  • Publication number: 20130255153
    Abstract: Disclosed is a method of gas purification, a coal gasification plant, and a shift catalyst, each of which enables an inexpensive treatment of condensed water derived from steam used in a CO shift reaction. A CO shift reaction is performed using a shift catalyst less causing side reactions (e.g., a P—Mo—Ni-supported shift catalyst), and condensed water derived from steam used in the CO shift reaction is reused or treated. The method includes a cleaning step of removing water-soluble substances from a gasified gas containing CO and H2S; a CO shift step of allowing CO in a gas after the cleaning step to react with steam by the catalysis of the shift catalyst to convert CO into CO2 and H2; and a recovery step of removing CO2 and H2S from a gas after the CO shift step, in which post-shift condensed water formed after the CO shift step is recycled.

  • Patent number: 8481448
    Abstract: The invention is a heteropoly acid compound catalyst composition, a method of making the catalyst composition and a process for the oxidation of saturated and/or unsaturated aldehydes to unsaturated carboxylic acids using the catalyst composition. The catalyst composition is a heteropoly acid compound containing molybdenum, vanadium, phosphorus, cesium, bismuth, copper and antimony. Thermal stability is achieved with higher cesium content (up to less than 3.0) but antimony, copper and bismuth must be present to maintain good activity. The catalyst is made by dissolving compounds of the components of each of the heteropoly acid compounds in a solution, precipitating the heteropoly acid compounds, obtaining a catalyst precursor and calcining the catalyst precursor to form a heteropoly acid compound catalyst. Unsaturated aldehydes, such as methacrolein, may be oxidized in the presence of the heteropoly acid compound catalyst to produce an unsaturated carboxylic acid, such as methacrylic acid.
