分子筛催化剂成型条件对其抗压强度的影响

介绍了Y分子筛成型步骤，考察了Y分子筛与拟薄水铝石质量比、胶溶剂品种及含量、升温速度、水粉比等对催化剂成型后抗压强度的影响。结果表明，Y分子筛与拟薄水铝石质量比3：1，硝酸为胶溶剂，其含量5％，缓慢升温，升温速度100℃／h，水粉比0．85，干燥温度110℃，焙烧温度550℃，在此条件下，成型分子筛抗压强度最好。

The Effects of Forming Conditions for Zeolite on Its Compressive Strength

The forming steps for zeolite were introduced.The effects of conditions such as mass ratio of Y zeolite to pseudobochmite,kinds and content of peptizator,mass ratio of water to powder on the compressive strength after catalyst forming were examined.The result showed that the formed Y zeolite had the best compressive strength under the conditions as follows: mass ratio of Y zeolite to pseudobochmite was 3:1,nitric acid was used as peptizator with the content of 5%,the temperature rised steadily with the speed of 100 ℃ per hour,mass ratio of water to powder was 0.85,drying temperature was 110 ℃,calcination temperature was 550 ℃.
