Thermochemical treatment of fly ash for synthesis of mesoporous activated carbon
(
Springer Netherlands
, 2015 , Article)
A mesoporous activated carbon is produced from oil fly ash (OFA) using chemical and thermal treatments at different activation conditions. The ash samples were refluxed with a range of compositions of sulfuric, nitric, and ...
Investigation of the effect of polyelectrolyte structure and type on the electrokinetics and flocculation behavior of bentonite dispersions
(
Elsevier B.V.
, 2017 , Article)
The influence of surface charge type and density, and molecular weight of cationic, anionic and amphoteric polyacrylamide (PAM) on the electrokinetics, adsorption and flocculation behavior of highly stable bentonite ...
Heat duty, heat of absorption, sensible heat and heat of vaporization of 2–Amino–2–Methyl–1–Propanol (AMP), Piperazine (PZ) and Monoethanolamine (MEA) tri–solvent blend for carbon dioxide (CO2) capture
(
Elsevier Ltd
, 2017 , Article)
Chemical absorption using reactive amines for carbon dioxide (CO2) capture is characterized by absorption heat, heat of desorption and heat duty for regeneration (Qreg, kJ/mol CO2). This study experimentally investigated ...
Gelation of Emulsified Polyacrylamide/Polyethylenimine under High-Temperature, High-Salinity Conditions: Rheological Investigation
(
American Chemical Society
, 2018 , Article)
Emulsified gels are proposed as a method of water shut-off in oil and gas reservoirs and are designed to separate into a water phase and an oil phase under reservoir conditions. A first of its kind rheological study on the ...
Rheology of organoclay assisted extrusion of HDPE using Particle Image Velocimetry
(
Institution of Chemical Engineers
, 2015 , Article)
Wall slip is often seen as a source of flow enhancement and can play a significant role during certain melt instabilities in polymer processing. In the present investigation, the effect of organoclay on the wall slip of ...
An empirical determination of the whole-life cost of FO-based open-loop wastewater reclamation technologies
(
Elsevier Ltd
, 2019 , Article)
Over the past 5–10 years it has become apparent that the significant energy benefit provided by forward osmosis (FO) for desalination arises only when direct recovery of the permeate product from the solution used to ...
Synthesis and characterisation of Co2+-incorporated ZnO nanoparticles prepared through a sol-gel method
(
Elsevier B.V.
, 2016 , Article)
The properties of ZnO nanoparticles were modified by doping them with cobalt ions (Co2+) in various compositions through a sol-gel route. The Co2+-doped ZnO nanoparticles were characterised using X-ray diffraction (XRD), ...
CO2 sorption kinetics of scaled-up polyethylenimine-functionalized mesoporous silica sorbent
(
American Chemical Society
, 2015 , Article)
Two CO2 solid sorbents based on polyethylenimine, PEI (Mn ∼ 423 and 10K), impregnated into mesoporous silica (MPS) foam prepared in kilogram quantities via a scale-up process were synthesized and systematically characterized ...
Impact of combined oil-in-water emulsions and particulate suspensions on ceramic membrane fouling and permeability recovery
(
Elsevier B.V.
, 2019 , Article)
The application of crossflow ceramic microfiltration (CFCMF) to the removal of emulsified oil from a simple analogue of raw produced water (PW) arising from oil exploration has been studied. Outcomes relate to surfactant ...
Effects of sodium carbonate addition, heat and agitation on swelling and rheological behavior of Ca-bentonite colloidal dispersions
(
Elsevier Ltd
, 2017 , Article)
The effects of the addition of sodium carbonate (Na2CO3) and the subsequent simultaneous heating and stirring on the rheological behavior of Ca-bentonite colloidal dispersions have been investigated in this study. Ca-bentonite ...
