  • Patent number: 8153027
    Abstract: This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, both oxygen and steam are added during the conversion of the feed material into syngas. The syngas can be converted to alcohols, such as ethanol, or to other products.

  • Publication number: 20100092352
    Abstract: An apparatus designed to form syn gas from carbonaceous materials such as coal includes a devolatilization reactor in combination with a reformer reactor which subsequently forms syn gas. The reformer reactor, in turn, is in communication with a particulate separator. The devolatilization reactor is fed with material using a compression feeder which drives air from the feed material, compresses it in a feed zone forming a seal between the feed hopper and the devolatilization reactor. The reformer reactor, as well as the particulate separators, are maintained in a heated furnace so that the temperature of the formed syn gas does not decrease below the reaction temperature until particulate material has been separated.

  • Publication number: 20090093555
    Abstract: This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, a catalyst is derived from the ash content of the feed material, and this catalyst is used to enhance syngas formation. The syngas can be converted to alcohols, such as ethanol, or to other products.

  • Publication number: 20090018371
    Abstract: Methods and apparatus for producing alcohols from syngas are disclosed herein. In some variations, syngas is catalytically converted to methanol in a first reaction zone, and residual syngas from the first reaction zone is then catalytically converted to ethanol in a second reaction zone. Also, in some variations, syngas is catalytically converted to methanol in high yield in a first reaction zone, and the methanol is then converted (optionally, with additional syngas) to ethanol in a second reaction zone.

  • Patent number: 6863878
    Abstract: A method of producing syn gas from biomass or other carbonaceous material utilizes a controlled devolatilization reaction in which the temperature of the feed material is maintained at less than 450° F. until most available oxygen is consumed. This minimizes pyrolysis of the feed material. The method and apparatus utilizes the formed synthesis gas to provide the energy for the necessary gasification. This provides for a high purity syn gas and avoids production of slag.

  • Patent number: 5773234
    Abstract: A lateral flow assay device for detecting the presence of Chlamydia antigen in patient's samples comprises a flow matrix including a labelling zone and a capture zone. Labelling complex comprising antibodies specific for an epitope on the lipopolysaccharide antigen of Chlamydia is present within the labelling zone. Immobilized antibody specific for the same or another epitope of the lipopolysaccharide antigen of Chlamydia is located in the capture zone. The sample containing the Chlamydia antigen will flow first through the labelling zone, where it complexes with the labelling complex, and then to the capture zone, where it is captured by the immobilized antibody. Chlamydia antigen may be extracted from a patient sample, such as a endocervical swab, by first extracting the antigen in a strong base followed by neutralization with a zwitterionic detergent and a blocking protein present in a zwitterionic buffer.
