Although the material of construction of the reactor used for the partial oxidation of light paraffins has a major effect on both the composition of the product obtained and on the kinetics of oxidation, the present investigation is the first one to investigate several reactors systematically over a wide range of operating conditions. Glass, aluminum, steel, and copper reactors were employed in the present investigation for partial oxidation of both methane and propane. Postulates proposed earlier to explain the role of the surface do not explain all results. The reactor surfaces were found in many cases to catalyze surface reactions.Numerous previous investigators have presented experimental information that indicates partial oxidation results often vary significantly in reactors with different materials of construction or with different pretreatments of the inner surfaces. Several postulates have been proposed Reid, 1954, 1961;Semenov, 1958;Knox, 1968; Baldwin et al., 1970;Euker and Leinroth, 1970) that explain relatively well certain results obtained over rather limited experimental conditions, but no postulate proposed to date explains results obtained over wide ranges of conditions. A proposed mechanism should explain both the kinetics'and composition of products obtained.In a steel reactor operated at atmospheric pressure, a relatively constant rate of oxidation of propane occurred over the entire range of oxygen conversion from essentially 0 to 100%

“…The horizontal apparatus (Meguerian, 1963) consisted of fuel-measuring and delivery systems, a preheater-reactor assembly, a temperature-programmed furnace with instrumentation for controlling and measuring temperature, and the conventional systems for handling and metering gases. The preheater permitted separate heating of the reactants, fuel (diluted with nitrogen), and oxygen, to a constant temperature of 200°C.…”

“…Some of the termina-1 Present address, Wayne State University, Detroit, Mich. tion steps for the chains are known to occur on the surface. Several investigators (7,7,12) have rather recently postulated that at least some of the initiation reactions also occur on the wall. Initiation might occur, for example, by the following surface reactions postulated by Semenov (20):…”

“…For many years, acetaldehyde has been known to promote the gasphase oxidations (11,13), but the present results clearly indicate that it has a surface role too. Mequerian (12) found in a flow reactor that aldehydes sometimes deactivated the reactor.…”
