  • Patent number: 8979952
    Abstract: The invention relates to the improvement of the fuel-properties of biomass in an integrated manner to facilitate storage, shipping and applicability thereof. In the process, biomass (6) is thermally treated within a combustion process to cause partial torrefaction of the organic matter present in biomass, thus yielding components inert to biological decomposition processes. Constituents (10) separated in gaseous form are utilized as fuel, while the thermally treated biomass (8) remaining in the solid form is utilized in a separate process.

  • Patent number: 8100990
    Abstract: Methods, process, apparatus, equipment, and systems are disclosed for converting biomass into bio-oil fractions for chemicals, materials, feedstocks and fuels using a low-cost, integrated fast pyrolysis system. The system improves upon prior art by creating stable, bio-oil fractions which have unique properties that make them individually superior to conventional bio-oil. The invention enables water and low-molecular weight compounds to be separated into a final value-added fraction suitable for upgrading or extracting into value-added chemicals, fuels and water. Initial bio-oil fractions from the process are chemically distinct, have low-water content and acidity which reduces processing costs normally associated with conventional bio-oil post-production upgrading since fewer separation steps, milder processing conditions and lower auxiliary inputs are required. Biochar is stabilized so that it can be handled safely.

    Abstract: The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3% by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.

  • Patent number: 5601692
    Abstract: A continuous process for treating a noncaking coal to form stable char. The process includes the sequential steps of drying the coal to remove moisture therefrom and form a dry coal; pyrolyzing the dry coal by progressively heating substantially all of the coal to a temperature sufficient to vaporize and remove low end volatile materials from the coal to form char and sufficient to mobilize at least a portion of high end volatile materials within the char and at least partially collapse micropores within the char. The char is then cooled to a temperature sufficient to demobilize the volatile materials within the at least partially collapsed micropores of the char to pyrolytically passivate the char. The char is then conveyed to a reaction vessel wherein a process gas having about 3%-21% by volume oxygen flows through the reaction vessel to oxidatively passivate the coal by chemisorption of oxygen.
