Abstract: Activated carbons and methods of making activated carbons are provided. The activated carbon can be produced by activating lignin or a high-lignin feedstock and then subjecting the activated carbon to a sweeping gas at a first elevated temperature.

Abstract: A method for embedding sulphur into conductive carbon is provided. Elemental sulphur is dissolved in liquid ammonia to form a sulphur-ammonia solution. Conductive carbon is soaked in the sulphur-ammonia solution to embed the conductive carbon with the dissolved sulphur. The liquid ammonia in the sulphur-ammonia solution can be removed as gaseous ammonia to yield sulphur-embedded conductive carbon. The sulphur-embedded conductive carbon can be used to manufacture sulphur cathodes. Such sulphur cathodes and batteries incorporating such sulphur cathodes are provided.

Abstract: A method of producing a fertilizer composition containing micronized sulphur wherein elemental sulphur is dissolved in anhydrous or hydrous ammonia to form an ammonia/sulphur solution and the ammonia/sulphur solution is reacted with an acidic component having at least one plant growth constituent to simultaneously form a sulphur composition comprising a sulphur compound and micronized sulphur. The thus formed fertilizer composition is dried and can be formed into various shapes such as pellets, prills, etc.

Abstract: A method of producing micronized sulphur wherein elemental sulphur is dissolved in a solvent for sulphur to produce a sulphur-solvent solution and precipitation of the dissolved sulphur is effected or controlled by manipulation of at least one of pressure, temperature or water content in the solvent to produce the micronized sulphur.

Abstract: An acid-impregnated activated carbon matrix is formed from a carbonaceous material by the addition of a mineral acid, and may be used to chemisorb ammonia from a gas stream. The ammonia reacts with the acid to form a fertilizer salt. The spent matrix may be used as a fertilizer, or the fertilizer salt may be elutriated from the matrix.
