    摘要: The invention relates to a process and a catalyst composition for the destruction of volatile organic compounds (VOCs). The process includes the step of contacting the VOCs with an oxygen-containing gas in the presence of a catalyst which is a metal-exchanged, metal-impregnated aluminosilicate zeolite with at least one exchanged metal in the zeolite being selected from the group consisting of Ti, V, Cr, Co, Ni, Cu, Fe, Mo, Mn, Pd, and Pt, and at least one impregnated metal in the zeolite being selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Mo, Pd and Pt, and wherein the difference between the exchanged metal and the impregnated metal varies the temperature necessary to promote oxidation of the compounds and for a contact time sufficient to oxidize the compounds. The process reaction temperature can vary from about 100.degree. C. to about 650.degree. C. and the contact time can vary from about 0.01 to 20 seconds. Preferredly, the reaction temperature is from about 150.degree. C. to about 450.degree. C. and the contact time is from about 0.1 to 1.0 seconds. The CO/CO.sub.2 ratio and the Cl.sub.2 /HCl ratio in the gaseous effluent can be varied through selection of at least two impregnating metals with at least one exchanged metal in the aluminosilicate zeolite or by the use of at least one impregnating metal with at least two exchanged metals in the aluminosilicate zeolite.

    摘要: Methods, systems, and computer software for screening and assisting in screening biological specimens. Images of a biological specimen are obtained, and image data is generated from the images. Objects of interest (OOI) are identified from the image data. The OOIs are assigned to each of a plurality of fields of interest (FOIs), at least partially based on the assignment of OOIs to other FOIs. For example, OOIs that have not previously been assigned to other FOIs can be assigned to a selected FOI. In this manner, the OOIs can be grouped within the FOIs to maximize the number of OOIs included within FOIs, or alternatively, to minimize the number of FOIs required to include all of the OOIs. Once assignment of the OOIs is complete, a field of view (FOV) can be scanned relative to each FOI in order to present the OOIs to a technician, such as a cytotechnologist.

    摘要: A process and a sorbent/catalyst composition are described for the oxidation of volatile organic compounds. The process uses the steps of adsorbing a volatile organic compound in a first segment of a sorbent/catalyst bed at an adsorption temperature, followed by sequential heating of an opposed second segment of a sorbent/catalyst bed, downstream of the first segment, from an initial temperature to an oxidation temperature, desorbing the volatile organic compound from the first segment of the bed by heating, and cooling of the first and second segments of the bed respectively. The sorbent/catalyst contains an adsorption segment, e.g., metal oxides, unexchanged zeolites, carbon and polymeric resins, etc., and a catalytic segment for the subsequent catalytic oxidation of the compounds. The catalyst can be a metal-exchanged aluminosilicate zeolite having at least one exchanged metal, a metal-impregnated aluminosilicate zeolite having at least one impregnated metal, or a metal-exchanged, metal-impregnated aluminosilicate zeolite having at least one exchanged metal and at least one impregnated metal. Both the exchanged and impregnated metals are selected from the group consisting of Ti, V, Cr, Co, Ni, Cu, Fe, Mo, Mn, Pt and Pd.

These catalysts are supported or unsupported, comprising from 0 weight percent, hereinafter wt.%, to about 95 wt. % of a binder, from about 10 wt. % to about 95 wt. % of a metal-exchanged zeolite, and from about 0.2 wt. % to about 12 wt. % of an impregnating metal compound, said percentage being calculated as the metal loading on an oxide basis, where the metal in the metal-exchanged zeolite can be selected from the representative and illustrative group consisting of V, Cr, Co, Ni, Cu, Fe, Mo, and Mn and the impregnating metal compound can be selected from the representative and illustrative group consisting of compounds of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Mo, Pd, and Pt. A process for making the catalysts and a process for the oxidation of the halogenated organics are disclosed which occur at relatively low temperatures, from about 100.degree. C. to about 650.degree. C., and at pressures near atmospheric and for residence times from about 0.01 seconds to about 20 seconds.
