A cold-model experimental apparatus of the three-phase moving bed was established, which mainly consists of four parts: the inlet system, the reaction unit, the discharging and separation system, and the inner structures for even flow distribution. The pressure distribution in the moving bed reactor was investigated. The results showed that the pressure drop linearly increased with the length of the reactor in the situation without liquid, and the increasing rates were higher at larger gas velocities. Moving of solid particles further increased the pressure drop. As liquid was injected into the reactor, it made the further increase of pressure drop. The uneven distribution of liquid distorted the linearly distribution of pressure drop. The building up of cold-model experiments and the experimental results will provide guidance for the scale-up of three-phase moving bed reactors.
