3D printing has emerged as an attractive way of formulating structured adsorbents, it imparts lower manufacturing costs compared to hydraulic extrusion while also allowing for unprecedented geometric control. However, binderless structures have not been fabricated by printing, ink formulation previously required clay binders which cannot be easily removed. In this study, we report the developme...

The study involved the removal of acidity from free fatty acid via esterification reaction oleic with ethanol. was done in a batch reactor using commercial 13X zeolite as catalyst. effects temperatures (40 to 70 °C) and time (up 120 minutes) were studied 6:1 mole ratio pure ethanol 5 wt. % results showed that removed increased increasing temperature time. Also, rises sharply during first period...

Abstract A way of harvesting water from the air that avoids discontinuity adsorption/desorption cycles is theoretically analyzed. rectangular prism-shaped adsorbent bed immersed in low-humidity air, at an angle to horizontal and subject a temperature gradient between two opposite open faces. The other four faces prism remain isolated. Water adsorbed on colder face, causing density surrounding p...

The current production of zeolites from natural sources requires high temperatures to achieve a phase change in the feedstock materials. Thermal processes such as calcination are energy-consuming and industry relies on fossil fuels generate necessary heat, which is neither sustainable nor environmental. This study presents for first time treatment aluminosilicate clay kaolin solar reactor produ...

The activation of soil-fixed phosphorus is a long-term concern in soil science. In order to enhance the activation effect to soil-fixed phosphorus in red soil, different modified zeolite, through physical, chemical method and the associated both physics and chemistry, was used in this paper. The results showed as following: 1) the activated ability to soil-fixed phosphorus in red soil for modif...
