Oxidation and Oxidative Dehydrogenation of Ethane and Propane

Abstract

Exploratory studies on the vapor-phase oxidation and oxidative dehydrogenation of ethane and propane have been conducted in the presence of a countercurrent "rain" of noncatalytic dispersed particulate solids which carry the heat of reaction from the reactor and maintain essentially isothermal conditions. The manner in which the independent process variables affect the conversion levels and product yields is discussed for temperatures ranging from 31 0' to 560' c., pressures from 0 to 150 p.s.i.g.,oxygen-hydrocarbon molar ratios of 0.05 to 0.6, and contact times from 1 to 28 seconds, using air or oxygen as the oxidant.

“…The controlled data set is taken from the work of Jones, et al (1969a), and is reproduced in Figure 1. The uncontrolled set, taken in conjunction with this work, is summarized in Figure 2.…”

Solids Effects on Butane and Butene Oxidation

“…This behavior is similar to but less pronounced than that observed for the low temperature oxidation of ethane at 50 p.s.i.g. (Jones et al, 1969a).…”

Unravelling the redox mechanism and kinetics of a highly active and selective Ni-based material for the oxidative dehydrogenation of ethane

“…Although ODH-C 2 has already been investigated since the 1970s, 13 at present there is still no industrial technology for this reaction concept worldwide. Several ODH-C 2 reactor concepts have been proposed in the literature: wall-cooled packed bed reactors with low d t / d p ratios, 14–22 packed bed membrane reactors 23,24 and chemical looping reactors (CL-ODH).…”
