Abstract:
1. A process for producing one or more olefin(s), the process comprising: (a) preparing a molecular sieve product mixture, the molecular sieve product mixture comprising the molecular sieve crystalline product, and a binder; (b) separating the molecular sieve product mixture into a plurality of samples; (c) mixing at least two of the plurality of samples with a quantity of flocculant to produce a plurality of flocculated samples, wherein at least two of the plurality of flocculated samples have a different ratio of flocculant to molecular sieve crystalline product mixture; (d) measuring the viscosity of at least two of the plurality of flocculated samples having a different ratio of flocculant to molecular sieve crystalline product mixture; (e) establishing a relationship between the quantity of flocculant and the viscosity measurements; and (f) determining from the relationship the amount of flocculant effective to recover the molecular sieve crystalline product resulting in a processable molecular sieve crystalline product having the general formula mR:(Si (g) formulating the crystalline product into a molecular sieve catalyst; (h) introducing a feedstock comprising one or more oxygenates to a reactor system in the presence of the molecular sieve catalyst; (i) withdrawing from the reactor system an effluent stream; and (j) passing the effluent stream through a recovery system recovering the one or more olefin(s).
