Abstract

SSZ-13 molecular sieve is prepared by the traditional hydrothermal method with silica sol, aluminium sulphate, sodium
hydroxide and deionized water as raw material, and N, N, N-trimethyl-l-adamant ammonium hydroxide as a template. It
is investigated in terms of the influencing factors and optimal reaction conditions, and characterized with XRD, BET
specific surface area meter and FT-IR. The experimental results indicate that the obtained SSZ-13 molecular sieve has
advantages of shorter reaction time, higher crystallinity and larger specific surface area. The reaction time is further
shortened to 2 days by introducing crystal seed or accelerant, which lowers the total preparation cost of SSZ-13 and
makes its industrialization highly feasible.
