Method of making seed solution useful in zeolite catalyst manufacture. |
| 摘要 |
<p>The useful storage life of a clear solution of seeds used to initiate the crystallization of zeolite in porous microspheres of calcined clay is increased by adding sodium silicate solution to a matured seed solution. Seed solution which has become cloudy or gelled can be clarified by adding sodium silicate solution.</p> |
