| titleOfInvention | P-A type molecular sieve prepared from spontaneous combustion coal gangue and preparation method thereof |
| abstract | A P-A type molecular sieve prepared by using spontaneous combustion coal gangue and ｃA preparation method thereof belong to the field of porous material synthesis. The specific surface areｃA of the P-A type molecular sieve prepared by the spontaneous combustion coal gangue is 4.5-6.5m 2 ·g ‑1 The grain diameter is 3.18-4.25 um. It is composed ofThe preparation method comprises the following steps: and respectively adding sodium aluminate and pulverized spontaneous combustion coal gangue into the sodium hydroxide aqueous solution, heating the obtained mixture, cooling, performing solid-liquid separation, and drying to obtain the P-A type molecular sieve. The raw materials are cheap and easy to obtain, the operation conditions are loose, and the purity of the prepared P-A type molecular sieve is higher and can reach 50-65%. Meanwhile, a new way is provided for recycling, refining and efficiently utilizing the coal gangue, the effect of changing waste into valuable is achieved, and the requirement of environmental protection and low carbon is met. |
