can be calculated ssz 102 is useful as an adsorbent for gas separations ssz 102 can also be used as a catalyst for converting oxygenates e g methanol to olefins and for making small amines ssz 102 can be used to reduce oxides of nitrogen in a gas streams such as automobile exhaust ssz 102 can also be used to as a cold start hydrocarbon trap in combustion engine pollution control systems ssz 102 is particularly useful for trapping c3 fragments ssz 102 can be used to separate gases for example it can be used to separate carbon dioxide from natural gas typically the molecular sieve is used as a component in a membrane that is used to separate the gases examples of such membranes are disclosed in u s pat no 6 508 860 the present disclosure comprises a process for catalytic conversion of a feedstock comprising one or more oxygenates comprising alcohols and ethers to a hydrocarbon product containing light olefins e g c 2 c 3 and or c 4 olefins the feedstock is contacted with ssz 102 at effective process conditions to produce light olefins the term u201c oxygenate u201d as used herein designates compounds such as alcohols ethers and carbonyl compounds e g aldehydes ketones carboxylic acids the oxygenate can contain from 1 to.
