[et al] - Quantification of metal-acid balance in hydroisomerization catalysts: a step further toward catalyst design. Aiche Journal. ISSN 0001-1541. Vol. 63, N.º 7 (2017), pp. 2864-28750001-15411547-5905http://hdl.handle.net/10400.21/7579A methodology was developed to interpret the results of n-.paraffins hydroisomerization over bifunctional catalysts based on two simple kinetic models used consecutively. First, a macrokinetic model was used to obtain the corresponding turnover frequency over the acid sites and the maximum of C-16 isomer yield. Second, a dual-function model was used to correlate these catalytic descriptors to the ratio of metal to acid sites of the catalyst. To illustrate the methodology, Pt/HBEA and Pt/HUSY catalysts with different Pt loadings were evaluated. The impact of metal-acid balance on the catalytic turnover frequency and the maximal C-16 isomer yield were adequately captured for the bifunctional HUSY and HBEA catalysts. Moreover, the parameters of the dual-function model revealed to be intrinsic to the catalytic properties of the zeolite under the scope. This methodology is believed to be of interest for information-driven catalyst design for the hydroisomerization of n-paraffins.engHydroisomerizationKinetic modelMetal-acid balanceZeoliteHigh-throughput experimentationjournal article10.1002/aic.15613
