However, the bio-oils obtained from such a fast pyrolysis process always have highly complex oxygenated compounds with high viscosity, serious corrosivity, and rather instability. Thus, before the raw bio-oils are used as fuel or chemical feedstock, they must be upgraded, especially deoxygenated. Cracking of bio-oils over porous solid catalysts such as zeolite-based catalysts at ambient pressure is considered one of effective ways for the bio-oil upgrading, especially in which hydrogen gas is not necessary. Herein, zeolite-based catalysts (mainly HZSM-5 based catalysts) for the upgrading of pyrolysis bio-oils are critically reviewed. The effects of porous structure, acidity and other parameters including biomass type, biomass/catalyst ratio and operation temperature on cracking activity, selectivity, stability and deactivation are summarized. While, the proposed mechanisms on the bio-oil upgrading over the zeolite-based catalysts and the possibility for the application of the developed catalysts in the industrial process are discussed. Furthermore, the main strategies including metal modification, construction of zeolites with a hierarchical structure and synthesis of special morphologies with hollow structure or core/shell structure and nanosheet structures for the improvement of deoxygenation property performance are introduced.

In this paper, the effects of column inclination and different particle-to-bed ratios (dP/dB) on the solid hydrodynamics are investigated in an inclined micro-fluidized bed. The results validated the suitability of using the Ergun equation to predict minimum fluidization velocities due to small deviations between 1.01 and 1.81 times the theoretical values, for a particle-to-bed ratio ranging from 0.025 to 0.165 at inclinations between 0° and 10°. Investigation into the effects on bed expansion behavior showed that the bed contracted with an increase in bed inclination. An unexpected observation during the bed expansion was the appearance of a secondary high voidage region and the appearance of strong circulation patterns with an increase in bed inclination. A detailed analysis of this phenomenon suggested the presence of a critical angle at 6° and 10° for the 85 µm particles, 4 × 4 mm bed cross-section and 165 µm particles, 1 × 1 mm bed cross-section, respectively.

The coarse-grained DPM based on the energy-minimization multi-scale (EMMS) model, or EMMS-DPM, was proposed to reduce the computational cost by several orders while maintaining an accurate description of the mesoscale structures, which paves the way for its engineering applications. Further empowered by the high-efficiency multi-scale DEM software DEMms and the corresponding customized heterogeneous supercomputing facilities with graphics processing units (GPUs), it may even approach realtime simulation of industrial reactors.
