    Abstract: A gasifier feed system includes a buffer assembly that receives material, such as comminuted cellulosic material to be fed to a gasifier and includes structure that pre-processes the material for delivery to the gasifier. A source of pressurized inert gas is coupled with the buffer assembly. A rotary valve is positioned relative to the buffer assembly to receive the material from the buffer assembly. The rotary valve conveys the material to the gasifier and includes a gas lock that prevents gas from escaping the gasifier.
