Abstract
1. Способ получения изопрена путем дегидрирования изоамиленов на железохромкалиевом катализаторе К-24 при повышенной температуре в присутствии водяного пара, отличающийся тем, что, с целью упрощения технологии и увеличения селективности процесса, используют железохромкалиевый катализатор К-24, отработанный в условиях промышленной эксплуатации в процессе дегидрирования алкилароматических углеводородов в течение 1 - 2 лет.2. Способ по п.1, отличающийся тем, что процесс проводят при температуре 580 - 650C, объемной скорости подачи сырья 0,35 - 1,5 чи молярном разбавлении сырья паром 1 : 15 - 19.1. A method of producing isoprene by dehydrogenating isoamylenes on a K-24 iron-chromium catalyst at elevated temperature in the presence of water vapor, characterized in that, in order to simplify the technology and increase the selectivity of the process, the K-24 iron-chromium catalyst used in industrial operation is used dehydrogenation of alkyl aromatic hydrocarbons for 1–2 years. The method according to claim 1, characterized in that the process is carried out at a temperature of 580 - 650C, the volumetric feed rate of the raw material is 0.35 - 1.5 ch molar dilution of the raw material with steam 1: 15 - 19.
