The heat transferred from the hot reactor wall softens the raw material it contacts with under pressure. Pyrolysis moves in one direction between the biomass particles. Since the raw material is mechanically pushed forward, the remaining liquid film creates lubrication for the biomass particles. It also evaporates quickly to collect pyrolysis vapors. Pressure significantly affects the reaction rate. The advantages of the ablative pyrolysis reactor are that the particles create high pressure on the hot reactor wall due to the high relative motion and mechanical strength between the particle and the reactor wall [58].
