Appl. No.:

11/299030

Inventors:

Chan Seung Park - Yorba Linda CA, US
Colin E. Hackett - Riverside CA, US
Joseph M. Norbeck - Riverside CA, US

International Classification:

G01N 33/00
G01N 33/22
G01N 31/12
G01N 25/18

US Classification:

436134, 436144, 436137, 422 78, 422 94, 422 95, 73 2321, 73 2331, 73 2503

Abstract:

An assembly and method for gas analysis. The assembly comprises a catalyst compartment for catalytically reacting a component of a gas sample, producing one or more gas species as products. A product compartment receives the gas species, and a sensing element within the compartment senses the amount of one or more of the gas species. This amount is compared to the amount of the same gas species present in a reference compartment containing a non-catalyzed gas sample, providing the amount of the gas species produced by catalysis. Using this value, the content of the gas component in the gas sample is calculated based upon the stoichiometry of the catalyzed reaction. In preferred embodiments, the gas for analysis is a process gas for fuel production, and the catalyst is a high temperature shift catalyst that catalyzes the reaction of carbon monoxide and water into hydrogen and carbon dioxide.

International Classification:

F02B 43/00

US Classification:

123 1A, 123494

Abstract:

An apparatus and method for utilizing any arbitrary mixture ratio of multiple fuel gases having differing combustion characteristics, such as natural gas and hydrogen gas, within an internal combustion engine. The gaseous fuel composition ratio is first sensed, such as by thermal conductivity, infrared signature, sound propagation speed, or equivalent mixture differentiation mechanisms and combinations thereof which are utilized as input(s) to a “multiple map” engine control module which modulates selected operating parameters of the engine, such as fuel injection and ignition timing, in response to the proportions of fuel gases available so that the engine operates correctly and at high efficiency irrespective of the gas mixture ratio being utilized. As a result, an engine configured according to the teachings of the present invention may be fueled from at least two different fuel sources without admixing constraints.

International Classification:

C07C 27/00

US Classification:

518700, 518703, 518704, 518705, 518706

Abstract:

A method and apparatus for converting carbonaceous material to a stream of carbon rich gas, comprising heating a slurry feed containing the carbonaceous material in a hydrogasification process using hydrogen and steam, at a temperature and pressure sufficient to generate a methane and carbon monoxide rich stream in which the conversion time in the process is between 5 and 45 seconds. In particular embodiments, the slurry feed containing the carbonaceous material is fed, along with hydrogen, to a kiln type reactor before being fed to the fluidized bed reactor. Apparatus is provided comprising a kiln type reactor, a slurry pump connected to an input of the kiln type reactor, means for connecting a source of hydrogen to an input of the kiln type reactor; a fluidized bed reactor connected to receive output of the kiln type reactor for processing at a fluidizing zone, and a source of steam and a source of hydrogen connected to the fluidized bed reactor below the fluidizing zone. Optionally, a grinder can be provided in the kiln type reactor.
