New crystalline solid zeolite for use as adsorbent or catalyst, shows a characteristic X-ray diffraction pattern and is based on silicon and optionally other elements

摘要

A crystalline solid (IZM-1) with an X-ray diffraction pattern showing very strong lines at 2 theta = 7.60 and 21.22 [deg] , a strong line at 2 theta = 22.96 [deg] and numerous other lines (very weak to average), and with a mixed oxide composition containing tetravalent element(s), optionally trivalent element(s) and optionally alkali and/or alkaline earth metal(s). A crystalline solid (IZM-1) with an X-ray diffraction pattern showing very strong lines at 2 theta = 7.60 and 21.22 [deg] , a strong line at 2 theta = 22.96 [deg] , an average-weak line at 2 theta = 8.78 [deg] , weak lines at 2 theta = 15.24, 21.68 and 23.26 [deg] , and very weak lines at 10.74, 11.43, 12.45, 14.60, 16.93, 17.62, 18.15, 18.73, 19.15, 20.76, 22.58, 24.52, 25.03, 25.44, 25.82, 26.24, 26.56, 29.14, 29.45, 30.79, 31.45, 31.72, 33.04, 33.60, 34.22, 36.28, 37.14 and 38.50 [deg] . The composition of this material, expressed on an anhydrous basis in terms of moles of oxides, is XO 2 : aY 2O 3 : bM 2 / nO, in which X : tetravalent element(s); Y : trivalent element(s); M : alkali or alkaline earth metal; n : valency of M; a : 0-0.02; b : 0-1 . An independent claim is also included for a method for the preparation of IZM-1 by mixing, in an aqueous medium, source(s) of oxide(s) XO 2, possibly source(s) of oxide(s) Y 2O 3, possibly source(s) of alkali and/or alkaline earth metal(s), possibly source(s) of hydroxide ions and at least two different organic species (R) and (S), followed by hydrothermal treatment until the formation of IZM-1, followed by filtration, washing, drying and calcination.
