  • Patent number: 7745502
    Abstract: The invention relates to a process for producing a hydrogen-rich stream from a hydrogen-depleted stream. More particularly, the invention relates to a hydrocarbon synthesis process, by way of example, a Fischer Tropsch process, from which both hydrocarbons and high purity hydrogen are obtained. The process comprises contacting the hydrogen-depleted stream with a reverse-selective membrane to provide a CO2-enriched permeate and a hydrogen-containing retentate. The high purity hydrogen is produced from the hydrogen-containing retentate. The high purity hydrogen thus obtained may be used in a process selected from the group consisting of upgrading hydrocarbons produced from the hydrocarbon synthesis process, hydrotreating a natural gas stream, recycling to the hydrocarbon synthesis reaction unit, high purity hydrogen production, catalyst rejuvenation, and combinations thereof.

    Abstract: A process for catalytic reforming of a hydrocarbon feed stream containing H2O, CO2, CH4 and CO at levels such that the H2O/CH4 is less than 0.8 and the CO2/CH4 is greater than 0.5 and the feed stream further contains quantities of sulfur compounds up to about 20 ppm. The catalyst used in this process contains from about 0.5 percent to about 25 percent by weight of a calcium compound additive, from about 2 percent to about 30 percent by weight nickel, and from about 25 percent to about 98 percent by weight of an aluminum compound carrier, wherein substantially all of the calcium is combined with the alumina. The reforming process can be utilized to produce syngas, especially low hydrogen to carbon monoxide ratio syngas for applications such as iron ore reduction.

  • Patent number: 6926880
    Abstract: A methanol reforming catalyst containing passivated copper and zinc oxide and/or alumina can be prepared by (1) precipitating or spray-drying a mixture of catalyst precursor components dissolved or suspended in a diluent in order to form a solid catalyst precursor in the form of powder or granules, (2) calcining and reducing the solid catalyst precursor obtained in stage (1), (3) passivating the reduced catalyst precursor obtained in stage (2) and (4) shaping the passivated catalyst precursor obtained in stage (3) to form the catalyst. A reduction in the volume shrinkage and an increase in the mechanical hardness during operation of the methanol reforming catalyst are achieved by the preparation process.
