The characteristics of ZSM-11

 ZSM-11 (also known as MEL) contains a two dimensional 10-ring pore structure. Both sets of pores are straight.ZSM-11 zeolite is a high silica ZSM series, a member of the tetragonal, belonging to Pentasil zeolite, ten dollars from the oval ring made ​​of three-dimensional straight channels intersect.ZSM-11 zeolite has a very unique crystal structure, the crystal structure of alumina is high, the crystal surface with a clear role and strong hydrophobic surface acidity, it is important to good shape-selective adsorbent and catalyst. For toluene - methanol alkylation, xylene isomerization and toluene disproportionation reaction
Listed below are a number of different zeolite structures in JPEG, virtual reality images (VRML), and SolidWorks formats.
 You can view the JPEG's easily with any browser, but the VRML files require a pluggin (see below) and the SolidWorks files would generally be downloaded and opened using SolidWorks software. Many other types of 3D modelling software support SolidWorks images as well. The VRML and SolidWorks files are 3D, while the JPEG's are 2D projections. These are stacked tetrahedral images which are constructed by drawing tetrahedra around the tetrahedrally coordinated Si or Al T-atoms, then adding spheres to depict the oxygen atoms which connect the Si and/or Al atoms. The actual diameter of the oxygen atoms is larger than depicted in these diagrams, but if they were drawn to actual dimensions, they would completely engulf the teterahedra, so we would lose the tetrahedral representation of the zeolites.
