example 1
[0027] Put 200mL of cotton pulp black liquid with 25% solid mass content into a reactor with a gas valve, seal the reactor, and introduce carbon dioxide gas into the reactor through the gas valve at a ventilation rate of 40mL / min. The ventilation continues 10min, close the vent valve, heat up to 200℃, keep the temperature for 7h to obtain the reaction material; mix the above-mentioned reaction material and quicklime at a mass ratio of 10:1, heat up to 80℃, digest for 4min to obtain decaustic slurry, The decaustic slurry was filtered and separated to collect the filter residue. The filter residue was placed in an oven set at 100℃ and dried for 4 hours to obtain hydrothermal coke; 200mL of potassium permanganate solution with a mass concentration of 7g / mL was prepared, and the mass fraction was 85 % Concentrated sulfuric acid solution was added to the potassium permanganate solution, the pH of the potassium permanganate solution was adjusted to 2 to obtain an acid potassium perman...

[0031] Put 250mL of cotton pulp black liquid with 25% solid mass content into a reactor with a gas valve, seal the reactor, and introduce carbon dioxide gas into the reactor through the gas valve at a ventilation rate of 50 mL / min, and the ventilation continues 15min, close the vent valve, heat up to 220℃, keep the temperature for 8h to obtain the reaction material; mix the above-mentioned reaction material and quicklime at a mass ratio of 10:1, heat up to 90℃, digest for 5min to obtain a decaustic slurry. The decaustic slurry is filtered and separated to collect the filter residue. The filter residue is placed in an oven set at 110°C and dried for 10 hours to obtain hydrothermal coke; prepare 250 mL of potassium permanganate solution with a mass concentration of 10 g / mL, and the mass fraction is 85 % Concentrated sulfuric acid solution was added to the potassium permanganate solution, the pH of the potassium permanganate solution was adjusted to 3 to obtain the acid potassium p...
