Improved zeolites and molecular sieves and the use thereof

Original document(17 pages) 中文版

An improved zeolite having a high number of strong acid sites wherein said zeolite has an AAI of at least (1.0). In a preferred embodiment, such zeolite is produced by controlling conditions after production of the crystalline structure such that loss of tetrahedral aluminium is minimized to thereby provide a zeolite with the above defined AAI.
