Abstract
Official abstract text for this publication.
The present invention relates to a method for producing hydrogen, with reduced carbon dioxide emissions, from a hydrocarbon mixture. In said method, the hydrocarbon mixture is reformed so as to produce a synthetic gas that is cooled, then treated in a shift reactor so as to be enriched with H2 and CO2. Optionally dried, said mixture is treated in a PSA hydrogen purification unit in order to produce hydrogen. The residue is treated by means of partial condensation with a view to capturing CO4 before said residue is sent as fuel to reforming.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for the production of hydrogen in combination with capture of carbon dioxide starting from a mixture of hydrocarbons, the process comprising the steps of: (a) reforming the mixture of hydrocarbons in a reformer in order to obtain a crude synthesis gas comprising hydrogen, carbon monoxide, carbon dioxide, methane, water vapor and impurities; (b) cooling the crude synthesis gas with recovery of the available heat; (c) reacting all or part of the…
