Crystalline aluminophosphates and related compounds having in the as-synthesized dried form the chemical composition expressed as

Crystalline aluminophosphates and related compounds

A process for the preparation of alkenes by contacting a feed containing one or more C.sub.2 -C.sub.10 alkanes at an elevated temperature with a catalyst containing 1-15% w vanadia, calculated as divanadium pentoxide relative to the weight of the catalyst, on a refractory support, where the feed is contacted with the catalyst at a temperature of 600.degree. C. or above during less than 4 seconds.

Process for the preparation of alkenes

A process for the removal of hydrogen from a mixture of hydrogen and one or more organic compounds, which comprises contacting the mixture with a molecular sieve containing a reducible metal cation, said molecular sieve being selectively permeable to hydrogen.
