Kinetic analysis of an anion exchange absorbent for CO2 capture from ambient air
This study reports a preparation method of a new moisture swing sorbent for CO2 capture from air. The new sorbent components include ion exchange resin (IER) and polyvinyl chloride (PVC) as a binder. The IER can absorb CO2 when surrounding is dry and release CO2 when surrounding is wet. The manuscript presents the studies of membrane structure, kinetic model of absorption process, performance o...
متن کاملRegeneration of Spent Acid from Chehical Processes
The demand for S A R plants is on the rise. this. First and foremost, the requirements for dealing with spent acids in an environmentally safe manner and the shift toward a refinery alkylation process to avoid the possible hazards from hydrogen fluoride. "tolling" or transporting spent acid long distances to independent regeneration plants for recycling is hazardous and may be cost prohibitive....
متن کاملDirect electrochemical regeneration of monooxygenase subunits for biocatalytic asymmetric epoxidation.
We report the first example of direct electrochemical regeneration of a flavin-dependent monooxygenase for asymmetric epoxidation catalysis. It is shown that electrochemical regeneration of the oxygenase subunit of the multicomponent styrene monooxygenase is sufficient to perform enantiospecific S-epoxidation of various styrene derivatives. Kinetic bottlenecks of the novel electroenzymatic reac...
متن کاملCharacterization of spent AA household alkaline batteries.
The aim of this work is identification of the structural components of actual domestic spent alkaline AA batteries, as well as quantification of some of their characteristics. Weight, humidity, ash content, zinc and zinc oxide on anode, manganese on cathode and other metals, potassium hydroxide on the internal components and heating values for papers, anode and cathode were determined in severa...
متن کاملOptimization of chemical regeneration procedures of spent activated carbon
The chemical regeneration of granular activated carbon exhausted in a petrochemical wastewater unit was investigated. Gas chromatography and energy-dispersive X-ray spectroscopy demonstrated that spent activated carbon carries large types of organic and inorganic materials. Diverse chemical solvents were adopted in comparison with traditional chemical solvents and regeneration efficiency was in...
