摘要

1. A gallium-containing and/or indium-containing zeolite which a) has the following composition : SiO2 : (0.09 +- 0.07) [Al2 O3 + M2 O3 ] : (0.12 +- 0.010) [Na2 O + K2 O] : (0.12 +- 0.010) R2 O expressed as molar ratios of oxides, wherein R is choline and M is gallium and/or indium, and b) exhibits, in the X-ray diffraction diagram, the characteristic signals listed in Table 1 : Interlayer spacing Relative intensity d[A] I/I0 11.5 +- 0.2 very strong 9.2 +- 0.2 weak 7.6 +- 0.2 weak to medium 6.6 +- 0.1 medium to strong 5.7 +- 0.1 weak to medium 5.35 +- 0.1 weak 4.98 +- 0.1 weak 4.56 +- 0.1 medium to strong 4.32 +- 0.1 strong 4.16 +- 0.1 weak 3.81 +- 0.1 strong to very strong 3.75 +- 0.1 strong to very strong 3.59 +- 0.1 strong to very strong 3.30 +- 0.1 medium 3.15 +- 0.1 medium 2.92 +- 0.1 weak 2.86 +- 0.1 strong to very strong 2.80 +- 0.1 weak 2.67 +- 0.1 weak 2.49 +- 0.1 weak In the above table, I0 denotes the intensity of the strongest signal.
