Patent number: 8815184Abstract: 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.Type: GrantFiled: June 9, 2011Date of Patent: August 26, 2014Assignee: Chevron U.S.A.

Patent number: 8562747Abstract: 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.Type: GrantFiled: April 20, 2012Date of Patent: October 22, 2013Assignee: Kawasaki Plant Systems Kabushiki KaishaInventors: Takeshi Nagahama, Noriaki Izumi
