Frontiers Methanol Production via CO2 Hydrogenation ...

Carbon dioxide (CO2) is one of greenhouse gases, which can cause global warming. One of studies to mitigate CO2 emissions to the atmosphere is to convert CO2 to valuable products (i.e., methanol). To make methanol production via CO2 hydrogenation a competitive process, the optimal operating conditions with minimum production cost need to be considered.

CO 2-enhanced coalbed methane (CO 2-ECBM) recovery has a significant impact on CO 2 sequestration and unconventional gas extraction, which will contribute to long-term safety production and alleviation of global warming. CO 2 injected into the deep coal reservoir is converted into a supercritical state (ScCO 2), which has a complex physical or chemical …

Feb 19, 2022 Supercritical CO 2 (SC–CO 2) extraction is used not only for the synthesis of adsorbent but also for template removal. The main advantage of this method is the adjustable physical and chemical properties including density, viscosity, diffusivity, and mass transfer by changing the operating pressure and temperature.

Shale oil extraction - Wikipedia

Shale oil extraction - Wikipedia

Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution.The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities.. Shale oil extraction is usually …

Supercritical CO 2 mostly serves as an extraction solvent because it is nontoxic, noninflammable, inexpensive, and readily available, and it does not cause formation of inhibitory compounds. In supercritical CO 2 explosion, the explosive release of CO 2 pressure disrupts the cellulose and hemicellulose fractions, and consequently increases the ...
