Study of Methane Storage and Adsorption Equilibria in Multi-Walled Carbon Nanotubes [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2008
Adsorbed natural gas has various advantages and is relatively more economical than liquefaction and compression. Carbon nanotubes can be introduced as a new candidate for natural gas storage.

Adsorption of Organic Chemicals in Soils [PDF]

open access: yesEnvironmental Health Perspectives, 1989
This paper presents a review on adsorption of organic chemicals on soils sediments and their constituents. The first part of this review deals with adsorption from gas and liquid phases and gives a discussion on the physical meaning of the shape of adsorption isotherms.

Catalytic Oxidation of Thiophenes with Air and PW/SBA-15

open access: yesAdsorption Science & Technology, 2007
Catalytic oxidation is considered a viable method for reducing the sulphur level of transportation fuels and H 2 O 2 is usually used as the oxidant. For this reason, it is essential that any extraction operation must remove the oxidation product from the

Experimental Studies of the Generalized Adsorption Isotherm for the Supercritical Region

open access: yesAdsorption Science & Technology, 2001
Some problems arise with the characteristic curve proposed by the Dubinin–Polanyi potential theory when this is applied to supercritical adsorption although, as an alternative, the generalized isotherm is capable of well modelling isotherms for different

Efficient degradation and mineralization of diclofenac in water on ZnMe (Me: Al; Co; Ga) layered double hydroxides and derived mixed oxides as novel photocatalysts

open access: yesComptes Rendus. Chimie, 2022
The removal of diclofenac (DCF) from aqueous solutions was attempted using photocatalytic processes, involving a series of novel photocatalysts based on ZnMe (Me: Al; Co; Ga) layered double hydroxides (LDHs) and their derived mixed oxides.

The effect of surfactant concentration, salinity, temperature, and pH on surfactant adsorption for chemical enhanced oil recovery: a review

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Enhanced oil recovery (EOR) processes have a great potential to maximize oil recovery factor of the existing reservoirs, where a significant volume of the unrecovered oil after conventional methods is targeted.

Impact of oxygen vacancies in Ni supported mixed oxide catalysts on anisole hydrodeoxygenation

open access: yesCatalysis Communications, 2022
The hydrodeoxygenation (HDO) activity of anisole has been investigated over Ni catalysts on mixed metal oxide supports containing NbZr and TiZr in 1:1 and 1:4 ratios. XRD patterns indicate the incorporation of Ti (or Nb) into the ZrO2 framework.
