• Only 60 °C coupled with purge gas regenerates amine-based adsorbent by over 85%. Coupling TVSA is beneficial in terms of CO 2 productivity. can have lower specific energy requirement than closed TVSA. Using air and 100 during regeneration significantly decreases capacity. Mild temperature a viable direct capture process option. Comparison different options for (DAC) has usually been limited t...

The pollution of natural waters with aromatic amines originating from wastewaters of many industries is of serious concern due to its negative impact on environment and living organisms. In this research work, Cu–impregnated chitosan/alumina nanocomposite was prepared and employed as an adsorbent for removal of aromatic amines from water. The results showed that the adsorption capacity of the p...

Today, sulfur removal from fuels has improved by new adsorbents such as zeolites that needs extensive studies. This study investigates the feasibility of sulfur compounds adsorption on improved nano zeolite existing in organic fuels and desorption of them from nano-adsorbent.Some properties of improved nano zeolite were analyzed to receive better sulfur compounds adsorption.<e...

Abstract During sediment remediation, adsorbent addition is an effective technology for the removal of contaminants but cost often high. In this study, a low-cost adsorbent, ceramsite, made from contaminated riverbed was synthesized. The Fe-modified ceramsite (FMC) used as to remove arsenate aqueous solutions and reduce inorganic arsenic release sediments. Kinetic studies showed that chemisorpt...

Adsorptive treatment using granulated macroporous Al2O3-SiO2 adsorbent is proposed as a preliminary stage for residue pretreatment in refineries. The study evaluates the adsorptive of atmospheric and visbreaking at 485–510 °C 1 h−1 feed rate, resulting total liquid product yield about 73.0–75.0 wt%, coke on sorbent 12.6–18.3 demetallization exceeding 98%, reduction carbon 65–72%. paper also dis...

In this study, the adsorption of a multicomponent mixture active pharmaceutical compounds, such as Venlafaxine (VLX), Trazodone (TRZ) and Fluoxetine (FLX), was studied in biochar fixed-bed column. The selection appropriate (eucalyptus, grapevine cane holm tree biochar) an adsorbent carried out through batch assays. An insight into mechanism its correlation with chosen biochars performed, showin...
