Patent ID: 7737316

Claim:
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 x Al y P z )O 2 wherein wherein R represents at least one templating agent, preferably an organic templating agent; m is the number of moles of R per mole of (Si x Al y P z )O 2 ; and m is greater than 0.1 to 1, x is greater than 0 to about 0.25, y is in the range of from 0.4 to 0.5, and z is in the range of from 0.25 to 0.5; wherein the processable molecular sieve crystalline product forms a molecular sieve slurry having a viscosity of less than about 10,000 cps; further comprising adjusting the determined amount of flocculant effective to recover the molecular sieve crystalline product by a correction factor of from about 0.75 to about 0.98; (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).
