Abstract

1. Способ газификации твердых углеводородов, например нефтешламов и/или гудронов, заключающийся в введении исходных реагентов в измельченном виде в расплав металла и проведении процесса газификации в присутствии паров воды и/или воздуха (кислорода) с получением в качестве продуктов реакции синтез-газа и минерального шлака, отличающийся тем, что размер частиц исходных реагентов и глубину их ввода в расплав металла выбирают из условия:,где τ- время протекания химических реакций;τ- время прогрева частиц до температуры расплава;τ- время растворения твердой компоненты частиц - углерода в расплаве;τ- время всплытия на поверхность расплава частицы шлама и продуктов ее разложения;Т - температура расплава;R - размер частиц.2. Способ по п.1, отличающийся тем, что размер частиц исходных реагентов составляет не более 1 мм, а глубина их ввода в расплав металла не менее 1 м.1. The method of gasification of solid hydrocarbons, such as oil sludge and / or tar, which consists in introducing the initial reagents in powdered form into a molten metal and conducting the gasification process in the presence of water vapor and / or air (oxygen) to produce synthesis gas as reaction products and mineral slag, characterized in that the particle size of the starting reagents and the depth of their entry into the metal melt are selected from the conditions: where τ is the time of chemical reactions; τ is the time of heating of the particles to the temperature of the melt; τ is the time of solution and the solid component of the particles — carbon in the melt; τ — time of ascent of the sludge particle and its decomposition products onto the melt surface; T — melt temperature; R — particle size. The method according to claim 1, characterized in that the particle size of the starting reagents is not more than 1 mm, and the depth of their entry into the molten metal is not less than 1 m
