Poster's note : does CO2-to-fuel tech count as geoengineering? Not sure but it's fairly interesting. Good way of using some spare sunshine...

Olah* and G. K. Surya Prakash**[email protected].*[email protected]. Loker Hydrocarbon Research Institute and Department of Chemistry, University of Southern California, University Park, Los Angeles, California 90089-1661, United States Journal of the American Chemical SocietyVol. 138: Issue. 3: Pages. 778-781 Publication Date (Web): December 29, 2015 DOI: 10.1021/jacs.5b12354 A highly efficient homogeneous catalyst system for the production of CH3OH from CO2 using pentaethylenehexamine and Ru-Macho-BH (1) at 125–165 °C in an ethereal solvent has been developed (initial turnover frequency = 70 h–1 at 145 °C). Ease of separation of CH3OH is demonstrated by simple distillation from the reaction mixture. The robustness of the catalytic system was shown by recycling the catalyst over five runs without significant loss of activity (turnover number > 2000). Various sources of CO2 can be used for this reaction including air, despite its low CO2 concentration (400 ppm). For the first time, we have demonstrated that CO2captured from air can be directly converted to CH3OH in 79% yield using a homogeneous catalytic system. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
