Claims (1)

Предлагается способ окисления этана до уксусной кислоты, который включает в себя подачу этана и рецуркулирующего газа в реакционную зону с псевдоожиженным слоем, содержащим псевдоожиженные частицы твердого окисляющего катализатора, подачу отдельно от названного этана газа, содержащего молекулярный кислород, при этом газ сначала смешивается в псевдоожиженном слое с главной частью подающихся сжигаемых углеводородных газов. Способ включает в себя стадии охлаждения газообразного потока, вытекающего из реакционной зоны, отделения большей части уксусной кислоты в жидком виде от вытекающих газов, покидающих газообразный поток, содержащий почти все оксиды углерода, имеющиеся в вышеуказанном вытекающем потоке, очистки небольшой части газообразного потока и рециркуляцию большей части газообразного потока как части подачи в реакционную зону, где вышеуказанная очистка служит для предотвращения накопления оксидов углерода в реакционной зоне, рециркуляция служит для поддержания высокой пропорции оксидов углерода в газах реакционной зоны, помогая тем самым уменьшать эффект подъема температуры высоко экзотермической окислительной реакции в вышеуказанной реакционной зоне.A method is proposed for the oxidation of ethane to acetic acid, which includes the supply of ethane and recurrent gas to a reaction zone with a fluidized bed containing fluidized particles of a solid oxidizing catalyst, the flow of molecular oxygen containing gas separate from the ethane mentioned, and the gas is first mixed in the fluidized bed with the main part of the supplied combustible hydrocarbon gases. The method includes the steps of cooling the gaseous stream flowing from the reaction zone, separating most of the acetic acid in liquid form from the effluent gases leaving the gaseous stream containing almost all of the carbon oxides present in the above flowing stream, purifying a small part of the gaseous stream and recirculating more portions of the gaseous stream as part of the feed to the reaction zone, where the above treatment serves to prevent accumulation of carbon oxides in the reaction zone, recycling serves to maintain a high proportion of carbon oxides in the gases of the reaction zone, thereby helping to reduce the effect of raising the temperature of the highly exothermic oxidation reaction in the above reaction zone.
