摘要
利用响应曲面法对影响Ni/ZnO-SiO_2复合氧化物制备工艺的主要因素:活性金属组分比例、成胶pH值、老化时间进行试验设计。以Ni/ZnO-SiO_2复合氧化物用于低硫石脑油吸附脱硫处理中,产物硫含量为响应函数,建立相应的数学模型,优化试验方法。得到的最佳试验条件为:活性金属组分比例(Ni/Zn)为1.09、成胶pH值为5、老化时间为5h。此时Ni/ZnO-SiO_2复合氧化物对低硫石脑油的吸附脱硫性能为最优。Box-Behnke实验设计法用于Ni/ZnO-SiO_2复合氧化物制备工艺优化筛选是可行的,数学模型的预测值与实验观察值相符。
The best test condition was obtained： proportion of the active metal component was 1.09, pH value was 5, aging time was 5h. At this point,adsorptive desulfurization performance of Ni/ZnO-SiO_2 composite oxide composite oxide was best. Box-Behnke experimental design method is feasible to used to optimize Ni/ZnO-SiO_2 composite oxide preparation is feasible, the mathematical model prediction values agree well with the experimental observation.
