Gas-phase mass-transfer measurements in a falling-film microreactor

Review of carbon capture absorbents for CO2utilization

“…However, the majority of the studies conducted were focused on academic endeavours such as absorption mechanisms and system performance rather than on CO 2 capture. 102,103 NaOH has an excellent CO 2 absorption capacity which is higher than that of MEA absorbent. Yoo et al 104 stated that the theoretical absorption capacity of NaOH is 1.11 tons CO 2 /ton NaOH while MEA is approximately 0.72 tons CO 2 /ton MEA.…”

“…The usage of NaOH for CO 2 absorption has been studied intensively for the past 80 years. However, the majority of the studies conducted were focused on academic endeavours such as absorption mechanisms and system performance rather than on CO 2 capture 102,103 . NaOH has an excellent CO 2 absorption capacity which is higher than that of MEA absorbent.…”

Generation of Ethynyl‐Grignard Reagent in a Falling Film Microreactor: An Expeditious Flow Synthesis of Propargylic Alcohols and Analogues

“…To our delight, when the flow rate of EtMgBr decreased to 0.1 or 0.05 mL min −1 , an excellent selectivity of up to 99/1 was obtained (Table 2, entries 4 and 5). A calculation using THF as liquid phase indicated that the thickness of the falling films corresponding to the flow rates of 0.2, 0.1 and 0.05 mL min −1 were 30, 24 and 19 μm, and the residence times were 13.6, 21.6 and 34.3 s, respectively (Table 2, entries 2–4) 17. Accordingly, we deduced that the modification of these parameters in terms of the flow rate of EtMgBr was responsible for the better gas‐liquid contact and mass transfer, thereby facilitating the gas‐liquid reaction and improving the selectivity.…”
