A process for the production of at least one of amorphous carbon or graphite, preferably of carbon black, from atmospheric air, biogas or flue gas CO2 is given, including at least the following steps: a) isolation of concentrated CO2 of a concentration of at least 50% v/v from atmospheric air, green house air or flue gas preferably by means of a cyclic adsorption/desorption process on amine-functionalized adsorbents; b) conversion of said captured CO2 into a gaseous or liquid saturated or unsaturated hydrocarbon by hydrogenation: c) cracking of said saturated or unsaturated hydrocarbon to at least one of amorphous carbon or graphite, preferably carbon black, wherein the H2 resulting from step c) is at least partially used in the hydrogenation of step b).

Methods for the removal of CO2 from atmospheric air or other CO2-containing gas in order to achieve CO2 emissions reductions or negative CO2 emissions

A process for the production of synthetically produced methane ()/gaseous and/or liquid hydrocarbons (). For this purpose, hydrogen () from an electrolytic arrangement () which is operated by means of regeneratively generated electric energy and carbon dioxide () are synthesized in a methane synthesis (FIGS.-) or Fischer-Tropsch synthesis (FIGS.-) or other suitable hydrocarbon synthesis, the carbon dioxide () being produced from an air/gas flow () by means of a carbon dioxide recovery system (FIG.). The carbon dioxide () is obtained from the air/gas flow () in the carbon dioxide recovery system (FIG.) by way of a reversible adsorption process. Also a production system () for the production of synthetically produced methane/gaseous and/or liquid hydrocarbons (), in particular for carrying out the production process according to the invention, comprising an electrolytic arrangement () which is operated by means of regeneratively generated electric energy () for producing hydrogen (), a carbon dioxide recovery system (FIG.) for producing carbon dioxide () from an air/gas flow () and a methane (FIG.) or Fischer-Tropsch synthesis (FIG.) or any other suitable hydrocarbon synthesis for synthesizing hydrogen () and carbon dioxide () to methane ()/gaseous and/or liquid hydrocarbons ().

Production process and production system for producing methane / gaseous and/or liquid hydrocarbons

A method for separating gaseous carbon dioxide from a mixture by cyclic adsorption/desorption using a unit containing an adsorber structure with sorbent material, wherein the method comprises the following steps: (a) contacting said mixture with the sorbent material to allow said gaseous carbon dioxide to adsorb under ambient conditions; (b) evacuating said unit to a pressure in the range of 20-400 mbarand heating said sorbent material to a temperature in the range of 80-130&#xb0; C.; and (c) re-pressurization of the unit to ambient atmospheric pressure conditions and actively cooling the sorbent material to a temperature larger or equal to ambient temperature; wherein in step (b) steam is injected into the unit to flow-through and contact the sorbent material under saturated steam conditions, and wherein the molar ratio of steam that is injected to the gaseous carbon dioxide released is less than 20:1.
