Even for coke beds with similar void fractions, the averaged-coke-shape factors such as φ and (φD)2 give little clear correlation for holdup sites. Instead of averaged-coke-shape information, only the direct evaluation of the void shape of the packed bed can explicitly trace the holdup site.日本鉄鋼協会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/76152https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/76152/1/ISIJ%20Int.%2058%289%29_%201742-1744%20%282018%29.pdf0915-15591347-5460AA10680712ISIJ International589174217442018-09-15enginfo:doi/10.2355/isijinternational.ISIJINT-2018-369著作権は日本鉄鋼協会にあるpublisher
