Journal ArticleDOI
Solubility of Oxygen in Organic Solvents and Calculation of the Hansen Solubility Parameters of Oxygen
TL;DR: In this paper, the Hansen solubility parameters (HSPs) of oxygen were determined from the measured solubilities in the pure solvents, where the HSPs of oxygen are δd = 6.7 MPa1/2, δp = 0.944 kPa, and δh = 3.8 MPa 1/2.
Journal ArticleDOI
Evaluation of advanced oxidation processes (AOP) using O3, UV, and TiO2 for the degradation of phenol in water
TL;DR: In this paper, a compact AOP reactor that generates ozone by UV irradiation was developed, and the ozone was generated using the Chapman method, i.e., by irradiating oxygen with UV light; the use of this method saves energy.
Journal ArticleDOI
Preparation and CO2 adsorption properties of aminopropyl-functionalized mesoporous silica microspheres
TL;DR: The particle size, Brunauer-Emmet-Teller (BET) specific surface area, and mesoporous regularity decreased with increasing APTES content, and it was confirmed that the spherical shape and the mesostructure were maintained even if 20mol.% ofAPTES was added to the silica source.
Journal ArticleDOI
Synthesis, characterization and gas permeation properties of a silica membrane prepared by high-pressure chemical vapor deposition
TL;DR: In this paper, cylindrical silica membranes with dead-end structure were prepared by an extended counter-diffusion chemical vapor deposition (CVD) method, in which a tetramethylorthosilicate (TMOS) silica source was fed from the outside of a cylinrical membrane support with γ-alumina interlayer.
Journal ArticleDOI
Comparison of Hansen Solubility Parameter of Asphaltenes Extracted from Bitumen Produced in Different Geographical Regions
TL;DR: In this paper, the Hansen solubility parameters (HSPs) of asphaltenes extracted from oil sand bitumen samples produced at Athabasca in Canada and also from a vacuum residue fraction (VR) produced in the Middle East were determined.
