Recent research advances and technological developments of spouted bed reactors (SBRs) have been discussed in this work. SBR has aroused increasing interest since their invention in 1955 due to its flexibility in processing different feedstocks and the high process yields that can be achieved due to its characteristic fluid dynamics. However, even though highly satisfactory results have been obtained at the laboratory scale for different applications (i.e., drying or thermochemical reactions, among others), their full implementation at an industrial level is still scarce, mainly due to the challenges encountered for their scale-up. In this work, an initial short description of SBR and configurations is followed by a review of the main experimental activities that have been conducted at different scales in the period 2013–2023. Advanced solutions such as multi-unit reactors and the use of rectangular geometries instead of the classical cylindrical ones have arisen as potential areas for further study and development to achieve a reliable implementation of the spouted bed technology at an industrial scale.

“…As already discussed, electrification is a promising approach to providing energy to catalytic systems. Electrified cracking reactions offer considerable advantages over the traditional thermal heating solutions, such as more compact equipment and pollution-free operation due the removal of fuel combustion. , Moreover, as a result of rapid and selective heating, the direct electrification offers the possibility to enhance heat transfer, therefore to minimize the coke formation on the catalyst surface, one of the limiting factors in such processes. , It should be mentioned that such an electrification concept is not only advantageous for cracking of crude oil, but also applicable to other cracking reactions such as, biomass upgrading where energy is required to sustain the reaction. − …”

The supply of the heat required for chemical processes via renewable electricity, i.e., process electrification, provides an alternative strategy for replacing conventional fossil fuel combustion. This approach enables fast, selective, and uniform heating, offers great potential for utilizing the excess renewable electric energy, and brings about an important chance for mitigating CO 2 emissions. In this work, we provide an overview of the state-of-the-art electricity-to-heat driven catalytic processes. The principle and fundamentals of Joule heating are provided and briefly compared to induction and microwave heating in view of electrifying catalytic processes. By this comparison, we assess that Joule heating can be regarded as the most promising method for process electrification, and its applications to methane reforming, cracking reactions, CO 2 valorization, and transient process operation are then reviewed. Advantages and disadvantages are critically addressed in terms of efficiency, potential for scale-up and possibility of retrofitting. The current challenges in the development of advanced electrified processes as well as the opportunities of next generation electrification techniques are discussed.

Waste plastics (e.g., polyethylene, polyvinyl chloride, polypropylene, polystyrene) and petroleum sludge (i.e., main residual from the petroleum industry) pose a severe threat to the environment and human health. These materials are basically nonbiodegradable, and it is difficult to realize the recycling of them and resources via traditional treatment methods. Catalytic pyrolysis as a new recycling treatment method has the characteristics of high efficiency, environmentally benign, no secondary pollution and high product utilization value. This paper mainly reviews the research progress of catalysts used in the catalytic pyrolysis of waste plastics and petroleum sludge. They include molecular sieves, transition metals, metal oxides, clays and activated carbons used for the recycling of plastic, and molecular sieves and M-series catalyst (M=Al, Fe, Ca, Na, K) for treating petroleum sludge. The mechanism of catalytic pyrolysis is also elucidated in this paper. In addition, the challenges faced by catalytic pyrolysis of waste polymers and the future development prospects are also presented.
