氟硅酸铵对小晶粒Y分子筛加氢裂化性能的影响OA北大核心CSCDCSTPCD
Effects of (NH4)2SiF6 treatment on performances of small crystal grain Y zeolite in hydrocracking
采用不同浓度的氟硅酸铵溶液对小晶粒Y分子筛进行处理，考察了氟硅酸铵浓度对小晶粒Y分子筛物化性质和加氢裂化性能的影响。利用XRD，NH3-TPD，FTIR，SEM，27Al MAS NMR等手段对改性分子筛进行表征；以正十二烷为模型化合物考察催化剂的加氢裂化性能。实验结果表明，当氟硅酸铵浓度为0.3 mol/L时，NFY-3分子筛试样的结晶度和比表面积最大，继续地提高氟硅酸铵浓度会破坏分子筛的晶体结构；随氟硅酸铵浓度的增加，分子筛的脱铝量逐渐增大，…查看全部>>
Small crystal grain Y zeolite was modified by treatment with ammonium fluorosilicate solutions and then the modified zeolites were used in preparing hydrocracking catalysts. The influences of the ammonium fluorosilicate concentration on the physicochemical properties of the modified zeolites and the hydrocracking performances of the catalysts were investigated. The modified zeolite samples were characterizated by means of XRD,low-temperature nitrogen adsorpt…查看全部>>
