Moving bed reactors (MBRs) have been proposed as a sign of significant progress in the reaction engineering area for performance improving and energy saving. Since their advent in 1890, the MBRs have attracted a wide acceptance in different industries, while they were first developed for the drying industries. The progress that this technology has made during its evolution led to the introduction of these reactors as a pioneer strategy in other industries including petroleum, petrochemical, pyrolysis, and biomass industries. In the traditional reaction systems, the process performance decreases during the operational conditions, while MBRs have obviated this drawback by having an all-around permanent acceptable efficiency. In this context, the present work provides an overview on the evolution of MBRs by investigating the main experimental and theoretical studies. In this way, the experimental studies have typically taken into account operational conditions and production rates of different products, while in the theoretical research, modeling, and simulation of conventional processes, the evaluation of novel configurations and the optimization techniques have been investigated. In the end, some suggestions are proposed to modify the traditional MBRs as helpful ideas for further studies.

“…Therefore, the composition of solid particles is the key for their separation. Chen et al confirmed the existence of organic compounds wrapping around solid particles by X-ray photoelectron spectroscopy and transmission electron microscopy characterization, and the outer surface of interfacial organic compounds was highly abundant in nitrogen and oxygen atoms. A solid particle separation experiment was carried out with pyridine as the flocculant through hydrogen bond interaction.…”

“…All of these problems are related to the composition of solid particles. In recent years, some researchers , have begun to realize that particles in FCC SLO are coated by organics, and the organic matters on the surface of particles may be one of the reasons for the decreased particles separation efficiency by traditional filtration, sedimentation, and electrostation methods. Therefore, the composition of solid particles is the key for their separation.…”

Agglomeration of Solid Particles in Fluidized Catalytic Cracking Slurry Oil: Particle Separation by the Oil−Water Interface and Particle Composition Analysis

Separation of solid particles in fluidized catalytic cracking slurry oil (SLO) is a tricky task because of their distinctive composition. Centrifugation and the oil–water interface method were used to separate solid particles in SLO. The results indicated that the oil–water interface method was better in particle separation. For instance, about 10 wt % fine coke powders can be separated by the oil–water interface method instead of centrifugation at the same conditions. Two different types of solid particles after ethanol/toluene extraction, i.e., catalyst fines and coke powders, were taken to investigate the composition of bulk solid particles. It was found that bulk solid particles were inborn coated by carbonaceous components rich in oxygenates and then modified by hydrogen-rich chemisorbed organics. The mechanism of particle agglomeration and separation by the oil–water interface method was proposed. Since water is cheap and accessible, this study could provide a green and efficient way for fine solid particle separation in SLO.
