Abstract

Изобретение относится к способу окислительного дегидрирования н-бутенов в бутадиен, включающему две или более продукционные стадии (i) и как минимум одну стадию регенерирования (ii), при котором (i) на продукционной стадии исходную газовую смесь, содержащую н-бутены, смешивают с газом, содержащим кислород, и приводят в контакт при температуре от 220 до 490°С с мультиметаллоксидным катализатором, установленным в неподвижном слое катализатора реактора с неподвижным слоем, содержащим, как минимум, молибден и один дополнительный металл, и до того, как уменьшение степени превращения при постоянной температуре достигнет более 25%, (ii) регенерируют мультиметаллоксидный катализатор на стадии регенерирования путем пропускания регенерирующей газовой смеси, содержащей кислород, при температуре от 200 до 450°С через неподвижный слой катализатора и сжигания углерода, осажденного на катализаторе, причем между двумя продукционными стадиями (i) проводят одну стадию регенерирования (ii), отличающемуся тем, что за стадию регенерирования (ii) сжигают от 2 до 50 вес.% углерода, осажденного на катализаторе.The invention relates to a method for the oxidative dehydrogenation of n-butenes to butadiene, comprising two or more production stages (i) and at least one regeneration stage (ii), in which (i) at the production stage, the initial gas mixture containing n-butenes is mixed with oxygen-containing gas and is brought into contact at a temperature of from 220 to 490 ° C with a multimetallic oxide catalyst installed in a fixed catalyst bed of a fixed bed reactor containing at least molybdenum and one additional metal, and before as a reduction in conversion at a constant temperature reaches more than 25%, (ii) a multimetallic oxide catalyst is regenerated at the regeneration stage by passing a regenerating gas mixture containing oxygen at a temperature of 200 to 450 ° C through a fixed catalyst bed and burning carbon deposited on the catalyst, moreover, between two production stages (i) carry out one stage of regeneration (ii), characterized in that for the stage of regeneration (ii) burn from 2 to 50 wt.% carbon deposited on the catalyst .
