed in Table .…”

catalysts are prepared by both solvent-free and hydrothermal methods. SAPO-11 samples prepared by the solvent-free method have a higher density of acid sites compared with the samples obtained by the hydrothermal method. We performed 29 Si NMR spectroscopy to determine the acid properties of the samples, and most Si species exist in the SAPO region. The SAPO-11 materials were loaded with the noble metal Pt at a content of approximately 0.5 wt.-%, and the bifunctional catalysts were applied in the hydroisomerization of [a] Green Chemical Engineering Technology Research Center,

“…Further, a crystallization rate constant of *1 h -1 was shown for non-aqueous media synthesis at 200°C. Nieminen et al [28] studied the influence of synthesis time and silica source on the formation of SAPO-11. They showed that SAPO-11 formed after 24 h and the silica source played an important role in the phase formed.…”

Microwave Reaction Enhancement: The Rapid Synthesis of SAPO-11 Molecular Sieves

The effect of microwave and conventional heating methods on the nucleation and growth of SAPO-11 molecular sieve was investigated. Microwave synthesis enhances both the nucleation and growth of SAPO-11. The rate of heating primarily influences the nucleation time for both microwave and conventional heating. A more uniform morphology and narrower size distribution are formed using microwave heating compared to conventional. This suggests that rapid and even nucleation is the enhancement mechanism. Crystallization by conventional heating can be accelerated by immersion in the pre-heated fluid due to the faster heating rate and improved thermal conduction. Microwave synthesis of SAPO-11 occurs in minutes and, thus, significant energy savings can be realized compared to the hours required for conventional synthesis.
