  • Publication number: 20120017658
    Abstract: Biomass is preferably first prepared so as to produce the desired size, shape and moisture content. The prepared biomass is introduced along with a gasifying oxidant into a suitable gasification device to produce syngas. A mixture of air and steam may be used as the gasifying oxidant. The syngas is purified to remove particulate matter, ash, aerosols, halogens, sulphur containing compounds and volatile organometallics. The ash produced from the gasifier is collected for later use. The purified syngas is passed through a water gas shift reactor and any carbon monoxide or carbon dioxide are removed from the syngas. The gas is then passed through an ammonia synthesis reactor. The resulting ammonia is then converted into a desired ammonia product. Finally, the ammonia product and the previously removed ash are then mixed to produce a fertilizer.

    Abstract: An ammonia and fertilizer production process is based on partial oxidation of fossil fuel, which co-produces polycarbonsuboxide. The four step process is low-cost and low-carbon-dioxide emission. It comprises the steps of reacting fossil fuel with oxygen in air and steam in an electric discharge plasma to produce a gas exit stream of polycarbonsuboxide, hydrogen with associated nitrogen (110); cooling the gas stream to condense and separate the polycarbonsuboxide as a solid polymer (120); compressing the gas stream to pressures for synthesis of ammonia (140); and, converting the gas stream to ammonia by employing a catalytic converter (150). Optional steps involve gas cleanup, which include removal of contaminants from the gas stream and adding hydrogen or nitrogen to the gas stream to adjust the ratio of hydrogen to nitrogen to three to one, respectively, prior to converting the gas stream to ammonia (130).

    Abstract: A process for separating from each other heavy metals and an ash agglomerate in the form of individual granules or pellets having substrate properties. Environmentally acceptable metal chlorides and, if appropriate, fillers are mixed with the ash in a first step and the resulting mixture is subjected to agglomeration and/or compaction or conversion into particles. The agglomerate obtained in this way is heated to a temperature above the boiling point of the heavy metal chlorides. The resulting gaseous heavy metal chlorides are separated from the agglomerate. The remaining porous ash agglomerate is depleted in heavy metals and can be used as fertilizer in an original, milled or regranulated particle form.

  • Patent number: 7534281
    Abstract: The invention is directed to a process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g. sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor or tubular to form a melt; spraying the melt onto a recycling bed of fines in a granulator and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles in a to form an enhanced plant nutrient value composition (e.g. a fertilizer or soil conditioner having a greater NPK value than the original relatively low analysis organic waste material). The process further includes drawing off the fumes from the granulator, passing them through a dryer with the granulated particles, and subsequently oxidizing the fumes to eliminate volatile organic compounds and/or gaseous hydrocarbon pollutants be converting such into carbon dioxide and water vapor.

  • Patent number: 6929673
    Abstract: Concentrated phosphorus fertilizers are disclosed that comprise a buffered composition of an organic acid and salts thereof and a phosphorous-containing acid and salts thereof. The concentrated phosphorus fertilizers can be diluted with water of pH ranging from about 6.5 to about 8.5 at ratios of concentrate to water at about 1:40 to about 1:600 to result in a fertilizer having a pH in the range acceptable for foliar uptake of phosphorus.

  • Patent number: 6908495
    Abstract: The present invention is directed to a substantially odorless biological treatment process for solid and liquid organic wastes. The present invention also provides for a novel nutrient rich humus material produced from the biological treatment process. The bioconversion process of the present invention results from low oxygen concentrations and high quantities of microorganisms in a diverse microbial community.

  • Patent number: 6858058
    Abstract: In a dry or concentrated liquid fertilizer when local water is added to dilute to a working concentration, the hardness components (e.g., Ca/Mg) in the local water react with the fertilizer components and begin to form low-solubility salts. These low-solubility salts form sludges in the working mixture and begin to scale up in the feeding tubes through which the liquid fertilizer is pumped. Furthermore, the fertilizer is deprived of the nutrient values of these low-solubility salts and, as a result, the economic value of the fertilizer is reduced. By adding excess sequestering agent(s) (i.e. above the amounts needed to dissolve the nutrients in the original fertilizer formulation) precipitation of the hardening components of the local water in the mixing tank, in the feeding tubes, and in the growing media is avoided, and previous scaling can be remedied.
