Design of an energy conversion system with decomposition of H ₂ O and CO ₂ using ferrites

Abstract

The energy conversion system was designed in order to reduce the green-house effect and to get energy resources by decomposition of CO 2 and H 2 O. This system is consisted of two parts, one is CO 2 decomposition with the reduced ferrite by H 2 and the other is H 2 O decomposition with reduced ferrite by CH 4 . CH 4 could be synthesized in this system by methanation reaction using carbon, which was deposited on the ferrite surface in the CO 2 decomposition process. Also, CH 4 was used as reducing gas to reduce the ferrite for H 2 O decomposition. H 2 O was decomposed by oxidation of oxygen-deficient ferrite. In this energy conversion system, the reduced Cu-ferrite easily decomposed CO 2 and H 2 O into the useful gases such as CO and H 2 , respectively. Cu-ferrite is a suitable material to apply to this system because it showed excellent redox reactivity on the energy conversions.

Summary report : direct approaches for recycling carbon dioxide into synthetic fuel.

“…As in the work of the Tamaura group, the ferrites were activated by H 2 reduction. A second group in Korea has investigated the use of reduced Cu-ferrites for decomposing CO 2 [40,41]. There are two interesting twists to this work.…”

Environmentally Friendly and Hostile Water and Aqueous Solutions

“…Seeking to overcome these issues, similar two-step cycles favor gas-solid separations and/or lower temperatures. Recent investigations have focused on cycles using modified ferrites (substituted with Co, Ni, or Mn) or ceria-based materials as the oxidation-reduction media for dissociation of H2O to yield H2(S. , Hiroshi Kaneko et al, 2007, H.

Research Trend on Nuclear Energy From 2008 to 2018: A Bibliometric Analysis

“…The phenomenon of global warming made researchers to propose a model for the generation of liquid hydrocarbon fuel, derived from CO 2 emissions (Shin et al, 2004), using a process that separates oxygen and water from carbon dioxide. Thus, Graves et al proposes a system with an efficiency of 70% where the cost of generating electricity with gasoline varies depending on the location of the study (Graves et al, 2011).…”
