Embodiment 1
[0027] The high-efficiency wood granular activated carbon used for automobile carbon tanks in the present embodiment has a weight ratio of main raw material components of wood activated carbon powder: organic nano-based bentonite: water=1: 0.2: 0.85, and the three raw materials are stirred evenly and then granulated. After granulation and drying, physical activation is carried out. The woody activated carbon powder is mixed with aged wood chips and 85% thermal food-grade phosphoric acid according to the weight ratio of wood chips: thermal food-grade phosphoric acid=1:1.2. After fully stirring the static stains, it is activated by high-temperature carbonization, recycled, rinsed, dried, and powdered. It is columnar or spherical granular activated carbon, and the particle size and length are generally controlled at 2.0mm in particle size and 3-6mm in length.

Embodiment 2
[0045]The high-efficiency wood granular activated carbon used for automobile carbon tanks in the present embodiment has a weight ratio of main raw material components of wood activated carbon powder: organic nano-based bentonite: water = 1: 0.22: 0.9, and the three raw materials are stirred evenly and then granulated. After granulation and drying, physical activation is carried out. The woody activated carbon powder is mixed with aged wood chips and 85% thermal food-grade phosphoric acid according to the weight ratio of wood chips: thermal food-grade phosphoric acid=1:1.3. After fully stirring the static stains, it is activated by high-temperature carbonization, recycled, rinsed, dried, and powdered. It is columnar or spherical granular activated carbon, and the particle size and length are generally controlled at 2.0mm in particle size and 3-6mm in length.

Embodiment 3
[0063] The high-efficiency wood granular activated carbon used for automobile canisters in the present embodiment has a weight ratio of main raw material components of wood activated carbon powder: organic nano-based bentonite: water = 1: 0.25: 1.0, and the three raw materials are stirred evenly and then granulated. After granulation and drying, physical activation is carried out. The woody activated carbon powder is mixed with aged wood chips and 85% thermal food-grade phosphoric acid according to the weight ratio of wood chips: thermal food-grade phosphoric acid=1:1.4. After fully stirring the static stains, it is activated by high-temperature carbonization, recycled, rinsed, dried, and powdered. It is columnar or spherical granular activated carbon, and the particle size and length are generally controlled at 2.0mm in particle size and 3-6mm in length.
