The molecular sieve is a class of nanoparticles with a special purpose,has a wide range of applications in multiple areas of the catalysts,ion exchangers,adsorbents,and new functional materials.Nano-scale NaY zeolite as a catalyst support or catalyst active component was often used in the residueand isomerization,hydrocracking and catalytic cracking refining process of heavy oil,showing a superior performance than the conventional size of NaY zeolite,and thus been more and more attention.At the same time,nano-NaY zeolite adsorption material,ceramic membrane materials and environmental protection have a new application prospects.Therefore,in recent years,nano-scale NaY zeolite as a new chemical material grows rapidly,which is becoming one of the hot research topics.It was based on the comprehensive analysis of domestic and foreign relevant template of molecular sieve synthesis influence of a large number of literature,the study had examined the effects of agent oriented silicon aluminum ratio,molecular sieve of the time and temperature of crystallization,template selection and dosage and other factors on the synthesis of NaY molecular sieve,and the optimum synthesis conditions.The synthesized NaY molecular sieves were characterized by SEM,XRD and BET,and the results showed that the molecular sieve was high Si / Al ratio.The process of the synthesis of NaY molecular sieve was carried out at room temperature,with mild reaction conditions and easy to control.The synthesis of NaY molecular sieve as hard template and sucrose as a carbon source successful prepared with rules of pore size distribution of porous carbon materials,discusses the NaY molecular sieve with concentrated sulfuric acid ratio,carbonization temperature,carbonization time factors on the synthesis of porous carbon effect.
