Claim:
1. A method of producing a zeolite comprising: reacting a gel and zeolite seed crystals to produce a zeolite having the same kind of skeletal structure as the zeolite seed crystals; wherein: the gel comprises a silica source, an alumina source, an alkali source and water; the gel is capable of synthesizing a zeolite without the use of the zeolite seed crystals, wherein the zeolite synthesized without the use of the zeolite seed crystals has a different kind of skeletal structure than the zeolite seed crystals and comprises one or more building units of zeolite; the zeolite seed crystals comprise one or more composite building units of zeolite; the zeolite seed crystals and the zeolite synthesized without the use of zeolite seed crystals comprise at least one equivalent composite building unit of zeolite; MFI zeolite, MEL zeolite, MSE zeolite, MTW zeolite, TUN zeolite, MFS zeolite, MOZ zeolite, EON zeolite, or LTF zeolite is used as the zeolite seed crystals; and wherein the reacting step occurs without the use of an organic structure-directing agent.
