Another object of the present invention is to provide a process for the direct production of valuable chemicals through capture and conversion of CO.sub.2.

A system may include a chamber with a main sub-chamber and a first porous membrane separating a first sub-chamber from the main sub-chamber. The system may include a fluid in the chamber and an input directing inflow into main sub-chamber proximate an entry end of the chamber. The system may include a first output permitting outflow from the first sub-chamber proximate an exit end of the chamber wherein a molecule entering at the entry end must traverse a length of the chamber to exit at the exit end.

A system and a method for continuously separating carbon dioxide from gas mixtures, utilizing a continuous loop of porous monoliths which support a sorbent within its pores. Continuously exposing a portion of the continuous loop of monoliths to a flow of gas mixture containing a minor proportion of carbon dioxide, to adsorb carbon dioxide from the flow. The loop passes through a sealed regeneration and carbon dioxide capture assembly located astride a portion of the loop, and which is capable of sealingly containing a monolith in relative movement through the assembly. The assembly chamber comprises a plurality of separately sealed zones, including at least one zone for purging oxygen from the monoliths, -a subsequent zone for heating the monolith to release the adsorbed carbon dioxide, and another cooling zone for cooling the monolith prior to reentering the adsorption portion of the loop where it is exposed to oxygen.

A blast furnace facility includes a process for capturing and sequestering CO2 generated from the facility process, producing hydrogen from the hot blast furnace gas, and using blast furnace gas as methanol feed. The CO2 rich streams from the facility may be sent to sequestration of some form via a sequestration compressor, thereby reducing the overall emissions from the facility. The other products generated by the facility are used as methanol feedstock and to produce hydrogen.
