METHOD OF ORGANIC WASTE PROCESSING Russian patent published in 2003 - IPC

FIELD: organic waste utilization by gasification. SUBSTANCE: invention relates to the sphere of the organic waste utilization by gasification with following catalytic conversion of the produced synthesis gas in the liquid engine fuels and/or valuable chemical products. Invention also presents the method of processing of the organic waste materials, that provides for a stage of their gasification by the waste products processing with the help of a gasifying agent at the presence of a combustible gas with production of synthesis gas and the solid inorganic products, catalytic processing of synthesis gas, in which the gasifying agent contains oxygen and water steam and/or carbon dioxide, and in the capacity of a combustible gas they use natural gas under volume ratio of oxygen / natural gas equal to 0.01-0.5. The synthesis gas produced as a result of the gasification is compressed, exposed to the fine cleaning from mechanical impurities and compounds of sulfur, nitrogen, heavy metals. Then this compressed and cleaned synthesis gas or the synthesis gas together with the liquid organic waste materials is fed into a reactor of hydrocarbon synthesis and exposed using the bifunctional catalyst containing oxides of zinc and chromium or zinc, chromium and copper or iron, or cobalt and ruthenium in a combination with an acid component - zeolite of type of ZSM-5, Beta, mordenite or silicoalumophosphate, to transformation into liquid motor fuels or liquid motor oils and components of the base of oils. EFFECT: the invention allows to improve the quality of the produced synthesis gas by increasing the share of hydrogen and decreasing the share of the carbon dioxide, necessary for increase of the output of the marketable product at the following catalytic stage of hydrocarbons synthesis. 6 cl, 9 ex, 1 dwg
