The filtration of coal derived gases at high temperatures and pressures (HTHP) affords the potential for increased efficiency from advanced power systems such as the British Coal gasification based 'Topping Cycle'. Rigid porous silicon carbide filters are amongst the most successful HTHP filters tested to date but questions about their long term durability remain unanswered. An alternative low density, high porosity fibrous ceramic filter medium has been developed and successfully tested on fuel gas at a filtration velocity of 0.1ms-1 and temperature of 950°C. Materials performance appeared adequate for this duty but longer duration tests will be required to confirm long term durability.
