The Effect of Hexene-1 in Feedstock on the Yield of Target Products during Thermal Pyrolysis ofn-Hexane

摘要

The effect of the alpha-olefin addition in the pyrolysis feedstock on the yield of ethylene, propylene, and divinyl (butadiene-1,3) was studied using then-hexane-hexene-1 model system under conditions of a laboratory flow-type thermal pyrolysis setup. It was found that the total yield of unsaturated hydrocarbons C-2=-C(4=)depends on the ratio ofn-hexane : hexene-1 in the initial mixture and is characterized by a maximum value at a 0.36 molar fraction of hexene-1 in feedstock. The main directions of reactions in the presence of an alpha-olefin are discussed.
