Microbubble enhanced mass transfer efficiency of CO₂ capture utilizing aqueous triethanolamine for enzymatic resorcinol carboxylation

Abstract

An inline method to investigate microbubble enhanced mass transfer and its effect on a model biocatalyst utilizing CO2 for carboxylation.

Novel procedure of CO2 capture of the CaO sorbent activator on the reaction of one-part alkali-activated slag

“…3 CO 2 capture is generally based on the use of a variety of sorbents, such as inorganic chemisorbents, MOFs, and organoamine adsorbents, which exhibited high theoretical uptake capacity, excellent catalytic performances, and generated valuable byproducts respectively. 4,5 In particular, CO 2 mineral sequestration deserves special attention as it is obtained directly. Du et al 6 found CO 2 has a strong affinity with montmorillonite, indicating a potential solution for CO 2 sequestration into a deep shale reservoir.…”

Microwave-Assisted Hydrogen-Free Reductive Deiodination of Iodoarenes with Silicon-Nanoarray Palladium-Nanoparticle Catalyst

“…In this study, we focused on triethanolamine (TEOA), which is a well-known sacrificial reductant for photocatalysis 7 10 and a CO 2 capture agent. 11 TEOA possesses synthetic and industrial advantages attributed to its low vapor pressure (1.3 Pa at 20 °C), high boiling point (335 °C), high flash point (199 °C), and low toxicity (orl-mus LD 50 = 5846 mg/kg). 12…”

“…At present, numerous efforts are being made to develop reductive dehalogenation systems for green sustainable chemistry. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Heterogeneous 1 and homogeneous 2 Pd, Zr, 3 Fe, 4 Cu, 5 and Ni 6 catalysts, Ru 7 and organic 8 photocatalysts, as well as nonmetallic agents 9 have been applied in these dehalogenation systems in the presence of reducing agents. Due to the increasing demand for a hydrogen society, reactions using hydrogen gas has garnered attention, promoting the development of dehalogenation systems using hydrogen gas.…”

Internal Optimization for Enhancing the Microbubble Dispersion Characteristics of a Stirred Tank

“…Wu et al found that microbubble decomposition of pollutants including phenol and nitrobenzene is markedly more efficient than conventional bubbling in terms of ozone consumption across a broad pH range . Similarly, it was found that this highly efficient aeration technique has the potential to reduce the necessary CO 2 gas feed as well as the waste of unreacted CO 2 in the biocatalytic reaction . Most of these studies were carried out in bubble columns up to date.…”
