“…Often, the presence of a large surface area affects the kinetics of chain reactions [37]. This does not happen in the present work: when the reactor was packed with large amounts of broken quartz, gas-phase HM-ODH was not affected (Fig.…”

We studied propylene production by the reaction of propane with oxygen in the presence of gaseous I2 which works as a gas-phase catalyst. I2 is either introduced as a gas in the mixture of propane and oxygen, or it is produced when propane and oxygen come in contact with molten LiI or a mixture of molten LiI and LiOH. The single-pass propylene yields obtained in both types of experiments are ~64%, at 500 °C and propane partial pressure of 0.1 atm. The main role of I2 is to initiate chain reactions that lead to the formation of a propyl iodide intermediate that decomposes to form propylene. Another important intermediate is HI, which reacts very rapidly with oxygen to regenerate I2 and prevent oxygen from attacking the hydrocarbons.

“…The possibility of oxidative dehydrogenation of alkanes has been recognized for many years, 39 but seems originally focused on ''kinetic coupling'' for the purpose of shifting the equilibrium to more favored products. 36 Dehydrogenation of alkanes to alkenes is an endothermic reaction described by: 23)…”

“…Oxidative Dehydrogenation. Oxidative dehydrogenation of alcohols, 171 amines, 172 or hydrocarbons 173 to carbonyl, imine, or alkenyl compounds using molecular oxygen has been extensively studied in terms of fundamental and applied aspects. The reactions for alcohols and amines typically proceed under relatively mild conditions such as an atmospheric oxygen pressure at ca.…”

Intermetallic Compounds: Promising Inorganic Materials for Well-Structured and Electronically Modified Reaction Environments for Efficient Catalysis

An overview of the catalytic properties of intermetallic compounds has been made to provide a comprehensive understanding regarding (1) what intermetallic catalysts can do, (2) their fundamental roles in enhanced catalysis, and (3) their advantages over other inorganic materials. A number of chemical transformations using intermetallic catalysts have been surveyed and classified into three major divisionshydrogenation/dehydrogenation, oxidation, and steam reforming and various subsections. The fundamental roles of intermetallic phases obtained from this survey were categorized into four types of effects: (a) electronic, (b) geometric, (c) steric, and (d) ordering effects. The unprecedented steric effects governed by the specific surface structures of intermetallic compounds highlight the unique capabilities of intermetallic materials. On the basis of this overview, we have concluded that intermetallic compounds have the following advantages for fine catalyst design: (i) control of the electronic structure, (ii) a specific and ordered atomic-level structure, and (iii) homogeneity of geometric and electronic structures. Thus, intermetallic compounds are promising inorganic catalyst materials capable of creating a well-designed reaction environment and suitable for developing efficient catalytic systems.
