Abstract

Способ получения н-бутиленов путем дегидрирования н-бутана на алюмохромовом катализаторе в присутствии добавки, содержащей бутадиен, при повышенной температуре, отличающийся тем, что, с целью упрощения технологии процесса и увеличения выхода н-бутиленов, в качестве добавки, содержащей бутадиен, используют фракцию ацетиленовых углеводородов - отход выделения бутадиена экстрактивной ректификацией диметилформамидом из контактного газа дегидрирования бутиленов, взятую в количестве 0,1 - 1,0 мас.% на сырье.The method of obtaining n-butylenes by dehydrogenating n-butane on an aluminum chromium catalyst in the presence of an additive containing butadiene at elevated temperature, characterized in that, in order to simplify the process and increase the yield of n-butylenes, a fraction is used as an additive containing butadiene acetylene hydrocarbons - waste from the release of butadiene by extractive distillation of dimethylformamide from the contact gas of dehydrogenation of butylenes, taken in an amount of 0.1 - 1.0 wt.% for raw materials.
