A decade of ceria based solar thermochemical H2O/CO2 splitting cycle
( Elsevier Ltd , 2019 , Article)Since 2006, ceria is used as a redox reactive material for production of H2, CO, and syngas via a two-step solar driven thermochemical H2O/CO2 splitting cycle. Different forms of phase pure ceria were studied over a wide ... -
Application of Li-, Mg-, Ba-, Sr-, Ca-, and Sn-doped ceria for solar-driven thermochemical conversion of carbon dioxide
( Springer , 2020 , Article)The redox reactivity of the Li-, Mg-, Ca-, Sr-, Ba-, and Sn-doped ceria (Ce0.9A0.1O2−δ) toward thermochemical CO2 splitting is investigated. Proposed Ce0.9A0.1O2−δ materials are prepared via co-precipitation of the hydroxide ... -
Comprehensive performance analysis and optimization of 1,3-dimethylimidazolylium dimethylphosphate-water binary mixture for a single effect absorption refrigeration system
( Higher Education Press Limited Company , 2022 , Article)The energy and exergy analyses of the absorption refrigeration system (ARS) using H2O-[mmim][DMP] mixture were investigated for a wide range of temperature. The equilibrium Dühring (P-T-XIL) and enthalpy (h-T-XIL) of mixture ... -
Early gas kick detection in vertical wells via transient multiphase flow modelling: A review
( Elsevier B.V. , 2020 , Article Review)Gas influx from reservoir into the wellbore during drilling, tripping, or other operations, is a hazard. In the early stages, the influx may be nearly undetectable, but the kick can rapidly change from a seemingly steady ... -
Effectiveness of Ni incorporation in iron oxide crystal structure towards thermochemical CO2 splitting reaction
( Elsevier Ltd , 2017 , Article)In this study, Ni-doped iron oxide (NixFe3−xO4) materials were synthesized via the 1,2-epoxypropane assisted sol-gel method by varying the molar concentration of Ni from x=0.2 to 1. Sol-gel derived NixFe3−xO4 gels were ... -
