The instant disclosure relates to the feeding of pulverized hydrocarbonaceous solids, such as coal, coke, tar sands, oil shale, etc., into a high pressure reactor for retorting or gasification of the solids. The pulverized hydrocarbonaceous solids are mixed with a motive fluid and pressurized in a jet ejector. The pulverized solid/motive fluid mixture is then separated by a cyclone separator. The operation may be repeated in successive stages to achieve the desired pressures. The pressurized solids from the cyclone separator are introduced into the reactor, and motive fluid from the separator is recirculated to the jet ejector.
