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.degree. C. and 500.degree. 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.
