In this work

monolithic SSZ-13 zeolite was synthesized using dry-gel conversion method. The influences of the gel composition and crystallization conditions on the crystallization of SSZ-13 zeolite were investigated. The as-synthesized product was characterized by X-ray diffraction (XRD)

X-ray fluorescence (XRF)

thermo gravimetric-differential thermal analysis (TG-DTA

scanning electron microscope(SEM)

NH3 temperature-programmed desorption(NH3-TPD

Nuclear Magnetic Resonance (NMR). The roles of N

N

N-trimethyl-1-adamantanammonium (TMADa+) and choline chloridein crystallization reaction were discussed. According to the result

the monolithic SSZ-13 zeolite has typical accumulated mesopores

larger surface area and better thermal stability in air. The results in FT-IR and NMR spectra show that choline chloride could act as a secondary structure-directing agent and fill in the pores of zeolite

which significantly reduced the amount of TMADa+. It was confirmed that Choline Chloride favors accelerating zeolite nucleation

shortening the crystallization time

and improving crystallinity of the as-synthesized product.
