Aliphatic hydrocarbons with 4 – 5 carbon chain are very valuable starting materials for the steam cracking process. In terms of volume, the C4 and C5 fractions are the most important by-product streams from the pyrolysis of naphtha and other liquid raw materials. Total hydrogenation of C4 and C5 fraction is a way how to produce a high-quality raw material for pyrolysis, which in comparison with a simple recycle olefin (non-hydrogenated) fractions provides higher yields of ethylene and propylene and does not shorten the operating period of the pyrolysis furnaces by excessive coking1,2. For better understanding of the C4 fraction hydrogenating process, reaction kinetic study was performed in laboratory conditions. The hydrogenation of 2-methylpropene (isobutene) on platinum catalyst was investigated experimentally as a model reaction. The effort was focused on development of the methodology of kinetic data collection under the kinetic regime. To have a representative kinetic data, results reproducibility and process stability within several days on-stream was investigated.
