  • Patent number: 8815184
    Abstract: A process for treating spent catalyst containing heavy metals, e.g., Group VIB metals and Group VIII metals is provided. In one embodiment after deoiling, the spent catalyst is treated with an ammonia leach solution under conditions sufficient to dissolve the group VIB metal and the Group VIII metal into the leaching solution, forming a leach slurry. After solid-liquid separation to recover a leach solution, chemical precipitation and solids repulping is carried out to obtain an effluent stream containing ammonium sulfate (Amsul), ammonium sulfamate, Group VB, Group VIB and Group VIII metals. Following sulfidation, the Group VIII metal is fully removed and Group VB and Group VI metals are partially removed from the Amsul stream.

  • Patent number: 8562747
    Abstract: A method and system for hydrolyzing cellulose and/or hemicellulose contained in a biomass into monosaccharides and oligosaccharides by using high-temperature and high-pressure water in a subcritical condition is provided. In hydrolyzing cellulose or hemicellulose into saccharides by using high-temperature and high-pressure water in a subcritical condition, a large amount of slurry is cooled into a condition below the subcritical condition by subjecting the slurry contained in a pressure vessel under a high-temperature and high-pressure condition to flash evaporation in a pressure vessel charged with a slurry of a cellulosic biomass and heated halfway. It is possible to prevent saccharides from degrading into organic acids and to save energy by recovery of thermal energy. The cellulosic biomass is charged into a water-permeable vessel and then the water-permeable vessel is encapsulated into the pressure vessel together with water.

    Abstract: Disclosed are a gas-liquid separator, a hydrogen generating apparatus, and a fuel cell generation system, having the same. The gas-liquid separator can include an inflow path, into which a fluid material having a liquid and a gas flows; a centrifugal path, connected to the inflow path to receive the fluid material and formed spirally such that the fluid material is separated into the liquid and the gas by difference in centrifugal forces, an outer side of the centrifugal path having stronger affinity for the liquid than an inner side of the centrifugal path; and an outflow path, connected to the centrifugal path and discharging the liquid and the gas, which have been separated in the centrifugal path. With the present invention, it is possible to efficiently separate gas such as hydrogen and liquid such as a electrolyte solution without complex devices.
