Abstract
The increased emission of carbon dioxide (CO2) derived from the use of fossil fuels has a major in fluence on global warming and climate change. In order to reduce these emissions, carbon dioxide can be capture from the air and converted into useful products. This can be done for example using the Sabatier reaction, in which CO2 and hydrogen (H2) are converted into methane (CH4) and water (H2O). This reaction is reversible and it is therefore desirable to adsorb the water to shift the reaction equilibrium to the product side, applying Le Chatelier’s principle. Water adsorption is achieved using zeolites, which are hydrated minerals with an open crystal structure. There are many zeolite types, both natural and artificial. This study will focus on determining which zeolite type is the most suitable for water adsorption in the Sabatier reaction at relevant process circumstances and which properties account for this superior performance.
