Abstract:
Salts in catalyst supports were studied. The distribution was practically independent of the conditions of impregnation and drying, but the decisive factor was the interaction salt-support even in the case of nonspecific interaction. Experiments were done with the silica gels KSK and KSM, γ-Al2O3, and an amorphous com. aluminosilicate cracking catalyst as supports. The diffractometric study was done in the DRON-1 app. The dispersion of salts in the pores of the supports resulted in formation of high-temperature modifications and in partial or total amorphization. The content of the crystal phase decreased in the case of 10% solutions in the series KCl, RbCl, NaCl, CsCl, LiCl, and RbNO3, NaNO3, CsNO3, KNO3, LiNO3 in the case of γ-Al2O3 with 90 Å pores; and in the series NaCl, KCl, LiCl, and CsNO3, RbNO3, NaNO3, KNO3, LiNO3 in the case of SiO2 with 20 Å pores. In the 5-20% concentration ranges, the sequences remained practically const. The amorhous phase of the salts in the pores was stable, i.e., remained during a year of storage at room temperature
