Preparation of ZnO-MWCNTS nanocomposite: structural features and applications for enhanced oil recovery 06-Nov-2019 Since last few decades, the importance of tertiary oil recovery is increasing day by day. Quest for novel hydrophobic materials compatible to oil for enhanced recovery using electromagnetic is the major focus in this field. In the present study, we present ZnO-MWCNT nanocomposite prepared using sol-gel technique for the application of enhanced oil recovery. XRD analysis shows that average particle size in the range of 30-39 nm. Morphology analysis showed that ZnO are coated on the surface of the MWCNT. Vibrational analysis indicated that ZnO-MWCNT nanocomposite exhibited E2 (high) mode of ZnO and G (sp2 carbon) bands of MWCNTs and intense sharp peak of Zn-O stretching bond. A 11.11% of oil recovery was observed using ZnO-MWCNT composite nanofluid. This recovery further enhanced to 16.10% under the effect of electromagnetic field. Therefore, this novel material can be used to enhance oil recovery with application of EM waves. [Received: September 7, 2017; Accepted: March 28, 2018]
MWCNT for ambient urea synthesis 15-Sep-2018 Highlights • Effect of adsorption of reactant gases on orbital energy states of CNT • Effect of strength of magnetic field on the urea yield using CNT nanocatalyst • Simultaneous effect of flow rate, magnetic field strength and duration of reaction . Engtangled MWCNT were synthesized using substrate free floating catalyst chemical vapor deposition technique . MWCNT synthesized had hematite and magnetite encapsulated inside, two clear XRD peaks show the presence of non aligned CNT • The maximum urea yield (using optimization) was accomplished by applying 1.25 T of magnetic field and using 0.25 L/min of flow rate for a reaction time of one minute. • Using lower flow rate and high magnetic field strength improved urea yield.
CO2 Mixture Adsorption at Single-Walled Carbon Nanotube: Effects from Different Gases and Stoichiometric Ratios 01-Jun-2018 Using adsorption locator for the most stable adsorption site searches, the authors investigated adsorption of mixture of gases with different carbon dioxide mole ratio at a single-walled carbon nanotube (SWCNT). A total of six mixtures were investigated, two mixtures consist of hydrogen, nitrogen and carbon dioxide with compositions 3:1:1 and 3:1:2. Whereas the reaming four mixtures consist of ammonia and carbon dioxide with compositions 5:1, 4:1, 3:1 and 3:2. Results demonstrated that gas interactions with carbon nanotubes increased as the mole ratio of carbon dioxide increased in H2, N2 and CO2 mixture, conversely decreased for NH3 and CO2 mixture. After increasing CO2 mole fraction from 1/5 to 1/3 for hydrogen, nitrogen and carbon dioxide mixture, adsorption energy and rate on carbon nanotube atoms increased by 45 and 33%, respectively, due to a 59% increase in van der Waal interactions. The preferred molar ratio of H2, N2 and CO2 mixture for adsorption is 3:1:2. The maximum adsorption energy and rate for NH3 and CO2 mixture is obtained using the 5:1 sample. Adsorption energy for the NH3 and CO2 mixtures increased by 18% when the ratio changed from 3:1 to 3:2 while the adsorption rate decreased considerably.
Green urea synthesis catalyzed by hematite nanowires in magnetic field 15-Apr-2017 Highlights Catalytic activity of hematite nanocatalyst enhanced by changing the surface magnetic moment. Catalytic activity of hematite nanowires is better than nanoparticles. Activation energy of hematite nanowires is lower than nanoparticles. CO2 has significant role to produce urea.
