Abstract
An apparatus and method utilize liquid pressurized lock hoppers to feed solids to a high pressure vessel. Solids are introduced to a first lock hopper, and gases are passed to the first lock hopper from a second lock hopper which has previously discharged solids. Liquid is supplied to the first lock hopper so as to attain a pressure equivalent to the pressure of the high pressure vessel. Solids are discharged from the first lock hopper to a high pressure vessel after pressurization.
