Abstract

A reactor (20) and a process for upgrading solid materials, such as coal, having low thermal conductivity are disclosed. The reactor includes an outer shell (10) that defines an internal volume for retaining a packed bed of solid materials to be treated and a plurality of plates (12a to 12h) of a thermally conductive material positioned within the internal volume. Each plate includes one or more passageways (14a to 14h) through which a heat transfer fluid can flow. In use, each plate defines one or more thermally conductive bypass or bypasses between the heat transfer fluid and the solid materials in the region of the plate so that in use substantially all of the solids are heated or cooled to a desired temperature range by heat exchange between the heat transfer fluid and the solids via the plates.
