Abstract This study investigates the impact of ridge baffles on hydrodynamics cold hydrogenation fluidized bed reactors (FBRs) using Euler–Euler simulations. The model was validated by comparing predicted pressure drops and expansion ratios with literature results. A comparative analysis performed 3D FBRs without in terms solid holdup, gas–solid velocity distribution, fluctuation, residence time distribution (RTD). Ridge were found to effectively break up large bubbles enhance contacting...
Abstract The combined effects of particle concentration (0–20 vol%) and size on the hydrodynamics a slurry bubble column were studied by computational fluid dynamics coupled with population balance model (CFD‐PBM) in wide range superficial gas velocity (0.02–0.20 m/s). This CFD‐PBM included multiple particles, namely increased viscosity, reduced drag force, promoted coalescence, attenuated liquid turbulence, among which turbulence attenuation was crucial. To quantify attenuation, mechanistic...
Abstract A “pre‐dissolving ammonia” intensification method for continuous production of diethyl methylphosphite (DEMP) was proposed based on kinetics study methyl dichlorophosphine (MDP) substitution and DEMP acidolysis. The verified in a synthesis system consisting small jet reactor. Compared with the selectivity ~80% obtained stirred flask, reached 98% by method. Eliminating resistance gas–liquid mass transfer enhancement mixing enabled rapid removal produced HCl, thus, greatly increased....
Ultralong carbon nanotubes (CNTs) exhibit extraordinary mechanical tensile strength of over 100 GPa, and a Young's modulus 1 TPa. CNTs are considered to be one the strongest materials ever found overwhelming advantages for storing energy. In particular, great potential fabricating flywheels store kinetic energy with both high density power density, as discussed by Rufan Zhang, Fei Wei, co-workers in article number 1800680.
