Abstract:
The present invention refers to a Low Temperature Conversion apparatus composed of tri-tubes which simultaneously carries out the functions of vessel and heat exchanger. This apparatus is capable of thermally decomposing any kind of organic material to obtain coal, oil, water and non-condensable gases, and also decontaminating soils and residues contaminated with organochlorides and dioxins. The apparatus is used for thermal decomposition of any kind of organic material and comprises: an outer box (2) with a hermetic lid (19); a thermal insulation layer (5) disposed throughout the inner surface of the outer box (2) and lid, said apparatus also comprising at least a structure with three concentric tubes disposed internally, positioned substantially vertically and with a wall width suitable for heating by means of gases from an inner side and outer side of said structure. The invention also refers to a process for thermal decomposition of any kind of organic material using the apparatus of the present invention and comprises the steps of feeding the organic material into the apparatus; heating with gases on the inside and outside of an annular region located in the concentric tubes inside the apparatus; processing with extraction and condensation of oil; cooling with gases; and tilting of the apparatus.

Abstract:
The present invention relates to the average composition of urban waste, composed of plastics, paper, metal, glass, organic material of Municipal Solid Waste (OMMSW), ashes, batteries and humidity contents. OMMSW has been subjected to acidic prehydrolysis (2.5 % of H2SO4 on the dry matter), a prehydrolysate of 12 % of sugars and cellulignin with 12 % of ashes being obtained. Since the OMMSW contains only 30 % of dry matter, one has concluded that the economicity of the process defined as weight of solid matter by cubic meter of reactor improves with the mixture of 50 % of OMMSW and 50 % of biomass (wood, grass, agricultural residues, etc.). With this technique one has achieved 300kg of dry biomass/m3 (DB) of reactor. This requirement is not limiting, since the biomass may be supplied by planting trees in the urban perimeter or planting 1ha of grass for each 1000 inhabitants in the cities surroundings.
