Catalytic and non catalytic solvent regeneration during absorption-based CO2 capture with single and blended reactive amine solvents
TL;DR: In this paper, the authors used molecular potential energy surface diagrams of the deprotonation of a protonated amine (AmineH + ) in combination with ion speciation plots of the vapour liquid equilibrium (VLE) model to provide a better understanding of the drastic reduction of energy required for CO 2 stripping from some amine solutions under certain operating conditions.

TL;DR: In this paper, a series of bifunctional Al2O3/HZSM-5 catalysts (Al-ZSM) were prepared by the combined precipitation ultrasound method and used for the CO2 desorption process.

Investigation of CO2 Regeneration in Single and Blended Amine Solvents with and without Catalyst
TL;DR: In this paper, three types of catalysts (H-ZSM-5, MCM-41 and SO42-/ZrO2) were studied to determine the respective roles of catalyst and solvent in heat duty and CO2 desorption rate with an initial CO2 loading of 0.5 mol CO2/mol amine at 371 K.

Synthesis of C-doped TiO2 by sol-microwave method for photocatalytic conversion of glycerol to value-added chemicals under visible light
TL;DR: In this paper, a C-doped TiO2 photocatalyst was synthesized using a one-step sol-microwave method with micro-crystalline cellulose as the carbon source to achieve the desirable visible light absorption, cluster size, surface area and band gap.

TL;DR: In this article, the authors investigated the carbon dioxide (CO2) equilibrium solubility of seven novel tertiary amines, which include 1-(2-Hydroxyethyl)pyrrolidine (1-(2)-HE)PRLD), 4-((2-hydroxyethyl)(ethyl)amino)-2-butanol (HEEAB), 3-diethylamino-1,2-propanediol (DE-1-2-PD), 4-(dipropylamino)- 2-Butanol (DPAB), 1-(
