The catalytic conversion of hydrocarbon feedstocks is affected under effective conversion process conditions in the presence of silicoaluminophosphate-based catalyst compositions.

Hydrocarbon conversions using catalysts silicoaluminophosphates

Crystalline molecular sieves having three-dimensional microporous framework structures of MO.sub.2.sup.n, AlO.sub.2, and PO.sub.2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula:

Molecular sieve compositions

Crystalline molecular sieves having three-dimensional microporous framework structures of FeO.sub.2, TiO.sub.2, AlO.sub.2, and PO.sub.2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula:

Iron-titanium-aluminum-phosphorus-oxide molecular sieve compositions

Novel class of crystalline microporous ferroaluminophosphate compositions containing as lattice constituents in addition to AlO.sub.2 and PO.sub.2 structural units, ferric and/or ferrous iron in tetrahedral coordination with oxygen atoms. These compositions are prepared hydrothermally using organic templating agents and are suitably employed as catalysts or adsorbents.

Hydro-carbon conversion using ferroaluminophosphates

Crystalline ferroaluminophosphates

A novel class of crystalline microporous silicoaluminophosphates is synthesized by hydrothermal crystallization of silicoaluminophosphate gels containing a molecular structure-forming templating agent. The class comprises a number of distinct species, each with a unique crystal structure. The compositions exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as adsorbent or catalysts in chemical reactions such as hydrocarbon conversions.
