  • Publication number: 20080045767
    Abstract: A method is disclosed of synthesizing a crystalline material comprising a CHA framework type molecular sieve and having a composition involving the molar relationship: (n)X2O3:YO2, wherein X is a trivalent element; Y is a tetravalent element; and n is from 0 to less than 0.01. The method comprises preparing a reaction mixture capable of forming said material, said mixture comprising a source of water, a source of an oxide of a tetravalent element Y and optionally a source of an oxide of a trivalent element X, wherein the reaction mixture is substantially free of fluoride ions added as HF; maintaining the reaction mixture under conditions sufficient to form crystals of the crystalline material; and than recovering the crystalline material. The reaction mixture comprises either a specific directing agent for directing the formation of a CHA framework type molecular sieve and/or a H2O:YO2 molar ratio of greater than 20.

  • Publication number: 20030190260
    Abstract: A combinatorial chemistry reactor system for the parallel processing of reaction mixtures. The system comprises a frame, a head mounted in fixed position on the frame, and a reactor block having a plurality of wells therein for containing reaction mixtures. The reactor block is movable with respect to the head between a first position in which the reactor block and head are assembled for conducting reactions in the wells and a second position in which the reactor block is removed from the head for providing access to the vessels. Gaps in the reactor block between the wells serve to thermally isolate the wells from one another. Other features relating to pressure relief, reactor block temperature control, and sensor mounting are also disclosed.
