Abstract

L'invention a trait à une technique de gazéification sous haute pression faisant intervenir du métal liquide réparti en deux zones. Le but de cette technique est de convertir des alimentations hydrocarbonées, à l'état solide, liquide ou gazeux, en courants distincts riches en hydrogène et en monoxyde de carbone, sous une pression d'une valeur comprise entre 2 et 200 atmosphères, et ce, par un apport d'hydrocarbures dans une première zone de fonte liquide (4) à l'intérieur de laquelle se forme un gaz riche en hydrogène puis, par la mise en circulation de cette fonte liquide de manière à la faire entrer en contact avec un gaz contenant de l'oxygène, ceci dans une seconde zone (5) à l'intérieur de laquelle se forme un gaz riche en monoxyde de carbone. Au-dessus de 0,3 % en poids, la concentration en carbone dans le courant de fonte liquide est stabilisée de manière à réduire au maximum la formation d'oxyde ferreux (FeO). L'hydrogène sulfuré et d'autres composés volatils soufrés sont également extraits, par épuration dans un équipement en aval (12 et 16), des courants gazeux distincts.
