実験手順
The process 300 begins with a reaction step 308 wherein the aluminum hydroxide is fed, either as a wet cake or as a dry powder, with a slurry water 310 and an acid 312 into a pressure cooker. The acid 312 can be sulfuric acid. The temperature is raised to approximately 150° C. to produce an aluminum sulfate in a molten hydrate form. The pressure is held high enough to maintain a liquid state, e.g., 1100 kilo-Pascals. The residence time is between one to ten minutes, and preferably about two minutes.
