Изучение свойств фосформодифицированного цеолитового катализатора

Abstract

The work presents literature data on zeolites of cracking catalyst components, a compar-ison of the specific surface area and pore volume of the initial and modified zeolite, a modi-fication of the zeolite component of the cracking catalyst with phosphorus. The structure and properties of samples based on ZSM-5 zeolites were studied. To assess the porous structure of the samples, the analysis of nitrogen adsorption – desorption isotherms at 77.4 K; cracking products were analyzed to assess the catalytic activity. The changes in the porous structure of the zeolite and the decrease in the total acidity of the modified catalyst are revealed and con-sidered.
