Embodiment 1
[0017] A method for preparing nitrogen carbon molecular sieves from apple pomace, comprising the steps of:
[0018] Step 1: Pretreatment of raw materials, pretreatment of apple waste resources, after simple cleaning, put the apple waste into a high-speed mixer, add water, stir for 12 minutes at a speed of 1350rpm, and then remove the core part After extraction, the raw materials are made into dry powder by extrusion, drying and crushing, and the pretreated raw materials are obtained by sieving;
[0019] Step 2: carbonization, put the pretreated raw materials into the carbonization furnace, lay the raw materials naturally on the plane, raise the temperature to the carbonization temperature, and carbonize to obtain the final carbon molecular sieve carbon material.
[0020] The powder particle size of the pretreated raw material is 30-50 μm.
[0021] The laying thickness of the carbonized raw materials is 3-5mm.
[0022] The carbonization temperature is 980°C.
[0023] The fin...
