    摘要: The invention is directed to a method for preparing microporous aluminophosphate or silicoaluminophosphate molecular sieves having the CHA framework type, the process comprising the steps of a) forming a reaction mixture comprising a source of aluminum, a source of phosphorus, optionally a source of silicon, at least one source of fluoride ions and at least one template containing one or more N,N-dimethylamino moieties, b) inducing crystallization of aluminophosphate and/or silicoaluminophosphate molecular sieve from the reaction mixture; c) recovering aluminophosphate and/or silicoaluminophosphate molecular sieve from the reaction mixture. The invention also relates to the molecular sieves obtained by this method and to molecular sieve catalyst compositions containing these molecular sieves.

    摘要: In a process for selectively separating 1-butene from a C4 feed stream comprising at least 1-butene, cis-2-butene and trans-2-butene, the feed stream is passed through a first bed of an adsorbent comprising a crystalline microporous material to form a substantially trans-2-butene-free effluent stream. Then, the substantially trans-2-butene-free effluent stream is passed through a second bed of an adsorbent comprising a crystalline microporous material to form a substantially 1-butene-free effluent stream, whereby the 1-butene is separated from the feed stream. The adsorbed 1-butene is then typically desorbed from the second adsorbent bed either by lowering the pressure or raising the temperature of the bed.
