An increase in the coal rank gradually to a maximum level of around 11%–12% vitrinite reflectance for good coking coals and decreases the coking potential as the rank increases, and beyond 16% reflectance drops sharply, making it practically noncaking beyond a reflectance of 18%
Results show that low CSR regime has a higher mean size It was also observed that change in coking properties of individual coal in a coal blend significantly affects the coke quality Key Words Coal blend properties, operating parameters, recovery stamp charge coke making, coke CSR, Coke AMS

Mar 09, 2015· Within the area of carbon based refractories, phenol-formaldehyde (Phenolic) resins have found a multitude of us One significant attribute of phenolic resins is their ability to form a carbon bond This, to a large extent, contributed to their initial use in this Industry, as cleaner alternatives to the traditional pitch and tar binders
The electrolyte was not fully dense due to the moderate sintering temperature adopted (700 °C)Though many pinholes are observed but they are isolated with each other It should be noted that Chen et al 40 claimed that higher temperature or longer sintering time helps to reach the full densification of a similar composite electrolyte
