Conversion of ethylene to butadiene and higher hydrocarbons in the absence of a catalyst

The conversion of ethylene to butadiene and higher hydrocarbons in the absence of a catalyst in the temperature range 973–1023 K, an ethylene partial pressure of 2–15 kPa and a flow rate of 30–150 cm³/min. The effect of the reactor free space on the overall conversion of ethylene and its selectivity has been studied. The probable steps in the formation of the principal products is discussed.Translated from Teoreticheskaya i éksperimental'naya Khimiya, Vol. 31, No. 2, pp. 95–99, March–April, 1995.This work was carried out with a grant from the Ukraine State Committee on Science and Technology.
