Modeling of an industrial fixed bed reactor based on lumped kinetic models for hydrogenation of pyrolysis gasoline

Study on the new hydrogenation catalyst and processes for hydrogen peroxide through anthraquinone route

“…The reactant's gas and liquid mass balance and momentum balance can be calculated using axial dispersion model based on the two-film theory, and the axial dispersion reactor model is thus achieved as the followings [13,14].…”

Modeling and operating conditions optimization of Fischer–Tropsch synthesis in a fixed-bed reactor

“…Atashi et al [13], Yates and Satterfield [14], Zennaro et al [15] and Das et al [16] have displayed the explicit rate equations based on the LHHW adsorption theory that have been developed for the cobalt-based FT catalysts in tabulated format. On the other hand some of researchers are fitted their kinetic data base on the so-called detailed models [17][18][19][20][21][22].…”

Applying reactor model parameters to estimate pygas selective hydrogenation catalyst activity during operation cycle

“…With the RK-soave method, the feed composition in Table 1 is input to calculate and obtain the surface tension (2.482 × 10 −2 N/m) and viscosity (4.204 × 10 −4 Pa s) under room temperature. The temperature effect on hydrodynamic parameters in the works of Mostoufi et al [1] and Authayanum et al [6] was not disclosed, but these physical properties were actually varying along the catalyst bed.…”

“…(1) were mostly developed according to Langmuir Hinshelwood models [6][7][8]. Others were derived with internal diffusion model [9] or assumed to be pseudo first order reaction [1,10].…”
