主　　题：CO_(2) utilization survey energy balances synthesis-gas green houses micro-algae fossil fuel recovery 

摘      要：If substantial amounts of CO_(2),which according to actual scenarios may in the future be captured from industrial processes and power generation,shall be utilized effectively,scalable energy efficient technologies will be ***,a survey was performed to assess a large variety of applications utilizing CO_(2) chemically(e.g.,production of synthesis-gas,methanol synthesis),biologically(e.g.,CO_(2) as fertilizer in green houses,production of algae),or physically(enhancement of fossil fuel recovery,use as refrigerant).For each of the processes,material and energy balances were set *** with pure CO_(2) at standard conditions,expenditure for transport and further process specific treatment were *** on these calculations,the avoidance of greenhouse gas emissions by applying the discussed technologies was *** on the currently available technologies,applications for enhanced fossil fuel recovery turn out to be most attractive regarding the potential of utilizing large quantities of CO_(2)(total capacity1000 Gt CO_(2))and producing significant amounts of marketable products on one hand and having good energy and material balances on the other hand(t_(CO_(2)-emitted)/t_(CO_(2)-utilized)0.34).Biological processes such as CO_(2) fixation using microalgae look attractive as long as energy and CO_(2) balance are ***,the development of effective photobioreactors for growing algae with low requirements for footprint area is a challenge.
