The invention relates to a process for producing porous CaO-based spheres modified with carbon nanotubes for capturing CO2. The invention also relates to the spheres produced and to the use thereof for capturing CO2 generated by a vehicle internal combustion engine, aiming to reduce the quantity of CO2 released into the atmosphere. L'invention concerne le procédé d'obtention de sphères poreuses à base de CaO modifiées avec des nanotubes de carbone pour la capture de CO2. L'invention concerne également les sphères obtenues et leur utilisation pour la capture de CO2 produit par un moteur à combustion interne de véhicule, visant à réduire la quantité de CO2 émis dans l'atmosphère. A invenção refere-se ao processo de obtenção de esferas porosas a base de CaO modificadas com nanotubos de carbono para a captura de CO2. A invenção se refere ainda às esferas obtidas e ao seu uso para captura de CO2 gerado por um motor de combustão interna veicular, visando reduzir a quantidade de CO2 lançado na atmosfera.
