چکیده
|
In this paper, the development of a new potassium carbonateon alumina support sorbent prepared byimpregnating k2co3 with an industrial grade of al2o3 support was investigated. the co2 capturecapacity was measured using real flue gas with 8% co2 and 12% h2o in a fixed-bed reactor at atemperature of 65 °c using breakthrough curves. the developed sorbent showed an adsorptioncapacity of 66.2 mgco2/(gr sorbent). the stability of sorbent capture capacity was higher than thereference sorbent. the so2 impurity decreased sorbent capacity about 10%. the free carbon had asmall effect on sorbent capacity after 5 cycles. after 5 cycles of adsorption and regeneration, thechanges in the pore volume and surface area were 0.020 cm3/gr and 5.5 m2/gr respectively. smallchanges occurred in the pore size distribution and surface area of sorbent after 5 cycles.
