Microwave irradiated activated carbon made from flax shavings

Microwave irradiated flax shavings to produce activated carbon takes flax shavings as raw materials, and uses microwave radiation to prepare activated carbon.

Figure 4-19 The process flow of making activated carbon from flax shavings under microwave radiation

After the flax shavings are dried, they are immersed in a certain concentration of zinc chloride solution for a period of time, and the materials are put into the microwave equipment, and irradiated under a certain microwave power, and the obtained product is pickled, rinsed, dried and crushed , Get powdered activated carbon

The optimal process conditions for preparing activated carbon by microwave irradiated flax shavings zinc chloride method are: raw material amount 15g, immersion time 24h, zinc chloride concentration 20%, microwave power 600W, activation time 12min

④Iron-loaded phenolic resin-based activated carbon Weigh 10.

⑤The process flow diagram of preparing activated carbon from betel nut residue is shown in Figure 4-20

Figure 4-20 Process flow for preparing activated carbon from betel nut residue

The betel nut residue is washed, dried, pulverized, passed through a 383μm sieve, and added with a 25%-30% activator ZnCl ₂ solution at a liquid-solid ratio of 5:1 , mixed, stirred and immersed for about 24h, at 550～Chemical charcoal activation with nitrogen gas at 600℃ for 4.
