CO₂ RECOVERY AND DISPOSAL

Item #d93sep34

"Disposing of CO₂ from Fossil-Fueled Power Plants," J. Rose, Environ. Sci. Technol., pp. 1282-1283, July 1993. (Conference summary; see Global Climate Change Digest, p. 113, July-Aug 1993).

Item #d93sep35

Two items from Intl. J. Hydrogen Energy, 18(5), May 1993.

"Should We Store Carbon in Charcoal?" W. Seifritz (Inst. Energy Econ., Univ. Stuttgart (IER), Hessbrühlstr. 49a, D-7000 Stuttgart 80, Ger.), 405-407. Examines whether developed countries should pay developing countries to grow timber, and burn it to produce charcoal, then accept the charcoal for permanent storage. This procedure would sequester about half the carbon originally stored by the growing trees. Considers economical and political aspects.

"Technical Communication: On the Recycling of Carbon Dioxide from Flue Gases for the Catalytic Synthesis of Methanol with Exogenic Hydrogen," W. Seifritz (address immed. above), 439-440.

Item #d93sep36

"Partial and Total Reduction of CO₂ Emissions of Automobiles Using CO₂ Traps," W. Seifritz (addr. immed. above), ibid., 18(3), 243-251, Mar. 1993.

Proposes a new hybrid hydrogen/hydrocarbon-driven vehicle. It would use light metal hydrides and/or light metal carbides for energy storage; metallic atoms would not only carry fuel atoms, but, if discharged, would also carry the carbon dioxide from the burned hydrocarbons. The scheme would provide a way of collecting CO₂ for central disposal from a large number of diffuse sources (vehicles).

Item #d93sep37

"Disposal of Carbon Dioxide in Permeable Underground Layers: A Feasible Option?" B.C.W. van Engelenburg (Dept. Sci., Technol. & Soc., Univ. Utrecht, Padualaan 14, 3584 CH Utrecht, Neth.), K. Blok, Clim. Change, 23(1), 55-68, Jan. 1993.

Presents a preliminary feasibility study for disposal of recovered CO₂ in aquifers. The approach seems possible in light of existing geological knowledge, and could be done at an average cost of $1.40 per ton of CO₂ stored. However, considerable technical uncertainties remain.

Item #d93sep38

"Absorbing Carbon Dioxide," D. Bradley, Chem. in Britain, p. 180, Mar. 1993, summarizes and discusses research reported in the following two papers:

"Polyethyleneimine and Macrocyclic Polyamine Silica Gels Acting as Carbon Dioxide Absorbents," T. Tsuda (Dept. Synthetic Chem., Kyoto Univ., Yoshida, Kyoto 606-01, Japan), T. Fujiwara, J. Chem. Soc., Chem. Commun., p. 1659, 1992.

"Crystal Structure of...; a System which Readily Sequesters Carbon Dioxide from Air," S.C. Rawle (Dept. Chem., Univ. Warwick, Coventry CV4 7AL, UK), C.J. Harding et al., ibid., No. 23, 1701-1703, 1992.

Item #d93sep39

"Comments on the Role of Marine Sediment Burial as a Repository for Anthropogenic CO₂," R.A. Berner, Global Biogeochem. Cycles, 6(1), 1-2, Mar. 1992.
