Abstract:

Pyrolysis of 1-hexene in temperature range of 873—973 K undergoes a chain mechanism of radical reactions. Primary products consist of C1—C3 paraffins, C2—C4 olefins, butadiene, cyclopentane, cyclopentene, coke and hydrogen. The formation of various products involve different elementary reactions with varying reaction path probability(RPP). Rising temperature promotes the homolysis of the feed molecule(chain initiation) and coke formation. The average reaction chain length(KCL) decreases from 5.86 to 5.19 with increasing temperature from 873 K to 973 K.
