Abstract:
1. A method of making a crystalline molecular sieve composition having a pore size in the range of from about 2 to about 19 Å, said method comprising the steps of: (a) providing a mixture comprising at least one source of ions of tetravalent element (Y), at least one hydroxide source (OH and (b) treating said mixture with stirring at crystallization conditions sufficient to obtain a weight hourly throughput from about 0.005 to about 1 hr wherein said crystalline molecular sieve has a zeolite framework type comprising at least one of ABW, AEI, AEL, AET, AFI, AFO, CHA, EMT, FAU, FER, LEV, LTA, LTL, MAZ, MEL, MTT, NES, OFF, TON, VFI, MWW, MTW, MOR, EUO, *BEA, and MFS, wherein said weight hourly template efficiency is calculated by dividing the weight of the molecular sieve produced in the dried cake with the weight of the directing agent used in the synthesis mixture and the total time required for the crystallization as follows: and said tetravalent element oxide utilization is 0.85.
