正交试验对沸石合成条件的优化
Study on the optimal conditions on zeolite synthesis process with orthogonal experiment
摘要
Abstract
Fly ash was used as raw material for zeolite synthesis, the effects of NaOH concentration, temperature and liquid/solid ratio on zeolite CEC values were analyzed, and the optimal condition was revealed by orthogonal experiment. The single factor experiment showed the acceptable conditions were attained at 150 ℃ with NaOH concentration of 2 mol/ L and liquid/solid ratio of 10 mL/g. The achievement of L16(45) orthogonal experiment indicated the most important factor was NaOH concentration followed by temperature, the optimal experimental group was of NaOH concentration 2 mol/L and liquid/solid ratio 10 mL/g at 150℃ with attained CEC value of 144 mmol/100 g.关键词
