Abstract
The present invention relates to MFI-type silicalite-1 zeolite crystals that are individual crystals having a three-dimensional morphology in which the cross section parallel to the longest length corresponds in shape to a straight-line-truncated disk (or ellipse). The invention also relates to the process for synthesizing said crystals and to the use thereof as zeolitic adsorbents.
Claims14
MFI-type silicalite-1 zeolite crystals:
- in which the number-average diameter measured by scanning electron microscopy is between 0.2 μm and 7 μm,
- in which the width/length ratio measured by examination with a scanning electron microscope is between 0.1 and 1 and the thickness/length ratio measured by examination with a scanning electron microscope is between 0.05 and 0.5, and
- in which the monomodal particle size distribution determined by examination with a scanning electron microscope has a peak width 2σ of equal to or less than 5.
