PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). In brief, the Fe–Mn–K catalyst shows a CO 2 conversion of 38.2%

China team develops efficient multifunctional catalyst for conversion of CO2 to gasoline-range hydrocarbons

Green Car Congress

Qingjie Ge at the Dalian Institute of Chemical Physics in China has developed an efficient, stable, and multifunctional Na-Fe 3 O 4 /HZSM-5 catalyst for the direct production of gasoline-range hydrocarbons from CO 2 hydrogenation. The gasoline-range isoparaffins and aromatics are selectively formed and finally diffuse out of zeolite pores.

Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Recent research in electrocatalytic CO 2 conversion points the way to using CO 2 as a feedstock and renewable electricity as an energy supply for the synthesis of different types of fuel and value-added chemicals such as ethylene, ethanol, and propane. Their paper is published in Proceedings of the National Academy of Sciences (PNAS).

U of I study: synthetic fuels via CO2 conversion and FT not currently economically & environmentally competitive

Green Car Congress

However, they noted, that with the right combination of high FT fuel yield and low electricity and hydrogen price, the synthetic fuel system could produce fuels at a cost range similar to the reference year 2014 petroleum-based fuel prices. The well-to-gate energy efficiency varies from 41 to 65%. Stubbins, and Paul J. 6b00665.
