Abstract:
1. A process for forming a calcined zeolite with uniform intracrystal textural pores, which comprises: (a) reacting a porogen comprising a silane modified polymer, wherein the silane modified polymer comprises a polymer covalently linked to a silane modifier and the mass of the polymer per mole of the silane modifier is at least 100 grams per mole, in a mixture of an alumina source and a silica source to form a porogen-linked aluminosilicate reaction mixture; (b) digesting the reaction mixture to form zeolite crystals with the silane modified polymer porogen occluded within the crystals; and (c) removing the occluded intracrystal porogen from the zeolite crystals by calcination to form the calcined zeolite with the uniform intracrystal textural pores.
