摘要: 利用草酸对NaY分子筛进行脱铝改性,然后进行液相离子交换制得 HY分子筛。并用HY和NaY 分子筛进行FCC汽油的脱硫效果对比。结果表明,HY分子筛吸附脱硫效果明显好于NaY分子筛;成型HY分子筛比未成型HY分子筛的吸附脱硫效果好,HY分子筛中添加质量分数为25%的γAl2O3比不添加γAl2O3的 HY 分子筛的吸附脱硫效果好。HY分子筛静态吸附脱硫最佳时间为6 h,最佳剂油质量比为1∶3,最佳质量空速为0 .5 h - 1,再生后的成型 HY( w (γAl2O3) = 25% )能恢复到原来吸附能力的92 .69%。

Abstract:

NaY zeolite was modified with oxalic acid. The HY zeolite were obtained by liquid phase ion exchange. And two Y zeolites (NaY,HY) were compared by selective adsorptive desulfurization from FCC gasoline.The results show that the HY zeolite adsorptive desulfurization effect is better than NaY zeolite. The molded HY zeolite is more effective than the unmolded HY zeolite. HY zeolite which contained 25%(mass fraction) γAl2O3 is more effective than HY zeolite which did not. When the static adsorptive desulfurization time of HY zeolite is 6 h,mass ratio of solid and fuel is 1∶3, WHSV is 0.5 h-1 ,the effect of HY is the best. The rate of regeneration of the molded HY zeolites is 92.69%.
