The present disclosure relates to a process plant and a process for production of a hydrogen rich gas, comprising the steps of (a) directing an amount of a synthesis gas comprising at least 15%, 50% or 80% on dry basis of CO and Hin combination, a gas comprising steam, and a recycled intermediate product gas to be combined into a first reactor feed gas, (b) directing said first reactor feed gas to contact a first material catalytically active in water gas shift reaction, producing an intermediate product gas, (c) splitting said intermediate product gas in the recycled intermediate product gas and a remaining intermediate product gas, (d) combining said remaining intermediate product gas with a further amount of synthesis gas forming a second reactor feed gas, (e) directing said second reactor feed gas to contact a second material catalytically active in the water gas shift reaction, producing a product gas, characterized in the HO:CO ratio in said first reactor feed gas being from 0.5 to 2.0 and the HO:CO ratio in said second reactor feed gas being from 0.5 to 2.0. with the associated benefit of distributing the heat development and thus reducing the maximum temperature in the reactors by limiting the extent of reaction of the reacting mixture, and thereby reducing the amount of steam required for limiting methanation.

Method for production of a hydrogen rich gas

Process for the production of synthesis gas by catalytic steam reforming of a hydrocarbon containing feedstock in parallel in an autothermal steam reformer and heat exchange reformer, the heat for the steam reforming reactions in the heat exchange reformer being provided by indirect heat exchange with the combined effluent of the heat exchange reformer and a portion of the autothermal steam reformer.

Process for producing synthesis gas

The invention relates to a process for the production of liquid hydrocarbons by Fischer-Tropsch synthesis in which the reforming section of the plant comprises a process line comprising autothermal reforming (ATR) () or catalytic partial oxidation (CPO), and a separate process line comprising steam methane reforming (SMR) ().

Process for the production of synthesis gas

A process for the catalytic removal of hydrogen cyanide, formic acid and formic acid derivatives from synthesis gas comprising these compounds, carbon monoxide and hydrogen, the process comprising contacting the synthesis gas with a catalyst comprising one or more metals selected from the group consisting of silver, gold, copper, palladium, platinum and their mixtures and supported on a carrier comprising at least one of the oxides of scandium, yttrium, lanthanum, cerium, titanium, zirconium, aluminum, zinc, chromium and molybdenum.

Process for the removal of hydrogen cyanide and formic acid from synthesis gas

Process and system for the production of synthesis gas from a hydrocarbon feed stock comprising the steps of endothermic and/or adiabatic catalytic steam reforming and autothermal steam reforming in series, wherein the steam reforming is carried out in one or more endothermic stages in series or in one or more adiabatic steam reforming stages in series with intermediate heating of feed stock gas leaving the adiabatic reforming stages and wherein carbon monoxide containing gas characterised by having a molar ratio of hydrogen to carbon of less than 4.5 is added prior to at least one of the endothermic or adiabatic steam reforming stages and/or prior to the autothermal steam reforming step.
