英文要約Title : Development of Technologies for Coal Utilization Using Chemical Looping Combustion with CO2 Separation (FY2015-FY2017) FY2015 Annual Report

  This technology development project is carried out for the aim of the selection of the oxygen carrier and the construction of the chemical looping coal combustion (CLC) system to get the CO2 separation cost that is less than 1000yen/CO2-ton. We are carrying out four following items in this project.
1. The selection of the oxygen carrier and the production method
2. The performance evaluation of selected carriers
3. The optimization of the system operating condition and the structure of the facility
4. The investments of the technology trend and the economy of business
  We selected six type oxygen carriers which are three artificial carriers and three types of Ilmenite as the natural carrier. And we have made apparatuses for the performance evaluation of carriers and have studied the measurement procedures for several apparatuses. In addition, we are planning to make the three reactor CLC test apparatus to get the performance data on long time operation. Before designing this facility, we made three fluidized bed cold model and took data of the minimum fluidized velocity, the cohesiveness, the circulation flow rate about Ilmenite carrier. We have designed three reactor CLC test apparatus using these data and started work to build it.
  On the flip side, the study of system condition is carried out using Aspen process analysis tool. We got the reaction rate coefficients using the calculation model considering the reaction rate of the coal and the oxygen career. And we are carrying to optimize the conceptual design of CLC which was done in 2015. We reconsidered the oxygen career size and redesign reactor under the comment on the working group, thereby we could reduce to about half of the cross section of the former design. We are struggling the mixture of the particle with the specific density difference using the cold model and the DEM-CFD simulation. The first result is gotten by these studies and we have the prospect that different specific density particles can mix.
  For the investigation of the technology trend, we attended the network meeting of IEAGHG and got the information. For the economy of business, we researched the situation of CO2-EOR in U.S. and the development program of CO2-EOR in Indonesia and Vietnam. Moreover we researched the utilization of by-product nitrogen for the production of the shale gas.
