Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania sorbentu do usuwania zanieczyszczeń organicznych z wód z użyciem popiołu lotnego ze spalania węgla oraz kwasu solnego. Sposób wytwarzania sorbentu polega na tym, że popiół lotny ze spalania węgla kamiennego, zawierający niespalony węgiel w ilości 20% - 30% miesza się z rozdrobnionym haloizytem w proporcji 75—80:25—20 w temperaturze 18°C — 25°C przez czas od 5 do 15 min. do uzyskania jednolitej masy. Średnica ziaren haloizytu wynosi od 0,2 mm do 0,06 mn. Następnie masę poddaje się granulacji z dodatkiem pyłu z klinkieru w ilości od 25% wag. do 30% wag., w stosunku do sporządzonej masy, w obecności wody o temperaturze od 18°C do 25°C w ilości do uzyskania granul o wielkości 1 — 8 mm, następnie granule suszy się i przesiewa na sitach o wielkości oczek 2 — 4 mm. W kolejnym etapie granule aktywuje się przy użyciu 0,4 - 0,5 molowego roztworu kwasu solnego w temperaturze 65°C - 70°C przez 10 - 15 godzin na łaźni wodnej, gdzie masa granul w stosunku do objętości roztworu kwasu solnego wynosi od 40 g/L do 60 g/L, a następnie pozostawia na co najmniej 9 godzin w temp. 18°C — 25°C i przepłukuje kilkukrotnie wodą redestylowaną i suszy w temperaturze 90°C — 110°C do 24 godzin.The subject of the application is a method for producing a sorbent for removing organic pollutants from water using fly ash from coal combustion and hydrochloric acid. The method for producing the sorbent involves mixing fly ash from hard coal combustion, containing 20%-30% unburned carbon, with crushed halloysite in a 75-80:25-20 ratio at a temperature of 18°C-25°C for 5 to 15 minutes until a uniform mass is obtained. Halloysite grain diameter ranges from 0.2 mm to 0.06 mm. The mass is then granulated with the addition of clinker dust in an amount of 25% by weight. up to 30% by weight, relative to the prepared mass, in the presence of water at a temperature of 18°C to 25°C in an amount to obtain granules with a size of 1—8 mm, then the granules are dried and sieved on sieves with a mesh size of 2—4 mm. In the next stage, the granules are activated using a 0.4—0.5 molar solution of hydrochloric acid at a temperature of 65°C—70°C for 10—15 hours in a water bath, where the mass of the granules in relation to the volume of the hydrochloric acid solution is from 40 g/L to 60 g/L, and then left for at least 9 hours at a temperature of 18°C—25°C and rinsed several times with redistilled water and dried at a temperature of 90°C—110°C for up to 24 hours.
