“…This is problematic for quick reactions, where the reaction rate is faster than the mass transfer flux that arrives from the bulk liquid or gas to the catalytic sites in the particle [9]. An elegant way to circumvent these difficulties was suggested by Scott et al [13] and later by Hippolito group [9,12,13]: large spherical porous pellets are in reactor tube stacked in a column on each other. Such a configuration was called single-pellet-string reactor (SPSR) [13].…”

“…An elegant way to circumvent these difficulties was suggested by Scott et al [13] and later by Hippolito group [9,12,13]: large spherical porous pellets are in reactor tube stacked in a column on each other. Such a configuration was called single-pellet-string reactor (SPSR) [13]. In this geometry, the reactor diameter is close to the particle one (tube diameter/particle diameter \1.2) and the ratio between a reactor length and its diameter is very large [13].…”

“…The single pellet string reactor has been used by several authors to measure the intraparticle diffusion coefficients [9,10] and the tortuosity coefficients [11,12] in solid catalysts. The intrinsic kinetic parameters for steam reforming of n-heptane [13] and for olefin hydrogenation [14] were also measured in this type of reactor.…”
