“…227 Interestingly, evidence suggests that consumers with a high level of technology and environmental engagement may be more attuned to both the safety risks and benets of domestic hydrogen. 47 Nevertheless, underlying risk perceptions 39,228,229 may prevent consumers from undertaking more in-depth safety evaluations, which threatens to constrain domestic hydrogen acceptance. Safety perceptions of gas-based and electric-powered cooking technologies may also diverge.…”

“…Continuous gas enhanced gas handling capacity and saved liquid absorbent consumption . For the other category of reactions with a low gas–liquid ratio, the gas was generally operated in a dispersed state for oxidation, chlorination, fluorination, and so forth, namely, gas-dispersed systems. The gas was frequently dispersed in a continuous liquid to enhance gas utilization efficiency .…”

Rotating packed bed (RPB) commonly generates tremendous centrifugal force to disperse the liquid phase and promote mass-transfer processes. However, plenty of chemical processes, such as oxidation and fluorination, featuring dispersed gas and continuous liquid, exist in the chemical industry. The gas-dispersed systems possessed low gas/liquid ratios, and the liquid residence time and operating mode of conventional RPBs cannot meet such reaction needs. Herein, a submerged RPB was developed for gas-dispersed systems. The stainless-steel wire mesh packing was immersed in liquid, while gas was dispersed and cocurrently flowed with liquid through the rotating packing. Hydrodynamic characteristics of the gas dispersion performance were then investigated by optical probe measurements. Results indicated that local gas holdup (0.85−5.42%) was proportionally correlated to the gas flow rate. Bubble size conformed to the log−normal distribution with a standard deviation in ranges of 0.59−1.17. With the elevation of rotational speed and diminishment of aeration rate, Sauter mean diameter of bubbles (d 32 , 1.49−5.51 mm) was decreased, and the average velocity of bubbles (v, 0.56−1.85 m/s) was increased. In a 0.05% ethanol−water solution, bubble coalescence probability could be reduced, and the bubble size was 20.2% smaller than that in water. Correlations to predict d 32 and v were established with deviations less than ±20 and ±15%, respectively.
