Method for improving specific surface area and adsorption performance of opoka

[0017] Example 1

[0018] (1) take by weighing natural protein soil 9g, NaOH 1g respectively, utilize vortex mixer to stir 30min, make it mix well, obtain preliminary protein soil powder;

[0019] (2) Weigh 1.9g MgCl 2 Mix it with 2.7g glycerol to make 1L mixed solution, take 50mL mixed solution, mix it with the preliminary protein soil powder evenly, and then add it into a 75mL ceramic crucible according to the solid-liquid mass ratio of 1:5. Put it in a high-pressure reactor and react at 160 °C for 12 hours; oxygen is not released during the heating process, so as to ensure that the reaction process is in an aerobic environment;

[0020] (3) After the reaction is completed, the protein soil is taken out and cooled to room temperature. After filtration, it is fully dried at 100° C., and pulverized to below 74 μm using a pulverizer to finally obtain protein soil powder with high specific surface area and adsorption performance.

[0021] Example 2

[0022] This example is basically the same as Example 1, except that the consumption of natural protein soil is 8.5g, and the consumption of NaOH is 1.5g.

[0023] Example 3

[0024] This example is basically the same as Example 1, the difference is: the consumption of natural protein soil is 9.5g, NaOH is replaced with CaO, and its consumption is 0.5g, the autoclave reaction temperature is 180 ℃, and the reaction time is unchanged.
