“…Recently, Bi and Dai [55,56] investigated the partial oxidation of methane on mixed oxide catalysts with a composition of 10 % Co/ZrO 2 , 10 % Ni/La 2 O 3 , and 10 % Co/La 2 O 3 . The authors explain the temperature difference of 50±250 K for comparable methane conversions as resulting from the formation of hot spots on oxygen defects.…”

This article reviews microwave‐assisted heterogeneous gas‐phase catalysis. To date, this special means of non‐classical energy input by microwave radiation is still a fringe area of catalysis research, and alternative reaction engineering in chemistry and chemical engineering. However, microwave‐assisted heterogeneous gas‐phase catalysis is expected to gain significant popularity in academia and industry in the near future. Experimental set‐ups that have been described in literature are critically reviewed, and concepts for the design of improved experimental set‐ups are provided in this article. Historical developments, current tendencies, and a short introduction to the theory of dielectric heating are discussed.

“…Partial oxidation of methane to syngas over Ni and Co catalysts was effected by use of microwave irradiation, and compared with conventional heating [73]. Although the same conversion levels and H 2 /CO ratio (2.0 ± 0.2) were observed, the temperature of the catalyst bed was much lower (200 K) when microwave irradiation was used than with conventional heating.…”

It is well known that microwave drying of many solid materials is a very efficient and widely used process even on an industrial scale [3]; it is also an attractive means of drying of heterogeneous catalysts. Microwave drying of catalysts and supported sorbents has several advantages:. reduction of drying time;. higher surface area and catalytic activity;. thermal dispersion of active species facilitated by microwave energy, providing more uniform metal distribution; and . higher mechanical strength of catalyst pellets.Microwave heating has been reported to produce materials with particular physical and chemical properties [4]. Stable solid structures are formed at low reaction

Microwaves in Heterogeneous Gas‐Phase Catalysis: Experimental and Numerical Approaches

This review paper focuses on the effects of microwave irradiation on heterogeneous gas phase catalytic reaction systems. Both experimental and modeling approaches are discussed. The currently available methods for temperature measurements in the microwave heating of solid particles are critically examined. The existence of microwave-created temperature gradients in beds of solid particles is discussed. The not fully established mechanism of catalyst (nano)particle heating and imperfect temperature measurement techniques implicate that different effects are often observed and contradictory conclusions are drawn. For further progress here, the development of accurate and possibly non-invasive techniques for local temperature measurements under microwave irradiation is needed.
