Preparation method of beta ''-Al2O3 particles
The invention discloses a preparation method of a beta ''-Al2O3 granular material. The preparation method specifically comprises the following steps: mixing a sodium source and ammonia water, adding the mixture into an aluminum source, adding a proper amount of deionized water, uniformly stirring, and adding different amounts of stabilizers into the solution; further mixing a sodium source and an aluminum source by utilizing spray drying, drying to obtain powder, and calcining for a certain time by using a tubular furnace at a proper temperature to obtain beta ''-Al2O3 particles; the beta ''-Al2O3 particle material is prepared by using a one-step method, compared with a traditional two-step method, the time for preparing a precursor is shortened, a spray dryer is used for drying, a sodium source and an aluminum source are further mixed, and the sodium source can better enter a system through constant-temperature calcination at a certain temperature. Compared with a product obtained by calcining powder obtained by drying in a drying oven, the product disclosed by the invention not only can save time and manpower resources, but also does not bring in other impurities in the experiment process.
本发明公开了一种β’’‑Al2O3颗粒材料的制备方法。具体制备过程如下：将钠源与氨水混合后加入到铝源中，加入适当的去离子水并搅拌均匀，再将不同量的稳定剂加入到溶液中。利用喷雾干燥进一步将钠源与铝源混合并进行干燥得到粉末，再使用管式炉在适当的温度下煅烧一定的时间得到β’’‑Al2O3颗粒。本专利使用了一步法制备β’’‑Al2O3颗粒材料，与传统两步法相比减少了制备前驱体的时间，且本发明中使用了喷雾干燥机进行干燥并进一步将钠源与铝源混合，在一定温度下恒温煅烧就能够让钠源更好地进入体系中。通过与烘箱干燥得到的粉末煅烧后得到的产品对比，可以看出该发明中的产品不仅可以节省时间、人力资源，且本发明实验过程中不带入其他杂质。
