The present invention includes a microporous or mesoporous composition of matter in which the composition is formed continuously or semi-continuously in a heated reactor zone, including a rotary calciner or a rotary screw as a means for conveying the synthesis mixture, at a temperature between 200&#xb0; C. and 500&#xb0; C. with a residence time less than 24 hours. The reagents are solid and liquid reagents in which the solid reagents have a weight percent between 45% and 98% of the total reagents. The invention also includes a continuous or semi-continuous process for the hydrothermal manufacture of the microporous or mesoporous composition.

High solids materials processing

This invention relates to a novel synthetic porous crystalline molecular sieve material, MCM-65, to a reaction mixture and method for its preparation, and to use of the MCM-65 in catalytic conversion of organic compounds. The crystalline material exhibits a distinctive X-ray diffraction pattern as shown in Table 1.

Crystalline molecular sieve composition MCM-65, its synthesis and use

A new synthetic porous crystalline material, designated EMM-1, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making EMM-1 in the presence of HF using various organic nitrogen compounds as directing agents. Aluminum-containing EMM-1 can be produced either by inclusion of Al in the synthesis, or by incorporation of B or Ga in the synthesis, followed by post treatment with aluminum nitrate or other sources of Al. EMM-1 is useful as an acid catalyst and as an adsorbent.

Synthetic porous crystalline material, EMM-1, its synthesis and use

In a process for synthesizing a porous crystalline material, a mixture capable of forming said material is prepared wherein the mixture comprises sources of water, an oxide of a tetravalent element Y, preferably silicon, an oxide of a trivalent element X, wherein X is selected from the group consisting of aluminum, boron, gallium, iron, and indium, fluoride ions, and an organonitrogen cation RN capable of directing the synthesis of said material, wherein the molar ratio of fluoride ions to organonitrogen cations RN in said mixture is greater than 1.15 m but less than 2.5 m. The mixture is maintained under crystallization conditions until crystals of said material are formed and the resultant crystalline material is recovered.
