Cleaner technology for the production of linear long chain α-olefins through a “millisecond” oxidative cracking process

The oxidative cracking of n-decane was investigated at millisecond contact times over platinum alumina washcoated monoliths a fuel-air equivalent ratio (Φ) 5. High valuable linear α-olefins were so produced through an autothermal way concomitantly with oxygenated compounds, CO, CO2, H2 and H2O. A fine identification reaction products coupled the study thermal phenomena occurring both active deactivated catalysts allowed to investigate transformation mechanism discriminate heterogeneous homogeneous reactions. This process is 2-zone system involving catalytic combustion one part reactant which provides enough heat for gas phase radical transformations initiation. Long chain hydrocarbons result from decomposition intermediates such as decylperoxy radicals into aldehydes α-olefins.
