摘要：
Sulfur-reducing additives for fluid catalytic cracking (FCC) catalysts based on mesoporous aluminosilicates Al-SBA-15 and Al-SBA-16 were synthesized and characterized using FTIR spectroscopy, transmission electron microscopy, low-temperature N-2 adsorption/desorption, and thermally programmed desorption of NH3. Catalytic experiments were performed using a commercial zeolite-containing FCC catalyst and the additives (10 wt.%). It was found that all synthesized materials were active for reducing sulfur in liquid catalytic cracking products. The S content in the liquid cracking products obtained using an additive of 3% La-Al-SBA-15/Al2O3 (50:50) decreased by 36% as compared to the same parameter obtained using the commercial catalyst with no additive.
