Solid fuel production from cattle manure by dewatering using liquefied dimethyl ether

The lower heating value (LHV) of DME dewatered manure under these conditions increased to 13.8 MJ/kg, which was 18.1 times that of original cattle manure. The cattle manure dewatered by DME had a lower self-ignition risk than thermally dried cattle manure because of the extraction of crude fat by DME. Therefore, it could be more efficiently produced and safely used as a biomass fuel following DME dewatering.
