Computational fluid dynamics (CFD) and reaction modelling study of bio-oil catalytic hydrodeoxygenation in microreactors

摘要: A computational fluid dynamics (CFD) model was derived and validated in order to investigate the hydrodeoxygenation reaction of 4-propylguaiacol, which is a lignin-derived compound present bio-oil. 2-D packed bed microreactor simulated using pre-sulphided NiMo/Al2O3 solid catalyst isothermal operation. pseudo-homogeneous first created validate experimental results from literature. Various operational parameters were investigated with data, such as temperature, pressure liquid flow rate, it found that CFD findings very good agreement The then upgraded detailed multiphase configuration, phenomena internal external mass transfer limitations investigated, well reactant concentrations on rate 4-propylguaiacol. Both models therefore confirm their ability for applications related prediction behaviour bio-oil hydrodeoxygenation.
