CO2 RECOVERY AND DISPOSAL
"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).
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
"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.
"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
"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.
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.
"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.
