Title
(EN) REFORMING PROCESS FOR SYNTHESIS GAS PRODUCTION AND RELATED PLANT
(FR) PROCEDE DE REFORMAGE DESTINE A LA PRODUCTION D’UN GAZ DE SYNTHESE ET INSTALLATION CORRESPONDANTE
Abstract
(EN)
A reforming process for synthesis gas (12) production from a mixture of hydrocarbons (14) comprises a first step, or pre-reforming step, in which a process mixture 18), comprising said mixture of hydrocarbons :i4: and steam (16), is subjected to a preliminary catalytic conversion reaction, obtaining a partial conversion product (22) comprising hydrogen, carbon oxides and hydrocarbons, and a second step, or main reforming step, in which said partial conversion product (22) is subjected to a conversion completion reaction, obtaining said synthesis gas (12), said pre-reforming step being carried out in pseudo- isothermal conditions.
(FR)
Le procédé de reformage selon l’invention, destiné à la production d’un gaz de synthèse (12) à partir d'un mélange d’hydrocarbures (14), comprend une première étape, ou étape de pré-reformage, au cours de laquelle un mélange du procédé (18), comprenant ledit mélange d’hydrocarbures (14) et de la vapeur (16), est soumis à une réaction de conversion catalytique préliminaire, donnant un produit de conversion partielle (22) comprenant de l'hydrogène, des oxydes de carbone et des hydrocarbures, et une seconde étape, ou étape principale de reformage, au cours de laquelle ledit produit de conversion partielle (22) est soumis à une réaction de conversion totale, donnant ledit gaz de synthèse (12), ladite étape de pré-reformage étant réalisée dans des conditions pseudo-isothermes.
