Gas purificn. - using graphite as catalyst support and energy recovery, while protecting catalyst from overheating

摘要

In (waste) gas purificn., graphite or a graphite mixt. of any morphology and shape is used as catalyst support and simultaneously as energy recovery material by simultaneous redn. of impurities from gas stream(s) and heat exchange and sepn. in cross, parallel or countercurrent flow through one or more reactors, in which the thermally conductive graphite protects the catalyst from over-heating and acts as catalyst. USE/ADVANTAGE - The fire resistance, thermal stability and conductivity of graphite make it suitable for simultaneous substance exchange and sepn. and as catalyst support.
