NOVELTY - The process for production of hydrogen combined with carbon dioxide capture from a mixture of hydrocarbons, comprises reforming a mixture of hydrocarbons for obtaining a synthesis gas (3) containing hydrogen, carbon monoxide, carbon dioxide, methane, water vapor and impurities, cooling the synthesis gas with heat recovery, performing a shift reaction for all or part of the synthesis gas to oxidize carbon monoxide into carbon dioxide in the presence of water, and cooling the synthesis gas enriched in hydrogen and carbon dioxide and separating the condensed water.    USE - The process is useful for the production of hydrogen combined with carbon dioxide capture from a mixture of hydrocarbons, where the hydrogen is useful as a clean fuel (claimed).    ADVANTAGE - The process is capable of energy efficiently and economically producing the hydrogen with creating any environmental problems.    DETAILED DESCRIPTION - The process for production of hydrogen combined with carbon dioxide capture from a mixture of hydrocarbons, comprises reforming a mixture of hydrocarbons for obtaining a synthesis gas (3) containing hydrogen, carbon monoxide, carbon dioxide, methane, water vapor and impurities, cooling the synthesis gas with heat recovery, performing a shift reaction for all or part of the synthesis gas to oxidize carbon monoxide into carbon dioxide in the presence of water, cooling the synthesis gas enriched in hydrogen and carbon dioxide and separating the condensed water, separating the constituents of synthesis gas in a dry adsorption unit by pressure modulation to obtain a high pressure stream enriched in hydrogen and Rpsa flow waste gas containing mainly carbon dioxide, hydrogen, carbon monoxide, methane and impurities, and performing secondary shift reaction to eliminate the water for producing a dry gas depleted in carbon monoxide and enriched in carbon dioxide and hydrogen. The Rpsa flow waste gas is compressed under pressure of 20-100 bars. The second shift reaction is carried out by supplying the compressed Rpsa flow waste gas and residuals, and then the shifted gas is treated for separating carbon dioxide to produce a hydrogen-rich gas, which is recycled as a clean fuel. The shift gas undergoes pressure swing adsorption by modulation of carbon dioxide and hydrogen-rich waste gas. An INDEPENDENT CLAIM is included for an installation for producing hydrogen with carbon dioxide from a mixture of hydrocarbons.
