Tar Produced in the Coking of Rammed Batch

Abstract

The yield of tar and its properties in the coking of rammed batch is of particular interest in the light of the broader adoption of this technology. In laboratory reactors, the tar yield from rammed batch is lower than for unrammed batch. However, in industrial furnaces, the tar obtained in the coking of rammed batch is characterized by lower levels of pyrolysis. It is evident from analysis of the tar’s quality, viscosity, and group composition and also from granulometric analysis of the quinoline-insoluble components that the primary destruction products of the thermochemical processes in the coking of rammed batch react with the solid and liquid phases.
