Emulsifying residual oil with water - for use as fuel in gas turbine, giving clean, efficient combustion

In the processing of residual oil for use in gas turbines, esp. in jet transmission appts. in aircraft or ships, 3-8 (5) wt.% of water is added to the residual oil, an oil-water emulsion is formed in which the water droplets are dispersed in a continuous oil phase and the emulsion is led to a gas turbine for combustion. Cheap residual oils can be utilised. Overheating of the jet appts. is avoided. The emulsion is stable and can be stored for a relatively long time without sepn. In the gas turbine chamber the water droplets undergo 'micro-explosion' into steam, leading to formation of fuel droplets of 25 mu, compared with 70150 mu in known processes. Complete, clean combustion is achieved in the short combustion chamber of the gas turbine. Addn. of water leads to a water gas reaction during combustion, increasing the combustion efficiency, and also lowers the peak temp. in the combustion chamber.

Bio-fuel composition and method for manufacture of bio-fuel composition

The production of power from a carbonaceous fuel and methanol

Carbonaceous fuel is oxidised to form carbon monoxide and hydrogen, which is then catalytically shifted to produce hydrogen and carbon dioxide for combustion in the generation of power. Methanol is cracked using the heat of the shift reaction to produce more hydrogen and carbon monoxide, which optionally may be subject to a shift reaction, to provide additional fuel to meet peaks in the demand for power. The heat evolved by the shift reaction may be transferred to a methanol cracking vessel using a thermal fluid for indirect heat transfer or a methanol cracking vessel may be embedded in the shift catalyst bed. In a further alternative the methanol may be cracked over the shift catalyst bed.
