Laboratory evaluation of FCC commercial catalysts. Analysis of products of industrial importance
(Elsevier Science, 2008-04)
The results of the conversion of a VGO over six equilibrium commercial FCC catalysts with different formulations in a batch CREC Riser Simulator laboratory reactor at 500 and 550 °C, catalyst to oil ratio 6.1 and reaction ...
Valorizacion de cargas residuales en refinerías
(2011-03-30)
Diversos factores motivan la mayor utilización de cortes residuales en las unidades de FCC. En el presente trabajo se desarrolló una metodología novedosa para evaluar en laboratorio la reactividad de alimentaciones comerciales ...
Comparison between MAT flow fixed bed and batch fluidized bed reactors in the evaluation of FCC catalysts. 2. Naphtha composition
(American Chemical Society, 2009-07)
A comparison was performed between the performances of a MAT type reactor(flow fixed bed) and a CREC riser simulator reactor(batch fluidized bed) in the conversion of two VGO feedstocks(aromatic and paraffinic types) over ...
Comparison between MAT flow fixed bed and batch fluidized bed reactors in the evaluation of FCC catalysts. 1. conversion and yields of the main hydrocarbon groups

(Taylor & Francis, 2015-01)
Statistical techniques for the treatment and analysis of experimental data from laboratory reactors were considered, as applied to a CREC Riser Simulator reactor for the example of fluid catalytic cracking catalyst evaluation. ...
Comment on the paper "Diffusion and adsorption selectivities of hydrocarbons over FCC catalysts" by A.M. Ávila, C.M. Bidabehere and U. Sedran [Chem. Eng. J. 132 (2007) 67-75]
(Elsevier Science Sa, 2009-01)
In a letter by Kärger [1] about our paper on the assessment of the diffusivities in fluid catalytic cracking (FCC) catalysts [2], it is mentioned that diffusivities calculated by different methods (macroscopic in one case, ...
VOx/c-Al2O3 catalyst for oxidative dehydrogenation of ethane to ethylene: desorption kinetics and catalytic activity
(Elsevier Science, 2013-01)
This study reports ethane oxidative dehydrogenation (ODH) using lattice oxygen. Ethane ODH is studied under an oxygen-free atmosphere employing a 10 wt.% VOx supported on c-Al2O3. TPR and TPO show that the prepared 10 wt.% ...
