PRE HYDROLSYS SYSTEM OF THE ORGANIC MATTER OF THE RUBBISH AND PROCESS FOR INDUSTRIALIZATION OF THE RUBBISH

摘要

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.
