ABSTRACT:
A zeolitic material with a crystalline structure of MFI type has a ratio of silica to alumina which is lower than 26, and is hydrothermally prepared without organic template reagents or seeding procedures. Crystalline structure is obtained by forming a mixture of a silicon dioxide source, an alkali metal hydroxide, an aluminum source and water, all reactants with the following molar ratios: ##EQU1## where M is an alkali metal, and reacting the mixture at a temperature from 160.degree. to 180.degree. C. for 40-80 hours. The material is characterized by X-ray diffraction, and has good cracking activity and improved selectivity for gasoline octanes.
