| titleOfInvention | The preparation method and product of niobium modified activated aluminum oxide for purifying formaldehyde and application |
| abstract | The niobium modified activated aluminum oxide and its preparation method and application that the invention discloses a kind of for purifying formaldehyde, activated alumina is placed in certain density niobium salt solution, appropriate hydrochloric acid is added, is filtered after ultrasonic 5-12h, the sample of acquisition uses after passing through two kinds of Temperature Treatments respectively.For the activated alumina of low concentration (0 < niobium concentration≤0.012 mol/L) niobium salt treatment, it is placed in 50 o It is applied in purifying formaldehyde after dry 12 h in C baking oven；For the activated alumina of rather high concentration (0.012 mol/L < niobium concentration≤0.020 mol/L) niobium salt treatment, it is placed in 50 o It is roasted in air atmosphere after dry 12 h in C baking oven, maturing temperature is in 400-500 o Between C, calcining time 4-5 h.The preparation method that the present invention announces is applicable in the modification of activated alumina and molecular sieve, and performance can be improved to 2-5 times of corresponding untreated samples, and in changes in environmental conditions, be not easy to be desorbed, avoid secondary pollution. |
