[0021]Weigh 100g of fly ash and 80g of expanded graphite, mix and grind for 6 minutes, pass through a 100-mesh sieve, collect the sifted powder, pour the sifted powder into a beaker, place it in a water bath at 45°C and stir for 3 minutes, add 12 mL of mass to the beaker Hydrochloric acid with a fraction of 10% and 16mL of hydrogen peroxide with a mass fraction of 15%, continue to heat and mix and stir for 1 hour, wait until the reaction is complete until no gas escapes, stop heating, rinse the sieved powder with deionized water, and remove the remaining hydrochloric acid and hydrogen peroxide. Finally, put it in an oven at 65°C for 20 minutes to obtain the modified mixed powder. Mix the modified mixed powder and magnetite powder for 10 minutes according to the mass ratio of 3:1 to obtain a self-made magnetic mixture. The shells and crab shells were mixed and stirred for 8 minutes to obtain a mixture. Continue to add the mixture to a fermenter with 0.5% biogas slurry of the mix...

[0023] Weigh 110g of fly ash and 90g of expanded graphite, mix and grind for 7 minutes, pass through a 100-mesh sieve, collect the sieved powder, pour the sifted powder into a beaker, place it in a water bath at 55°C and stir for 4 minutes, add 15 mL of mass to the beaker Hydrochloric acid with a fraction of 10% and 18mL of hydrogen peroxide with a mass fraction of 15%, continue to heat and mix and stir for 1.5h, wait until the reaction is complete until no gas escapes, stop heating, rinse the sieved powder with deionized water, and remove the remaining hydrochloric acid and hydrogen peroxide , and finally placed in an oven at 70°C for 25 minutes to obtain a modified mixed powder. The modified mixed powder and magnetite powder were mixed and stirred for 11 minutes according to a mass ratio of 3:1 to obtain a self-made magnetic mixture. Shrimp shells and crab shells were mixed and stirred for 9 minutes to obtain a mixture. Continue to add the mixture into a fermenter with 0.5% b...
