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%

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The most compact form of captured carbon is through its transformation to solid carbon.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The facility will filter 4,000 metric tons of carbon dioxide from the air and mineralize it underground. With direct air capture technology, carbon dioxide is extracted from the ambient air and air free of CO 2 is returned to the atmosphere. The carbon dioxide is thus permanently removed from the atmosphere.

NRL researchers optimizing two-step process for synthesis of jet-fuel-range hydrocarbons from CO2

Green Car Congress

Researchers at the US Naval Research Laboratory (NRL) are investigating an optimized two-step process for the synthesis of liquid hydrocarbons in the jet fuel range from CO 2 and hydrogen. Carbon dioxide is also hydrogenated directly to methane, in a widely cited thermodynamically favorable and highly competitive side reaction.
