Solar hydrogen production via thermochemical metal oxide - Metal sulfate water splitting cycle
(
AIChE
, 2015 , Conference Paper)
This paper reports the thermodynamic analysis of solar H2 production via two-step thermochemical iron oxide - iron Sulfate (IO-IS) water splitting cycle. The first step belongs to the exothermic oxidation of FeO via SO2 ...
Laundry wastewater treatment using ultrafiltration under different operating conditions
(
American Institute of Physics Inc.
, 2018 , Conference Paper)
The laundry wastewater of one of the hospitals in Qatar was selected and studied. It was found that hospital laundry is releasing considerable amount of wastewater i.e. 1800 - 2500 liters/cycle while washing 40 - 50 kg of ...
Solution combustion synthesis of active catalysts for hydrogen production from ethanol
(
AIChE
, 2014 , Conference Paper)
Solution combustion synthesis method was used to synthesize Cu and Ni based catalysts active for hydrogen production from ethanol decomposition reaction. The catalyst synthesis parameters (such as fuel to oxidizer ratio, ...
Synthesis and characterization of novel Ni-B-Y2O3 composite coatings
(
AIChE
, 2014 , Conference Paper)
Corrosion damages and the importance of its prevention has been presented. An overview of previous research on Ni-B (and Ni-P) coatings has been presented. Synthesis and characterization of electrodeposited Ni-B and Ni-B-Y2O3 ...
Integrating ethics into the chemical engineering curriculum: The Qatar University experience
(2013 , Conference Paper)
Qatar is growing at an unprecedented rate due to the utilization of its vast gas reserves. The country's wealth stems from oil, gas and petrochemical industries. Engineers are in high demand in all specializations and Qatar ...
Solar thermochemical conversion of CO2 into synthetic fuels via ferrite based redox reactions
(
AIChE
, 2014 , Conference Paper)
In this contribution, we report the synthesis NiFe2O4 and CoFe2O4 redox materials via sol-gel method. For the synthesis of these materials via sol-gel approach, the Ni, Co, and Fe precursors were first dissolved in ethanol ...
Solar thermochemical splitting of H2O and CO2 using nonvolatile metal oxides
(
AIChE
, 2017 , Conference Paper)
In this study, a Co ferrite/ZrO2 ceramic nanornixture was synthesized by the propylene-oxide-assisted sol-gel method. Cobalt, iron, and zirconium nitrate salts were used as the metal precursors, and ethanol and propylene ...
