NOVELTY - The method comprises supplying a solid organic feed material to an inlet of a pyrolysis reaction chamber (3), moving the organic material through the chamber from the inlet to a downstream end (17) of the chamber and exposing the organic material to a temperature profile within the chamber, moving the water vapor phase and the volatile products gas phase produced by heating the organic material through the chamber, and discharging the liquid water product via an outlet (39) along the length of the chamber and a dried and pyrolysed solid product from a downstream outlet in the chamber.    USE - The method is useful for pyrolysing and drying a solid organic feed material to produce valuable products such as oil, gas and char, where the: organic feed material includes biomass, peat, coal and oil shales/sands, plastic waste materials and their blends; biomass includes forestry products (including mill residues), agricultural products, biomass produced in aquatic environments such as algae, agricultural residues such as straw, olive pits and nut shells, animal wastes, municipal and industrial residues; and the coal includes peat, brown coal and black coal.    ADVANTAGE - The method is capable of rapidly, energy efficiently and economically pyrolysing and drying the solid organic feed material thus ensuring large scale production of valuable products.    DETAILED DESCRIPTION - The method comprises supplying a solid organic feed material to an inlet of a pyrolysis reaction chamber (3), moving the solid organic material through the chamber from the inlet to a downstream end of the chamber and exposing the organic material to a temperature profile within the chamber that dries and pyrolyses the organic material and releases water vapor and a volatile products gas phase from the organic material as the organic material moves through the chamber, moving the water vapor phase and the volatile products gas phase produced by heating the solid organic material through the reaction chamber in a direction counter to that of the solid organic material so that the water vapor phase and condensable components of the volatile products gas phase condense in cooler upstream sections of the chamber and form a liquid water product and a separate liquid oil product, and discharging the liquid water product via an outlet along the length of the chamber and a dried and pyrolysed solid product from a downstream outlet in the chamber. The moving of the organic material comprises moving the solid organic material and the condensed liquid oil product towards the downstream end of the chamber and drying and pyrolysing the solid organic material and volatilizing and cracking the liquid oil product into a gas phase as a consequence of the temperature profile within the chamber. The moving of the water vapor phase comprises moving the gas phases produced by heating the solid organic material and the gas phase produced by heating the liquid oil product through the reaction chamber in the direction counter to that of the solid organic material and the liquid oil product so that the water vapor phase and condensable components of the other gas phases condense in cooler upstream sections of the chamber and form the liquid water product and the liquid oil product. The method comprises operating the method until all the liquid oil product is volatilized and cracked to a non-condensable gas. The discharging step comprises discharging the liquid water product and the liquid oil product via separate outlets along the length of the chamber, discharging an off-gas phase from the upstream end of the chamber. The temperature profile in the reaction chamber comprises zones successively along the length of the chamber in which different reactions occur as the organic material moves from the upstream end to the downstream end of the chamber. The temperature profile in the reaction chamber comprises: temperatures less than 100 degrees C in a first temperature zone (water Condensation) that condenses the water vapor phase produced in the chamber and forms the liquid water product, which is removed from the reaction chamber; temperatures of 100-150 degrees C in a second temperature zone (water Vaporization) in which water evaporates from the solid organic material and moves upstream as the water vapor phase to the water condensation zone; temperatures in a range of 150-Tx degrees C in a third temperature zone (oil condensation) that decomposes the organic material and produces a part of the volatile products gas phase, where Tx is a temperature that is below condensation temperatures of condensable components of the volatile products gas phase; temperatures in a range of Tx up to 600 degrees C in a fourth temperature zone (oil vaporization) that decomposes the organic material and forms the dried and pyrolysed solid product and generates a further part of the volatile products gas phase and the dried and pyrolysed product; and temperatures in a range decreasing from 600-100 degrees C in a fifth temperature zone (char cooling), with the temperature zone recuperating heat energy in the dried and pyrolysed product. The first and second zones are water reflux region of the reaction chamber. The third and fourth zones are an oil reflux region of the reaction chamber. The method comprises injecting liquid water into the downstream end of the chamber and evaporating the water for recuperating heat energy in the dried and pyrolysed product and forming water vapor that moves upstream counter-current to the movement of solid organic material, generating the temperature profile in the reaction chamber by controlling heat transfer in the chamber, by supplying an oxygen-containing gas to the reaction chamber and partially combusting combustible gases in the reaction chamber, and supplying the oxygen-containing gas to the reaction chamber in a region of the chamber in which devolatilization of organic material is performed for producing combustible gases that are combusted by the oxygen-containing gas. An INDEPENDENT CLAIM is included for an apparatus for drying a solid organic feed material.
