Abstract

Afin d'améliorer leur aptitude à la combustion et leur pouvoir calorifique, les combustibles sont soumis à différents procédés de prétraitement. L'invention vise à améliorer la rentabilité du prétraitement des combustibles. À cet effet, les constituants gazeux non combustibles sont éliminés du combustible et amenés vers une autre utilisation dans un courant gazeux. En particulier, le courant gazeux est soumis à un procédé de séparation des gaz, permettant d'obtenir sous forme pure des composants gazeux séparés du combustible.
