‘Dry bases’: carbon dioxide capture using alkaline dry water

Abstract

An alkaline form of ‘dry water’—a ‘dry base’—is prepared by the high-speed mixing of aqueous solutions of metal carbonates or organic amines with hydrophobic silica nanoparticles.

CO2capture by dry alkanolamines and an efficient microwave regeneration process

“…These ndings were previously outlined in our patent led in May 2013, 26 prior to the work being reported by Dawson et al We refer to this DA as DA f . In contrast to the ndings by Dawson et al, 25 we found that DA f showed excellent recyclability and stability. Studies were conducted on monoethanolamine (MEA) and diethanolamine (DEA) due to their widespread industrial usage.…”

“…The per-uorinated silica particles can also be recycled and re-used to prepare DA f with a negligible change in their wettability and overall quality for at least three cycles. Moreover, as suggested by the recent work of Dawson et al, 25 the amine component of the DA f is also isolated by the silica particles from pipelines and other corrosion sensitive materials, leading to further reduction in maintenance costs associated with the addition of corrosion inhibitors and repair of damage to pipelines. Last but not least, this novel method of using DA f is not restricted to MEA and DEA; in principle any dry liquid can be formed provided that nanoparticles of appropriate surface energy are selected.…”

Validation on Carbon Dioxide Hydrate Formation Through Analysis on the Solubility of Co2 in Water Using Henry’s Law and the Experimental Pressure-Time Curve

“…Silica gel was initially dried inside the oven for one night at 200 o C. Dry silica gel (0.5 g) was placed inside blender and water was added in excess (19 times the mass of dry silica gel) so that the total mass of the mixture was 50 g. The silica gel and water mixture were vigorously stirred at the speed of 37000 rpm [30,31] for 90 seconds using a high-speed blender. Then, the mixture was left at atmospheric condition until the final mass reached equilibrium.…”

One‐Step Synthesis of Multifunctional Zinc‐Iron‐Oxide Hybrid Carbon Nanowires by Chemical Fusion for Supercapacitors and Interfacial Water Marbles

“…The special soft matters formed from the multi‐dimensional interfacial interactions between complex materials with different surface tensions have revealed significant application potential in micro‐scale mass transport, control release and gas storage, such as liquid marble, colloidosome, and dry water . Besides the synthesis of soft matters, their manipulations at the tiny scale are also important and various techniques and platforms have been developed for the stimuli‐responsive transport, mixing, and shaping of liquid droplets .…”
