  • Patent number: 9809774
    Abstract: A process for separating a solid having two or more components, at least one of which is lyophobic and at least one of which is lyophilic. The process comprises, in a single step, comminuting a mixture of the solid in a first liquid to which one of the components is lyophilic and to which the other component is lyophobic and in a second liquid which is immiscible with the first liquid and which will wet the lyophobic component to form agglomerates or floes of the lyophobic component and the second liquid in a mill having positive transport capability such that the mill causes the mixture to be transported therethrough. The second liquid comprises a bio-oil, bio-diesel or combination thereof. The agglomerates are then separated from the mixture. This process may be used for beneficiating a coal containing ash.

  • Patent number: 9752088
    Abstract: A method for producing an ashless coal includes an extraction step, a separation step and an ashless coal acquirement step. In the extraction step, a slurry obtained by mixing a coal with a solvent is heated and thereby a solvent-soluble component of the coal is extracted. In the separation step, the slurry is separated into a solution of the solvent-soluble component of the coal and a solid content-concentrated liquid. In the ashless coal acquirement step, an ashless coal is obtained by evaporating and separating the solvent from the solution. The solvent is a mixture of a dissolution medium and a coal extraction accelerator added thereto. The solvent contains a bicyclic aromatic compound that is liquid at ordinary temperature. The coal extraction accelerator containing no nitrogen has two benzene rings and has at least one cyclic structure having no double bond.

  • Patent number: 9725397
    Abstract: A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream.

  • Patent number: 9683328
    Abstract: Polycarbon biofuels may be made from feedstock such as wood waste, agricultural wastes and waste paper. The feedstock may be cooked under acidic conditions to convert cellulose and similar material in the feedstock into a biofuel that is hydrophobic, readily pelletized, and has a high energy density. The biofuel may be blended with coal or other fuels to provide blended fuels that may be burned in conventional burners. One process forms a slurry of the feedstock, sparges carbon dioxide through the slurry to achieve a pH below 5 and cooks the slurry at temperatures in the range of 170 C to 300 C until conversion of the feedstock to polycarbon biofuel has occurred. The biofuel may be separated from liquids in the slurry by filtration.
