Development of teawaste based bio-sorbent materials for removal of Cr(VI) from wastewater
… of hexavalent chromium by MBTW was a spontaneous endothermic reaction. <br/><br/>In order to study the effects of process conditions during the production of the MBTW, effect of temperature and duration of the treatment were investigated. The MBTW-(2, 4 and 6) was heating at 450℃ for 2, 4 and 6 …

Exploration of the Endothermic and Exothermic Reactions of Calcium Oxide and Magnesium Oxide and Design of a Vessel for a Thermochemical Heat Storage System
… involved in the TES system is a thermochemical reaction involving metal oxides such the calcium oxide (CaO) or magnesium oxide (MgO) and water. In the output mode, an exothermic reaction is initiated when liquid water or steam is injected into the metal oxide particle bed to produce Ca(OH)2 or …

Evaluation of Various Energy Storage Options for the Internal Thermal Loads of a Non-Airbreathing Hypersonic Vehicle
… Additionally, the use of energy-consuming endothermic reactions is considered. An innovative PCM-endothermic reaction hybrid approach is also developed. Both thermodynamic and transient/quasi-stationary models are developed for each of these proposed heat sink technologies. Prototypes are …

A study of differential thermal analysis utilizing statistical experimental design
… were analyzed to determine the area under the endothermic reaction peaks as measured by Cr-Al differential thermocouples. It was found that densities and rates both yielded highly significant values and that the interactions of the two showed significant results when examined by a distribution …

Kinetics and transport phenomena in the chemical decomposition of copper oxychloride in the thermochemical Cu-CI Cycle
… for hydrogen production includes three chemical reactions of hydrolysis, decomposition and electrolysis. The decomposition of copper oxychloride establishes the high-temperature limit of the cycle. Between 430 and 530 oC, copper oxychloride (Cu2OCl2) decomposes to produce a molten salt of copper …

A Lagrangian, Discontinuous-Galerkin Material Response Solver for the Analysis of Ablative Thermal Protection Systems
… in which the elevated temperatures trigger an endothermic reaction that decomposes the material into char and gases, and through thermochemical ablation, in which char and pyrolysis gases blow away from the surface. Their use is common in high-velocity hypersonic missions through dense …
