Methanol from atmospheric carbon dioxide: A liquid zero emission fuel for the future

Tri-reforming of methane: a novel concept for catalytic production of industrially useful synthesis gas with desired H2/CO ratios

“…Flue gases from fossil fuel-based electricity-generating units are the major concentrated CO 2 sources in the US. If CO 2 is to be separated, as much as 100 MW of a typical 500-MW coalfired power plant would be necessary for today's CO 2 capture processes based on the alkanolamines [4][5][6]. Therefore, it would be highly desirable if the flue gas mixtures can be used for CO 2 conversion but without preseparation of CO 2 .…”

“…In general, CO 2 can be separated, recovered and purified from concentrated CO 2 sources by two or more steps based on either absorption or adsorption or membrane separation. Even the recovery of CO 2 from concentrated sources requires substantial energy input [4,5]. According to US DOE, current CO 2 separation processes alone require significant amount of energy which reduces a power plant's net electricity output by as much as 20% [4,6].…”

RETRACTED ARTICLE: An overview of CO2 electroreduction into hydrocarbons and liquid fuels on nanostructured copper catalysts

“…Electrochemistry is an important enabling technology because this involves converting electrical energy to chemical energy. In one study, CO 2 reacted with electrolytic hydrogen to produce methanol and water (14)(15)(16), while in another concept, methane was produced when CO 2 reacted with electrolytic hydrogen (with condensation of water to shift the equilibrium and achieve good yields) (17). However, direct electrochemical reduction of CO 2 to hydrocarbons would be more efficient, simpler and time saving.…”
