2. 1. Molecular sieve macrostructures prepared by resin templating

   Author : Lubomira Tosheva; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Abstract : A novel template-based method for the preparation of molecular sieve macrostructures was developed. Silicalite-1, ZSM-5 and zeolite beta spheres were prepared by the method. The procedure was also used to produce amorphous silica macrostructures. Anion exchange resin beads were employed as macrotemplates to host the guest silica materials. READ MORE

4. 2. Structured molecular sieves : synthesis, modification and characterization

   Author : Valeri Naydenov; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Abstract : The work presented concerns synthesis of structured molecular sieves. The preparation procedure is based on the use of ion exchange resins as macrotemplates. Macroporous cation or anion exchange resin types were used depending on the molecular sieve type to be synthesized. READ MORE
