(orcid)0000-0003-0516-2036 Kinetic Study of Dry Reforming of Methane Over Ni–Ce/Al 2 O 3 Catalyst with Deactivation 2019 Access copy available to the general public Unrestricted A kinetic study for dry reforming of methane over Ni–Ce/Al 2 O 3 catalyst was performed, taking into account both the main reactions and the catalyst deactivation. The catalyst was prepared by a sequential wet impregnation process, with loadings of 5 wt.% Ni and 10 wt.% Ce. Experimental tests were carried out in a fixed bed reactor between 475 and 550 °C and several spatial times, using nitrogen as diluent. Several kinetic equations were compared. The best fit of experimental data was achieved using a Langmuir–Hinshelwood mechanism which takes into account the presence of two active sites. Pre-exponential factor and activation energy were calculated. the kinetics of deactivation was also determined. The relationship between catalyst activity and coke concentration was also studied. Several deactivation equations were considered in order to choose the best fit with experimental data. info:eu-repo/grantAgreement/ES/MINECO/ENE2013-44350-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.406 2019 CHEMISTRY, APPLIED 26 / 70 = 0.371 2019 Q2 T2 CHEMISTRY, PHYSICAL 95 / 159 = 0.597 2019 Q3 T2 0.727 2019 Chemistry (miscellaneous) 2019 Q1 Catalysis 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Soler, J.
