Abstract
A new synthetic porous crystalline material, designated EMM-1, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making EMM-1 in the presence of HF using various organic nitrogen compounds as directing agents. Aluminum-containing EMM-1 can be produced either by inclusion of Al in the synthesis, or by incorporation of B or Ga in the synthesis, followed by post treatment with aluminum nitrate or other sources of Al. EMM-1 is useful as an acid catalyst and as an adsorbent.
Claims10
A synthetic porous crystalline material comprising a framework of tetrahedral atoms bridged by oxygen atoms, the tetrahedral atom framework being defined by a unit cell with atomic coordinates in nanometers shown in Table 1, wherein each coordinate position may vary within ±0.05 nanometer.
A synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table 2 of the specification.
