New decationised, dealuminised and stabilised L zeolite |
摘要 |
The present invention relates to a new decationised, dealuminised and stabilised zeolite having a structure of L type characterised especially by: an overall SiO2/Al2O3 molar ratio greater than or equal to 8; a potassium content less than 2.9 % by weight; @ and @ parameters of the unit cell respectively less than 1.836 nm and 0.754 nm; a nitrogen adsorption capacity at 77 K for a P/Ps partial pressure = 0.19 greater than 11 % by weight; a benzene adsorption capacity at 30 DEG C for a P/Ps partial pressure of 0.25 greater than 8.5 % by weight; a mesopore network whose radii, measured by nitrogen adsorption/desorption at 77 K using the BJH method, are between 0.8 nm and 20 nm.
