Abstract:
1. A process for producing a bead composition comprising at least one of an amorphous and a crystalline molecular sieve component, the crystalline component having a three dimensional framework and a framework composition represented by an empirical formula of: where El, Al, P and Si are framework elements present as tetrahedral oxide units, “w” is the mole fraction of El and has a value from 0 to about 0.5, “x” is the mole fraction of Al and has a value from 0 to about 0.5, “y” is the mole fraction of P and has a value from 0 to about 0.5, and “z” is the mole fraction of Si and has a value from 0 to about 1, w+x+y+z=1 and “y” and “z” are not simultaneously zero, and the amount of amorphous component varies from 0 to about 100 wt. %, the process comprising providing at reaction conditions a reaction mixture comprising reactive sources of El, Al, P and Si per equation (1), adding to the mixture nutrient(s) per equation (1), to provide framework element(s) of the molecular sieve; carrying out the addition to reach the elements' critical supersaturation concentration thereby forming beads and continuing to further add nutrient(s) to obtain beads of a desired particle size.
