Fixed bed reactors are widely used for various industrial processes, e.g. homogeneous and heterogeneous reactions. In industrial scale, when the tube is packed with catalyst, significant
operational and cost advantages can be achieved (Kayode Coker, 2001; Salmi et al., 2010). Consequently, high-throughput reactors with little or no back mixing render plug flow reactors suitable for various reactions in large-scale production. Also, modeling of tubular plug flow reactors has been reviewed in detail in literature
