Abstract: The present invention provides a process of producing hydrogen comprising introducing methane and/or other light hydrocarbons into a reaction chamber and reacting said gases in said reaction chamber in a bed of solid carbonaceous materials to give hydrogen, wherein said carbonaceous materials are macro-structured carbonaceous materials, wherein the porosity of the carbonaceous material is in the range of 30 to 70 vol.-% and the carbonaceous material contains a content of carbon of 99 wt.-% to 100 wt.-% and a content of alkaline-earth metals, transition metals and metalloids of 0 and 1 wt.-% in relation to the total mass of the solid carbonaceous material, wherein the iron content is between 0 and 0.5 wt.-%, the magnesium content is between 0 and 0.005 wt.-%, the manganese content is between 0 and 0.01 wt.-%, the silicon content is between 0 and 0.01 wt.-% and the nickel content is between 0 and 0.025 wt.-%. In addition, the present invention provides the use of said carbonaceous materials as carrier material in bed reactors.

Abstract: A method for producing carbon monoxide comprises allowing carbon-providing particles to flow downwardly under gravity flow as a particle bed through a reaction zone; heating the particles in the reaction zone to a temperature of at least 800 °C; feeding a feed gas stream comprising carbon dioxide through the reaction zone in counter current to the particles flow, whereby carbon-depleted particles are obtained; withdrawing the carbon-depleted particles from the reaction zone; and withdrawing a product gas stream comprising carbon monoxide from the reaction zone. The process allows for improved heat integration.
