ABSTRACT:

This paper investigates a chemical method among CO(sub 2) fixation technologies. The chemical fixation of CO(sub 2) is basically reduction.  It is well known that useful chemical intermediates such as methanol, ethanol, low-grade hydrocarbon, etc. can be synthesized from CO(sub 2) by catalytic hydrogenation. A large amount of energy is required for chemical separation of oxygen from CO(sub 2). In the future methanol synthesis from CO(sub 2) instead of CO is also expected to be commercialized. CO(sub 2) reduction to hydrocarbon requires more hydrogen than CO reduction (Ficher-Tropsch method) but development of its new process hereafter will make fixation of a great deal of CO(sub 2) possible. Various studies are made on electrochemical, photochemical and photosynthetical CO(sub 2) reduction to hydrocarbon and on CO(sub 2) reduction to methane by anaerobic bacteria. For chemical fixation and utilization of CO(sub 2), it is needed not only to develop elemental technologies, but to make a comprehensive consideration of volume, exergy, environment and economy. 327 refs., 75 figs., 68 tabs.
