  • Patent number: 10604455
    Abstract: The present invention relates to a process for preparing an aromatic hydrocarbon, and processes for producing p-xylene and terephthalic acid. The process for producing said aromatic hydrocarbon comprises a step of contacting an olefin with a diene in the presence of a catalyst to produce an aromatic hydrocarbon, which is characterized in that, at least a part of said olefin is substituted with dienophile. The reaction pressure can be reduced and the xylene selectivity can be increased with the improvement of the present invention.

  • Publication number: 20140308597
    Abstract: The invention provides a process for producing H2 by steam reforming of methanol, which process comprises contacting a gas phase comprising (a) CH3OH and (b) H20 with a solid catalyst, which solid catalyst comprises a mixed metal oxide, which mixed metal oxide comprises copper, zinc and gallium, wherein the atomic percentage of copper relative to the total number of metal atoms in the oxide is from 20 at. % to 55 at. %. The solid catalyst itself is also an aspect of the present invention, as is a process for producing the catalyst, which process comprises: (1) a co-precipitation step, comprising contacting: (a) a solution of copper nitrate, zinc nitrate and gallium nitrate, wherein the atomic percentage of copper relative to the total number of metal atoms in said solution is from 20 at. % to 55 at.

  • Publication number: 20080113401
    Abstract: Assays for detecting potentially toxicdanalytes utilize a preparation of eukaryotic or prokaryotic cells which have signal-generating metabolic activity. The sensitivity of such assays is significantly improved by the employment of a particulate solid-phase adsorbent e.g. silica gel, which can be preliminarily mixed either with the suspected toxic analyte or with the cellular reagent. It is found that the presence of either the adsorbent-analyte combination or the adsorbent-cellular reagent combination results in an amplification of the decrease of the intensity of the generated signal, thereby improving the detection capability of the assay, particularly with respect to low concentrations of toxicants.

  • Patent number: 7214505
    Abstract: Cell-based reagents and methods of using the reagents for detecting analytes are provided. The adsorbing of cells with signal-generating metabolic activity to solid supports has been found to improve the sensitivity of known cell based assays. Signal-generating cells adsorbed to a solid support are introduced to a test agent, and the measured decrease in metabolic signal provides a measure of the toxicity of the test agent.
