[0024] Example
[0025] A renewable porous carbon adsorbent for toluene adsorbent, the feedstock is made of carbon black, binder, and is carried out under the action of the aperture agent.
[0026] The carbon black, the binder is 95: 5, and the binder is a flour paste.
[0027] The pore agent is (NH) 4 ) 2 CO 3 Aqueous solution, said (NH 4 ) 2 CO 3 The amount of addition is 20% of carbon black and the total mass of the binder.
[0028] At the same time, the present invention also discloses a method for preparing a renewable porous carbon adsorbent for toluene adsorbent, including the following steps:
[0029] S1: Preparation of the precursor: Black carbon black grinding and dried in an oven at 70 ° C, and 0.05 g of the flour is placed in a crucible containing 0.1 ml of deionized water, and 0.95 g of carbon black powder, stirred after stirring Add (NH) 4 ) 2 CO 3 Aqueous solution (NH 4 ) 2 CO 3 The mass is 0.2g, thoroughly mixed, and the precursor is obtained;
[0030] S2: Dry: Place
