Title: Solidified oil fuel
IPC: C10L7/02
Filed: 1922-07-12
Abstract: 206,889. Illemann, R. July 12, 1922. Composition fuel.-Peat containing three times its weight of water, or peat together with water, is ground and agitated so as to break up the fibres in the presence of oil, or greases &c. reduced to a liquid state, in greater proportion than the amount of dry peat, so that the mass when subsequently dried has over 50 per cent and may have up to 75 per cent of oil. The oil becomes emulsified and combines with the broken fibres forming a homogeneous mass, which under continued agitation becomes stiff and is then moulded by extrusion or otherwise into briquettes &c. To expedite drying the mass may be heated during agitation and before moulding. In an example 16 oz. of black wet peat were agitated with 4 oz. of crude mineral oil and formed a briquette containing 3 oz. of dry peat and 4 oz. of oil.
