Abstract

A reactor arrangement and method for thermal activation of a mineral to increase porosity by flash volatilisation of gas from the mineral, comprising: a flash calciner reactor having a reaction chamber and a heating chamber separated by a reactor wall, the reaction chamber and the heating chamber being in heat transfer communication through the reactor wall; a reaction feed comprising the mineral in particulate form entrained in steam passing through the reaction chamber; a heating fluid flow passing through the heating chamber in counterflow to the reaction feed passing through the reaction chamber; whereby the thermal activation of the mineral proceeds by flash volatilisation of gases from the mineral in the reaction feed by means of heat transferred through reactor wall from the counterflow of heating fluid the chamber to the reaction feed, so that temperature of the mineral feed increases to reach a maximum temperature at exhaust of thermally activated mineral from the reactor.
