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.
