Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania materiału węglowego, według wynalazku, do adsorpcji gazów cieplarnianych, który polega na mieszaniu w stosunku wagowym 1 : 0,1 - 5 wysuszonego źródła węgla aktywnego z wodnym roztworem aktywatora lub zwilżonego źródła węgla aktywnego ze stałym aktywatorem. Jako aktywator stosuje się KOH i/lub NaOH i/lub Na<sub>2</sub>CO<sub>3</sub> i/lub K<sub>2</sub>CO<sub>3</sub>, pozostawieniu mieszaniny na czas 0 — 24 godzin. Następnie suszy się otrzymaną mieszaninę, karbonizuje w atmosferze gazu obojętnego chemicznie, przemywa i suszy. Istota wynalazku polega na tym, że jako źródło węgla aktywnego stosuje się wysuszony materiał, który uzyskuje się w wyniku syntezy hydrotermalnej polegającej na umieszczeniu w autoklawie zawiesiny skórek cytrusowych w wodzie lub zawiesiny skórek cytrusowych i kwasu szczawiowego w stosunku wagowym 1 : 0,1 - 5 (odpowiednio skórki cytrusowe : kwas szczawiowy) w wodzie na czas 0 — 48 godzin, w temperaturze 105 — 220°C, przy czym otrzymuje się materiał węglowy w postaci sfery węglowych o wysokiej powierzchni właściwej. W wynalazku można stosować skórki z różnych cytrusów i ich mieszaniny, np. cytrynowe i/lub pomarańczowe i/lub grejpfrutowe i/lub z pomelo.The subject of the application is a method of producing a carbon material, according to the invention, for the adsorption of greenhouse gases, which consists in mixing in a weight ratio of 1:0.1 - 5 a dried activated carbon source with an aqueous activator solution or a wetted activated carbon source with a solid activator. The activator is KOH and/or NaOH and/or Na<sub>2</sub>CO<sub>3</sub> and/or K<sub>2</sub>CO<sub>3</sub >, leaving the mixture for 0 - 24 hours. The resulting mixture is then dried, carbonized in an atmosphere of chemically inert gas, washed and dried. The essence of the invention lies in the fact that as a source of activated carbon, a dried material is used, which is obtained as a result of hydrothermal synthesis consisting in placing in an autoclave a suspension of citrus peels in water or a suspension of citrus peels and oxalic acid in a weight ratio of 1: 0.1 - 5 (correspondingly, citrus peels: oxalic acid) in water for 0 - 48 hours at a temperature of 105 - 220°C, obtaining carbon material in the form of carbon spheres with a high specific surface area. Various citrus peels and mixtures thereof can be used in the invention, e.g. lemon and/or orange and/or grapefruit and/or pomelo.
