Abstract

Изобретение относится к газофазному синтезу бутадиена из этанола или этанола в смеси с прекурсорами бутадиена, такими как, например, ацетальдегид. Способ получения включает превращение этанола или смеси этанола с ацетальдегидом или другими прекурсорами бутадиена в условиях непрерывной и дробной подачи сырья разного состава в реакторе с движущимся слоем катализатора. Изобретение позволяет обеспечить высокий выход бутадиена на единицу массы катализатора и достаточный срок работы катализатора до регенерации при сохранении эффективности теплопередачи в процессе реакции.The invention relates to the gas-phase synthesis of butadiene from ethanol or ethanol mixed with butadiene precursors, such as, for example, acetaldehyde. The production method includes the conversion of ethanol or a mixture of ethanol with acetaldehyde or other butadiene precursors under conditions of continuous and fractional supply of raw materials of different compositions in a reactor with a moving catalyst bed. EFFECT: invention provides a high yield of butadiene per unit mass of the catalyst and a sufficient catalyst life before regeneration while maintaining the heat transfer efficiency during the reaction.
