- W3202059690 abstract "In this work, carbon dioxide adsorption-desorption characteristics were evaluated oncalcined raw dolomite, unsupported solvothermolysed dolomite and supportedsolvothermolysed dolomite. Solvothermolysis was employed to prepare theadsorbents by using three solvents, namely; ethanol, water and polyethylene glycol(PEG). Aluminium hydroxide wasintroduced as the support andthe variable studiedwas ratios of Al (OH)3to dolomite. Adsorbents were calcined at 400 °C, 800°C and1100 °C for 2 hours in air. Sample characterizationwas done using X-ray diffraction(XRD), N2 adsorption-desorption isotherms and thermogravimetric analysis (TGA).Solvothermolysis by ethanol as solvent produced the lowest average crystal size anddecomposed at the lowesttemperature (650°C) with the highest weight lost at 800°C(38%) compared to other samples at the same temperature. Solvothermolyseddolomite using ethanol with 1:2 molar ratio of Al(OH)3 to dolomite (1:2 t-e Al:dolomite) resulted in lowest average crystallite size among other supportedsolvothermolysed ratios. Calcination at 800°C leads to decomposition of dolomiteinto mixed oxides. The specific surface area increases with increasing calcinationtemperature up to 800°C. At 1100°C, the surface area slightly decreased a sign ofpossible sintering. The C02 adsorption desorption studies were performed by usingtemperature programmed desorption (TPD) and three isothermal adsorptiontemperatures were used; 100 °C, 200°C and 300°C respectively. At 100 °C theadsorption capacity of C02 is the highest for all samples compared to higheradsorption temperatures. The dolomite solvothermolysed and calcined at 800°C hasthe highest amount of C02 adsorbed at all temperatures. At 300°C, 1:2 t-e Al:dolomite has better adsorption capacity, about twice, than raw dolomite. This studysuccessfully discovered that solvothermolysis of dolomite using ethanol as thesolvent reduced the decomposition temperature of dolomite and produced anadsorbent with better porosity and high C02 adsorption capacity." @default.
