  • Publication number: 20120264197
    Abstract: A process for removing hydrogen sulfide from a raw natural gas stream such as biogas from landfills or controlled anaerobic digestion comprises passing the natural gas stream though a separation unit such as a PSA unit to form a product stream comprising a high concentration of methane and a low pressure tail gas containing hydrogen sulfide, passing the tail gas through a biofilter which includes bacteria that degrades the hydrogen sulfide to sulfur and sulfate compounds which are washed from the biofilter. The tail gas stream subsequent to treatment in the biofilter can be flared to the atmosphere without significant SOx emissions.

  • Publication number: 20100285460
    Abstract: The present disclosure, according to some embodiments, relates to phage-based biological detection systems, compositions, and methods. In some embodiments, it relates to a detection system and method using phage binding and bacterial infection to detect the presence of a target molecule (e.g., a toxin). One detection system may include a genetically engineered phage that expresses a surface molecule able to bind a target molecule and/or target microorganism; a bacterium susceptible to infection by the phage; and a detection component able to determine whether the bacterium has been infected by the phage. Infection of a bacterium by a phage may be indicative of phage binding to the target molecule and/or target microorganism.

  • Patent number: 6837917
    Abstract: A process for removal of ethylene oxide (EO) from ambient air laden with EO is passed through a zeolite-based removal media, which preferrably consists of the acid form of zeolite ZSM-5, herein referred to as “H-ZSM-5.” The process described herein may be applied to many forms, configurations and uses, such as, for example, gas masks, fume hood ventilation filters, cartridge filters, etc. Preferably, the H-ZSM-5 is configured within an apparatus in such a manner that the stream containing EO is brought into sufficient contact with the zeolite to remove the EO from the airstream.

  • Patent number: 6676913
    Abstract: The present invention relates to a catalytic process for the destruction of PFC's and HFC's using a catalyst which comprises aluminum oxide that has preferably been stabilized through the addition of a stabilizing agent (such as, titanium, zirconium, or cobalt, or mixtures of these elements). The addition of these elements to the aluminum oxide unexpectedly enhances the catalyst's stability without significantly altering its reactivity. The total amount of stabilizing agent added to the catalyst can be as low as 0.005 parts (by weight) stabilizing agent per part (by weight) aluminum oxide (Al2O3) or as great as 2 or more parts (by weight) stabilizing agent per part (by weight) aluminum oxide; so long as there is sufficient aluminum oxide available to effectively catalyze the destruction of the target PFC's and/or HFC's.

  • Publication number: 20030125203
    Abstract: A process for the decomposition of perfluoroalkanes comprises contacting a gaseous stream comprising the perfluoroalkanes with a catalyst comprising alumina. The alumina is prepared from one or more alumina sources, one of which is aluminum nitrate. The catalyst preferably comprises stabilizing agent, in particular zirconium oxide or cobalt, preferably both. The catalyst is prepared by forming a slurry of aluminum nitrate, optionally with one or more additional sources of alumina, in a suitable solvent, such as water. The resulting mixture is dried and calcined to yield the finished catalyst. The stabilizing agent or a precursor thereof may be included in the mixture or impregnated into the finished catalyst.

  • Patent number: 5851950
    Abstract: A method of treating a gaseous stream containing one or more volatile nitrogen containing organic compounds which comprises contacting the gaseous stream and an oxidizing agent with a catalyst at relatively low temperatures to cause oxidation of the volatile nitrogen-containing organic compounds. The catalyst employed promotes the oxidation reaction to selectively produce N.sub.2 O, N.sub.2, CO.sub.2 and H.sub.2 O without generating significant amounts of NO.sub.x to permit the reaction products to be vented directly into the atmosphere. The catalyst includes a selected amount of a noble or base metal deposited on a catalyst support comprising titania and zirconia. One or more of the elements molybdenum, tungsten or vanadium are added as promoters to the composition which minimizes the generation of NO.sub.x among the reaction products. Lanthanum may be added to provide better thermal stability and increase the selectivity for producing N.sub.2 among the reaction products.
