NOVELTY - Active carbon gas adsorbent comprises 150-160 pts. wt. of pine nut shell, 3-4 pts. wt. of graphene, 10-15 pts. wt. of attapulgite, 8-10 pts. wt. of ferric chloride, 8-10 pts. wt. of sodium perborate, 10-15 pts. wt. of citric acid, 4-5 pts. wt. of modified diatomite including 140-150 pts. wt. of diatomite, 10-12 pts. wt. of alum, 1-2 pts. wt. of nano-carbon, 1-2 pts. wt. of barley oil, 2-3 pts. wt. of ascorbic acid, 1-2 pts. wt. of citric acid, 2-3 pts. wt. of sodium tripolyphosphate and 2-3 pts. wt. of ginsenoside powder, and proper amount of water. USE - The active carbon gas adsorbent is useful for catalyzing and decomposing organic matter. ADVANTAGE - The active carbon gas adsorbent can be easily and economically prepared in an eco-friendly manner. DETAILED DESCRIPTION - Active carbon gas adsorbent comprises 150-160 pts. wt. of pine nut shell, 3-4 pts. wt. of graphene, 10-15 pts. wt. of attapulgite, 8-10 pts. wt. of ferric chloride, 8-10 pts. wt. of sodium perborate, 10-15 pts. wt. of citric acid, 4-5 pts. wt. of modified diatomite including 140-150 pts. wt. of diatomite, 10-12 pts. wt. of alum, 1-2 pts. wt. of nano-carbon, 1-2 pts. wt. of barley oil, 2-3 pts. wt. of ascorbic acid, 1-2 pts. wt. of citric acid, 2-3 pts. wt. of sodium tripolyphosphate and 2-3 pts. wt. of ginsenoside powder, and proper amount of water. The modified diatomite is prepared by placing diatomite in a calcining furnace at 540-560 degrees C for 3-4 hours, then adding 12-15 wt.% of hydrochloric acid solution to soak for 4-5 hours, filtering the soaked solution, washing the filtered solution by clean water, drying the mixture, adding nano carbon, ascorbic acid, citric acid and alum with water, grinding the mixture to obtain slurry, spray drying the mixture to the dry powder, and mixing, grinding and dispersing the other remaining raw material. An INDEPENDENT CLAIM is included for preparing active carbon gas adsorbent comprising crushing the pine nut shell in a carbonization furnace at 600-700 degrees C for 2-3 hours, adding graphene, ferric chloride and citric acid in the water into mud, heating the mixture at 75-85 degrees C, grinding the mixture into 200-300-mesh slurry for 2-3 hours, then washing with clean water, drying the mixture, and uniformly mixing and dispersing the other remaining raw material.
