Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania stabilnego sorbenta CO2 na bazie modyfikowanego potasem ditlenku tytanu, który polega na tym, że wysuszony anatazowy ditlenek tytanu miesza się z 10 M roztworem KOH w stosunku wagowym 1 : 20, aż do czasu otrzymania jednolitej zawiesiny. Następnie materiał podgrzewa do temperatury 140°C, po czym po samoistnym ochłodzeniu do temperatury pokojowej zawiesinę kilkakrotnie przemywa się 0,1 M roztworem HCl nieustannie mieszając, do uzyskania pH silnie kwaśnego. Otrzymany materiał przemywa się wodą destylowaną do uzyskania pH obojętnego i suszy się w piecu w atmosferze powietrza przez 2 godziny w temperaturze 350°C, a następnie mieli. Istota zgłoszenia polega na tym, że stosuje się ditlenek tytanu o zawartości anatazu 100% i węgla 1,06% wagowych, a materiał podgrzewa do temperatury 140°C przez 12, 24 lub 48 godzin.The subject of the application is a method for obtaining a stable CO2 sorbent based on potassium-modified titanium dioxide, which consists in the fact that dried anatase titanium dioxide is mixed with a 10 M solution of KOH in a 1: 20 weight ratio until obtaining a uniform suspension. The material is then heated to 140 ° C, after which after spontaneous cooling to room temperature, the suspension is washed several times with 0.1 M HCl solution, stirring continuously until a strong acidic pH is obtained. The resulting material is washed with distilled water until neutral pH and dried in an oven in an air atmosphere for 2 hours at 350 ° C, followed by milling. The nature of the application is that titanium dioxide with anatase content of 100% and carbon 1.06% by weight is used, and the material is heated to 140 ° C for 12, 24 or 48 hours.
