Publication number: 20100092352Abstract: 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.Type: ApplicationFiled: December 15, 2009Publication date: April 15, 2010Inventor: Robert E.

Publication number: 20090018371Abstract: 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.Type: ApplicationFiled: July 1, 2008Publication date: January 15, 2009Applicant: Range Fuels, Inc.Inventors: Robert E.

Patent number: 6863878Abstract: 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.Type: GrantFiled: July 1, 2002Date of Patent: March 8, 2005Inventor: Robert E. Klepper

Patent number: 5773234Abstract: 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.Type: GrantFiled: August 7, 1995Date of Patent: June 30, 1998Assignee: Quidel CorporationInventors: Allan D.
