Operation of FCC with mixtures of regenerated and deactivated catalyst
(Elsevier Science, 2001-07)
The operation of FCC with mixtures of coked and regenerated catalyst was studied with a riser simulator reactor on two equilibrium catalysts at 550◦C. The coked catalysts maintain an activity level that enables them to be ...
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 ...
Spent FCC catalyst for preparing alkali-activated binders: An opportunity for a high-degree valorizatio
(2014-01-01)
Spent FCC catalyst is a waste from the petrochemical industry which has excellent pozzolanic properties, containing more than 90% silica and alumina. Its similarity to metakaolin creates interesting prospects for its use ...
Exhausted fluid catalytic cracking catalysts as raw materials for zeolite synthesis
(Elsevier Science, 2006-07)
The utilization of exhausted fluid catalytic cracking (FCC) catalysts as raw materials for the zeolite synthesis was analyzed. Samples of the catalysts directly released from FCC units and the corresponding impact grinding ...
Conversion of Cow Manure Pyrolytic Tar Under FCC Conditions Over Modified Equilibrium Catalysts
(Springer, 2019-01)
Changes were produced by means of alkaline lixiviation in the porosity of an equilibrium commercial FCC catalyst formulated to maximize the yield of middle distillates, in order to improve its performance in the conversion ...
Trivalent chromium ion removal from aqueous solutions using low-cost zeolitic materials obtained from exhausted FCC catalysts
(Sage Publications, 2011-07)
The hydrothermal treatment of exhausted FCC catalysts with zeolite was optimized by varying the chemical composition of the synthesis mixture. The zeolitic products obtained were used to evaluate their ability for the ...
Reliable laboratory reactor data analysis: Evaluation of commercial FCC catalysts in a batch fluidized bed reactor
(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. ...
