Abstract
Przedmiotem zgłoszenia jest sposób sorpcji CO2 fazy gazowej, z wykorzystaniem modyfikowanego ditlenku tytanu jako adsorbenta, który modyfikuje się w ten sposób, że miesza się go z 10 M roztworem KOH w stosunku wagowym 1 : 20, aż do czasu otrzymania jednolitej zawiesiny. Następnie materiał odgrzewa się w temperaturze 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. Potem materiał przemywa się wodą destylowaną do uzyskania pH obojętnego i tak otrzymany nanomateriał suszy się w piecu w atmosferze powietrza przez 2 godziny w temperaturze 350°C, a następnie mieli. Istota zgłoszenia polega na tym, że do rekcji hydrotermalnej stosuje się ditlenek tytanu o zawartości anatazu 100% i zawartości węgla 1,06%, materiał ogrzewa się w temperaturze 140°C przez 12, 24 lub 48 godzin. Otrzymane sorbenty modyfikuje się dodając je do roztworu tetraetylenopentaminy i wody w stosunku wagowym 1 : 10 i tak otrzymaną zawiesinę miesza się przez 6 godzin, a następnie suszy przez 2 godziny w 80°C. Korzystnie adsorbent przed użyciem do sorpcji CO2 wygrzewa się w gazie inertnym w temperaturze 100°C z szybkością ogrzewania 5°C/min. Jako gaz inertny stosuje się azot. Korzystnie adsorbent po przeprowadzeniu desorpcji w temperaturze 100°C przez 1 godzinę stosuje się ponownie do sorpcji CO2.The subject of the application is a CO2 phase gas sorption method, using modified titanium dioxide as an adsorbent, which is modified in such a way that it is mixed with a 10 M KOH solution in a weight ratio of 1: 20, until a uniform suspension is obtained. Then the material is heated at 140 ° C, after which after spontaneous cooling to room temperature, the suspension is washed several times with 0.1 M HCl solution, stirring constantly until a strongly acidic pH is obtained. Then the material is washed with distilled water to obtain a neutral pH and the nanomaterial thus obtained is dried in an oven in an air atmosphere for 2 hours at 350 ° C and then ground. The essence of the application is that for hydrothermal reaction titanium dioxide with anatase content of 100% and carbon content of 1.06% is used, the material is heated at 140 ° C for 12, 24 or 48 hours. The sorbents obtained are modified by adding them to a solution of tetraethylene pentamine and water in a weight ratio of 1: 10 and the suspension thus obtained is stirred for 6 hours and then dried for 2 hours at 80 ° C. Preferably, the adsorbent prior to use for CO2 sorption is soaked in inert gas at 100 ° C with a heating rate of 5 ° C / min. Nitrogen is used as inert gas. Preferably, the adsorbent is reused for CO2 sorption after desorption at 100 ° C for 1 hour.
