Oxidized Hydrocarbons Of Undetermined Structure Patents (Class 568/959)
  • Patent number: 9901917
    Abstract: The present invention provides methods and designs of enclosed-channel reactor system for manufacturing catalysts or supports. Both of the configuration designs force the gaseous precursors and purge gas flow through the channel surface of reactor. The precursors will transform to thin film or particle catalysts or supports under adequate reaction temperature, working pressure and gas concentration. The reactor body is either sealed or enclosed for isolation from atmosphere. Another method using super ALD cycles is also proposed to grow alloy catalysts or supports with controllable concentration. The catalysts prepared by the method and system in the present invention are noble metals, such as platinum, palladium, rhodium, ruthenium, iridium and osmium, or transition metals such as iron, silver, cobalt, nickel and tin, while supports are silicon oxide, aluminum oxide, zirconium oxide, cerium oxide or magnesium oxide, or refractory metals, which can be chromium, molybdenum, tungsten or tantalum.

    Abstract: Maintaining long residence times during hydrothermal digestion of cellulosic biomass solids may be complicated by a number of factors, including biomass compaction. Advantages in this regard may be realized by digesting cellulosic biomass solids in an inclined digestion unit. Such methods can comprise: introducing cellulosic biomass solids to a hydrothermal digestion unit comprising one or more inclined surfaces therein; introducing a fluid phase digestion medium containing a slurry catalyst to the hydrothermal digestion unit, the slurry catalyst being capable of activating molecular hydrogen; supplying an upwardly directed flow of molecular hydrogen from a source disposed along each inclined surface as the cellulosic biomass solids descend along each inclined surface; and heating the cellulosic biomass solids as they descend along each inclined surface in the presence of the slurry catalyst and the molecular hydrogen, thereby forming an alcoholic component derived from the cellulosic biomass solids.
