Abstract

The emission of carbon dioxide into the atmosphere from the fossil fuels is considered as major sources of the greenhouse effect. Capture with solid sorbents followed by underground storage is one of the most appealing options to reduce of CO2 emission. Zeolites are microporous, crystalline materials with well-defined structures. Due to highly porous and consistent matrix, aluminosilicate are a potential material for CO2 capture. In this study commercial zeolite 13X was treated with gaseous ammonia at different temperatures from 200 to 700°C. 1 g of zeolite was placed in a ceramic boat and put into tube furnace. The sample was heated in argon flow. When the furnace reached the desired temperature, the atmosphere was changed from argon to ammonia and then held for 2h. After this time the sample was cooled down to 100 °C. Finally the flow was switched to argon. Under this atmosphere the furnace reached room temperature. The samples were characterized by powder X-ray diffraction, X-ray photoelectron spectroscopy and nitrogen adsorption-desorption isotherm measurements at 77 K. CO2 uptake was evaluated by isotherm measurement carried out at 298 K and pressure up to 0.95 atm. The modified with ammonia samples indicated improvement of CO2 adsorption capacity. The CO2 uptake was the largest for ammonia treated sample at 600 °C.
