Zusammenfassung:	Molecular sieve compositions are prepared by extracting aluminium and substituting chromium and/or tin for extracted aluminium to give molecular sieve products containing framework chromium and/or tin atoms. The process of preparing the chromium and/or tin-containing molecular sieves involves contacting a starting molecular sieve with a solution or slurry of at least one of a fluoro salt of chromium or a fluoro salt of tin under effective process conditions to provide for aluminium extraction and substitution of chromium and/or tin. Generally, the product molecular sieve has a unit molecular formula of (MwAlxSiy)02 where "M" is at least one of chromium or tin; and "w" "x" and "y" represent that mole fractions of "M", aluminium and silicon, respectively, present as framework tetrahedral oxide units, said mole fractions being such that they are within the triagonal area defined by points A, B, and C of Figure 13, having the following parameters: n
