Embodiment 1
[0032] A method for preparing hydrothermal charcoal from genotype ZPX Cizhu liangshan, is characterized in that, comprises the following steps:
[0033] Step 1. Take the stalks at the DBH of the genotype ZPX Liangshan Cizhu, remove the bamboo rings, take the internodes, wash the surface with distilled water, dry them in an oven at 50°C for 96 hours, split them into small pieces, and then crush them with a pulverizer. Pass through a 200-mesh sieve, collect, and obtain bamboo powder, then add 32g of bamboo powder and 1600mL of water into the autoclave, heat up to 220°C, keep warm for 4h; naturally cool to room temperature;
[0034] Step 2. Use a centrifuge to centrifuge the feed liquid obtained in Step 1 at 25°C, 5000rpm, 10min, pour off the supernatant, add absolute ethanol, shake and centrifuge again, repeat the above process until the supernatant is colorless Transparent, then dry the solid at 50°C to constant weight to obtain hydrothermal carbon (ZPX-220). After testing, the...

[0040] A method for preparing hydrothermal charcoal from genotype 215 Cizhu liangshan, is characterized in that, comprises the following steps:
[0041] Step 1: Take the stalks at the DBH of genotype 215 Liangshan Cizhu, remove the bamboo rings, take the internodes, wash the surface with distilled water, dry in an oven at 50°C for 96 hours, split into small pieces, and then crush them with a pulverizer. Pass through a 200-mesh sieve, collect, and obtain bamboo powder, then add 32g of bamboo powder and 1600mL of water into the autoclave, heat up to 220°C, keep warm for 4h; naturally cool to room temperature;
[0042]Step 2. Centrifuge the feed liquid obtained in step 1 at 25°C, 5000rpm, 10min, pour off the supernatant, add absolute ethanol, vibrate and centrifuge again, and repeat the above process until the supernatant is colorless. Transparent, then the solid was dried at 50°C to constant weight to obtain hydrothermal carbon (215-220). After testing, the specific surface area...
