A solid feed system may comprise a supersonic nozzle, an isolated injection section having a port for injection of solid feedstock positioned downstream from the supersonic nozzle, and a supersonic diffuser positioned downstream from the isolated injection section. Additionally, a gasification system may comprise such a solid feed system and a reaction chamber downstream thereof. Furthermore, a method of reacting a solid feedstock under pressure may include directing a fluid flow through a supersonic nozzle to provide a supersonic flow stream, and directing the supersonic flow stream through an isolated injection section at a static pressure at least fifty percent (50%) lower than an operating pressure within a reaction chamber (e.g., at a static pressure near ambient pressure).
