A METHOD OF INCORPORATING SILICON ATOMS IN PLACE OF ALUMINIUM ATOMS IN THE CRYSTAL LATTICE OF A ZEOLITE OF THE FAUJASITE TYPE

摘要

Zeolites obtained by incorporating silicon atoms in place of aluminium atoms in the crystal lattice of a zeolite of the faujasite type by means of a halogenosilane at temperatures below 150 DEG C and subsequent washing are particularly suitable for the conversion of hydrocarbons, above all for cracking. They are distinguished by ultrastability and good activity.
