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.

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.

Feb 23, 2022 In the present study, supercritical carbon dioxide (scCO2) was utilized as a waterless pulping for the isolation of cellulose nanocrystals (CNCs) from waste cotton cloths (WCCs). The isolation of CNCs from the scCO2-treated WCCs’ fiber was carried out using sulphuric acid hydrolysis. The morphological and physicochemical properties analyses showed …

Mar 20, 2022 Conventional extraction (CE) [19,20] is the most common. However, more sustainable, and efficient bioactive compounds extraction methods have been proposed, such as microwave-assisted extraction (MAE), supercritical-fluid extraction (SFE), subcritical-water extraction (SWE), and ultrasound-assisted extraction (UAE) [14,16,21].

Since the Industrial Revolution, anthropogenic carbon dioxide (CO2) emissions have grown exponentially, accumulating in the atmosphere and leading to global warming. According to the IPCC (IPCC Special Report, 2018), atmospheric warming should be 2 C to avoid the most serious consequences associated with climate change. This goal may be achieved in part by …

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 ...
