  • Patent number: 5551956
    Abstract: A superheavy oil emulsion fuel having a low viscosity and a good long-term stability, which comprises, in a mixed and emulsified state, 100 parts by weight of a superheavy oil, 25 to 80 parts by weight of water and 0.02 to 5 parts by weight of a specific nonionic surfactant.A method for regenerating an oil-in-water superheavy oil emulsion fuel deteriorated to such a slight extent that the emulsion fuel can be pumped and handled as a fluid liquid to give an oil-in-water superheavy oil emulsion fuel having a good fluidity and a low unburned content, and a method for regenerating an oil-in-water superheavy oil emulsion fuel deteriorated to such a remarkable extent that the emulsion fuel has such a high viscosity that the pumping thereof is difficult and cannot be handled as a fluid liquid to give an oil-in-water superheavy oil emulsion fuel having a good fluidity and a low unburned content, wherein use is made of a specific nonionic surfactant.

  • Patent number: 5024676
    Abstract: A super-heavy oil emulsion fuel is formed by emulsification using 100 parts by weight of super-heavy oil, 30-80 parts by weight of water, 0.01-4 parts by weight of an anionic surface activating agent, and a nonionic surface activating agent having an HLB (hydrophilic lipophilic balance) of 9-19 at an anionic surface activating agent/nonionic surface activating agent weight ratio of 1/99-75/25. The super-heavy oil emulsion fuel can also comprise 100 parts by weight of super-heavy oil, 30-80 parts by weight of water, 0.05-4 parts by weight of a nonionic surface active agent having an HLB of 9-19 and, optionally, 0.005-4 parts by weight of an anionic surface active agent.

  • Patent number: 4251345
    Abstract: A method of liquefying coal by reaction in a slurry mixture with a solvent consisting of an organic heavy fraction, with the application of heat, is characterized in that the slurry-based reactants are mixed with light aliphatic compounds to make use of the latent and sensible heats of the latter in lowering the reactant temperature, whereby the coal-liquefying reaction and thermal polycondensation reaction of the organic heavy fraction are controlled.
