“Non-adhesion grain boundaries” are formed when low-quality coal grains do not adhere to other grains in the carbonization process because of the low dilation of coke. To better understand the effects of non-adhesion grain boundaries on coke stre

Autor: Atul Sharma, Yuuki Mochizuki, Hideyuki Hayashizaki, Naoto Tsubouchi, Ryo Naganuma, Takahiro Shishido
Publikováno v: Tetsu-to-Hagane. 107:15-23
In order to produce high-strength coke from low-quality coals, noncovalent bonds between O-functional groups in coal were cleaved by pyridine containing HPC pyridine soluble and HPC-derived thermoplastic components were introduced into the pores form

Autor: Yuuki Mochizuki, Takahiro Shishido, Ryo Naganuma, Naoto Tsubouchi, Hideyuki Hayashizaki
Publikováno v: ISIJ International. 59:1427-1436
In this work, we studies the production of higher-strength coke from chemically-loaded coal in which noncovalent-bonds between O-functional groups in coal are cleaved by pyridine and HPC-derived thermoplastic components are introduced into the pores

Numerical Investigation of the Effect of Inert Components on the Shrinkage Phenomenon of Coke
Autor: Yohsuke Matsushita, Seiji Nomura, Hideyuki Hayashizaki, Shohei Matsuo, Hideyuki Aoki, Yasuhiro Saito
Publikováno v: ISIJ International. 59(8):1495-1505
The effect of inert components in coke on the shrinkage ratio of coke was numerically investigated. The carbonization process of semi-coke was simulated by using the finite element method. Coke models with a coke matrix, pores, cracks, and/or inert c

Effects of Hydrocarbon Addition on Increase in Dilatation of Coal
Autor: Yasuhiro Saito, Koji Kanehashi, Kazuya Uebo, Hideyuki Hayashizaki, Hideyuki Aoki, Yohsuke Matsushita, Seiji Nomura
Publikováno v: ISIJ International. 59(8):1404-1412
The addition of coal tar pitch mainly composed of polycyclic aromatic hydrocarbons (PAHs), increases the dilatation of coal. We investigated the effect of PAHs on the maximum dilatation (MD) of hard coking coals and semi-soft coking coals. Twenty-six
