“…Since the order of the rate of formation of butene-1 was observed to be slightly greater than two, the term in the denominator, k7 [C2H4], makes a significant contribution. In other words, reaction [6] is not completely equilibrated under the conditions of these experiments.…”

“…A system has been described using small quantities of oxygen, which gives good yields of methanol (6). For production of hydrocarbon fuels, however, the sensitizer must be a hydrocarbon and must not only provide radicals for the attack on methane but also induce a chain reaction mechanism for the formation of products.…”

The pyrolysis of mixtures of methane and ethylene has been studied over the temperature range 774-853 K at total pressures below atmospheric to explore the effectiveness of ethylene as a catalyst for conversion of methane to higher hydrocarbons. Pyrolysis of ethylene alone at these temperatures yields ethane, propylene, butene-1, and butadiene as the major volatile products. In the lower temperature region the addition of methane increased the rate of production of ethane through the chain propagation reaction, thus effecting the conversion of methane to ethane. The rates of formation of butene-1 and butadiene were not appreciably altered and that of propylene was increased only at low pressures of ethylene. At higher temperatures methane caused a substantial increase in the rate of production of propylene, the result of the increasing importance of the methyl radical in the propagation reactions. Thus ethylene can efficiently convert methane to ethane or to propylene depending on the temperature of the reaction. Addition of small quantities of butene-1 , which acted as a secondary initiator, to the mixtures increased considerably the overall rate of the conversion of methane. A mechanism is discussed which accounts for the main features of the reactions.

“…A set of over 400 reactions, see Figure 7.11.1, could be reduced to the 164 reactions of Table 7.11.1 (Refs. 34,35,36,37,38,39,40,41,42,43,44) by omitting all the reactions which had no significant contribution to the product distribution. In this way, for example the formation of methanol and reactions in which a methyl dioxygen radical is involved were skipped.…”
