NOVELTY - The process comprises generating a hot raw synthesis gas (4), cooling the synthesis gas for producing a cold gas at temperature T6, enriching hydrogen in the cold synthesis gas by conversion of carbon monoxide (water gas shift) to obtain a synthesis gas enriched of hydrogen at a temperature T84, rapidly cooling the hydrogen enriched synthesis gas to produce a cold gas at a temperature T104, and separating hydrogen from the cold hydrogen enriched synthesis gas by pressure modulation adsorption to obtain hydrogen and residual gas.    USE - The process is useful for production of hydrogen from hydrocarbides such as natural gas or fossil fuels obtained by vapor reforming, auto-thermal reforming or partial oxidation.    ADVANTAGE - The process ensures automatic, economical, easy and rapid production of hydrogen from hydrocarbides in a systematic manner with increased pressure and temperature and less consumption of energy using a pressure swing adsorption unit.    DETAILED DESCRIPTION - The process comprises generating a hot raw synthesis gas (4), cooling the synthesis gas for producing a cold gas at temperature T6, enriching hydrogen in the cold synthesis gas by conversion of carbon monoxide (water gas shift) to obtain a synthesis gas enriched of hydrogen at a temperature T84, rapidly cooling the hydrogen enriched synthesis gas to produce a cold gas at a temperature T104, and separating hydrogen from the cold hydrogen enriched synthesis gas by pressure modulation adsorption to obtain hydrogen and residual gas. The rapid cooling of the synthesis gas is produced in a thermokinetic compressor, which simultaneously cools and compresses the synthesis gas for producing cold hydrogen enriched synthesis gas at a temperature T104 and a pressure P104 using a cold liquid such as water. The conversion of carbon monoxide is a step of shift at an average temperature of 350-550 degrees C, where the enriched synthesis gas has a temperature of 410-600 degrees C. An INDEPENDENT CLAIM is included for an installation for the production of hydrogen gas.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a process for production of hydrogen.
