  • study on a lab scale hydrogen production by Closed Cycle thermo chemical iodine sulfur process
    International Journal of Hydrogen Energy, 2010
    Co-Authors: Ping Zhang, Songzhe Chen, Laijun Wang, T.y. Yao
    Abstract:

    Abstract The Iodine–Sulfur (IS) thermo-chemical process for the production of hydrogen is one of the most promising approaches for use of the high temperature process heat supplied by high temperature reactor, which was developed in the Institute of nuclear and new energy technology (INET) of Tsinghua University, China, and INET initiated the fundamental studies on IS Cycle since 2005. Based on the experiment results obtained by fundamental researches, a lab-scaled Closed Cycle loop (IS-10), which featured in electro-electrodialysis (EED) for hydriodic acid (HI) concentration, was designed and built at INET. The loop was composed of three sections, i.e., Bunsen section, HI section and sulfuric acid section. The Closed Cycle experiment on the loop was successfully carried out recently. In HI section, HI x produced by Bunsen reaction was continuously purified through reverse Bunsen reaction, concentrated by EED, and then HI solution was obtained by distillation. Finally HI was catalytically decomposed to H 2 and I 2 with the conversion of 20%. In sulfuric acid section, sulfuric acid was continuously purified, concentrated by distillation, and catalytically decomposed to SO 2 , O 2 and H 2 O with the conversion of 75%. In Bunsen section, water, including reCycled water, reacted with I 2 and SO 2 reCycled from HI section and sulfuric acid section to form two separated acids phases, thus to form a Closed Cycle. The Closed Cycle experiment lasted for 7 h with the hydrogen production rate of 10 NL/h, with Pt loaded on activated carbon and copper chromite used as the catalysts for HI and sulfuric acid decomposition, respectively. This paper summarizes the main features of IS-10 and the main results of the Closed Cycle experiment. So far IS-10 is the second reported facility on which Closed experiment was carried out, and the first one with EED embedded to perform a Closed Cycle operation.

  • Closed-Cycle gas turbine for power generation: A state-of-the-art review
    Fuel, 2016
    Co-Authors: Olumide Olumayegun, Meihong Wang, Greg Kelsall
    Abstract:

    In the last few years, there has been considerable interest in Closed-Cycle gas turbine power plants due to the important contribution it can make to meeting worldwide energy demands. Closed-Cycle gas turbine has the potential to serve as power conversion system for a wide range of energy sources such as fossil fuel, concentrated solar power, nuclear, biomass and waste heat. However, there is a need to provide an update on the development of Closed-Cycle gas turbine with a view to identifying the challenges and the opportunities for future commercialisation. This paper is a review of the research activities and studies carried out worldwide so far on Closed-Cycle gas turbine. The historical development in chronological order was presented first, followed by a review of some fundamental features such as heat sources, working fluids, heat exchangers and Cycle layouts/configurations. Important research programmes and experimental/pilot plants as well as previous commercially operated plants were also reviewed. Moreover, various studies based on modelling and simulation of Closed-Cycle gas turbine were reviewed, in addition to the operation and control strategies. Based on the review studies, the challenges ahead and potential future breakthroughs were highlighted in different aspects such as heat source technologies, power conversion system and demonstration plant.
