Abm'aet--The salient features that determine the possible use of a water vapour-zeolite 13X system as a method of energy storage were investigated. Cycling studies over two months revealed no decrease in water capacity nor any structural deterioration. The rate at which water could be desorbed in a static situation was determined at various temperatures from 110 to 250°C. The adsorption isother...

Silver doped zeolite (AgX) has attracted significant attention as a good adsorbent of organic iodine (CH3I) in the gas phase. Heat treatment waste, which is composed iodine-sorbed AgX, may be necessary for disposal, would removed from AgX at high temperature. Therefore, sorption and desorption behaviors CH3I on X (13X) were investigated. Herein, labeled by 125I tracer was synthesized via isotop...

Zeolite 13X molecular sieve with high sorption capacity and significant rate has been considered a promising candidate for seasonal heat storage. In this study, code is developed to simulate the adsorption process between zeolite water in all ranges of partial pressures, temperatures, sorbate loadings. The results from proposed were compared experiments good agreement was observed. After valida...

Oxygen is one of the most important products in chemical industries. This chemical element is used in various processes such as: refinery industries, manufacturing metal and other industrial operations. For instance, oxygen with high purity is utilized in different chemical processes like: steel construction, paper industries, wastewater treatment and glass production. In 1907, oxygen was produ...

The selective catalytic reduction (SCR) system in automobile using urea solution as a source of NH3 suffer from solid deposit problem pipe lines and poor efficiency during engine startup. Although direct use high pressure is restricted due to safety concern, which can be overcome by sorbents carrier. Strontium chloride (SrCl2) considered the best sorbent its sorption capacity; however, challeng...

Abstract In a way to overcome challenges with global warming, the use of fossil fuels in producing environmentally friendly energy towards reducing ozone layer depletion and greenhouse gas emissions by participating countries is interest. The adsorption refrigeration system has advantages long lifespan its environmental friendliness; however, major disadvantage low coefficient performance, whic...
