Miike coal

The relationship between conversion and C% in coal (d.a.f.) is shown in Fig.3. In this figure, the relatively close relationship between conversion and C% in coal is observed, but at the same time, it is found also that there are some exceptions in this relationship. The behaviour of abnormal coals could possibly be explained by the inert content in the coal at the same carbon level. That is, in Yamakawa s data, the inert content of Miike and Yubari coals are lower, while Griffin coal is higher. [Pg.96]

Moreover, in coals of a similar carbon level, such as Miike coal, Newdell coal, and Grose valley coal, the reactivity of coal decreases greatly with the increasing inert content of coal. [Pg.96]

The relationship between conversion and the mean maximum reflectance is shown in Fig.7 In Yamakawa s data, a fairly good relationship is found except for abnormal coals of high inert content (Griffin, Grose valley) and low inert content (Miike). A similar good relationship is also found in P.H. Given s data. However, the characteristics of this relationship are the reverse in both cases. Thus, it seems that the mean... [Pg.97]

Five coal materials were used in this study. These were Miike, Taiheiyo, Hikishima (Japanese coals), Morwell (Australian) and Bukit Asam (Indonesian) coals. The proximate and ultimate analyses of these coals are shown in Table 1. All of catalysts were powdered before... [Pg.212]

In this study the oil yield decreased with reaction time, as oil was polymerized at higher temperature for Miike, Taiheiyo and Hikishima coals. Thus the kinetic models (Case 2 or 3) which involve two steps of resini-fication and coking correlated data reasonably well for above coals, whereas for Morwell and Bukit Asam coals, Case 5 is more suitable. [Pg.223]

The temperature dependency of the rate constants on Miike coal was determined between 350 C and 450 C. The result is shown in Table 4. [Pg.223]
