ABSTRACT:
A novel siliceous molecular sieve material is described for use as catalyst, along with a process for its production. The sieve material is unique in having a bimodal pore size distribution with micropores having diameters in the range from 5 to 12 .ANG. and uniformly sized mesopores having diameters in the range from 20 to 80 .ANG.. It is prepared by first preparing two reaction solutions, the first solution containing a source of silica and the second solution containing a quaternary ammonium surfactant having a hydrophilic ammonium group and a linear hydrophobic hydrocarbon chain. The two solutions are combined and the solid product obtained at room temperature is subjected to a two-stage heat treatment.
