Synthesis Optimization of SSZ-13 Zeolite Membranes by Dual Templates for N2/NO2 Separation
文献摘要：
High-silica SSZ-13 zeolite membranes are promising in industrial separations of light gases and continuous membranes are highly demanded for better separation performances.Herein,pure-phase,continuous and thin SSZ-13 zeolite membranes were synthesized using dual templates of N,N,N-trimethtyl-1-adamantammonium hydroxide(TMAdaOH) and tetraethylammonium hydroxide(TEAOH).Systematical investigations of TMAdaOH/TEAOH ratios and their concentrations show that TMAdaOH acts as the main structure-directing agent in the formation of the SSZ-13 zeolite.TMAdaOH cooperatively plays with TEAOH in promoting the SSZ-13 crystal intergrowth to form a continuous polycrystalline membrane.Additionally,appropriate introduction of TEAOH is able to adjust the membrane thickness to the crystal-comparable size of ca.2.0 μm.The SSZ-13 membranes are further applied for N2/NO2 separation,which is firstly reported on zeolite membranes.The gas permeation results show that the SSZ-13 membrane synthesized by the dual-template approach exhibits selective separation of N2 over NO2 with N2/NO2 separation factor of 7.6 and N2 permeance of 1.66×10-8 mol·m-2·s-1·Pa-1.
