(orcid)0000-0003-0516-2036 Conventional and improved fluidized bed reactors for dry reforming of methane: Mathematical models 2020 Access copy available to the general public Unrestricted Dry reforming of methane is a potentially useful reaction, but has some drawbacks: catalyst deactivation by coke and yield limited by thermodynamic equilibrium. New improved fluidized bed reactors may compensate these disadvantages. Mathematical models for the dry reforming of methane in three types of fluidized bed reactors have been developed. These reactors include: a) conventional fluidized bed reactor, b) two zone fluidized bed reactor, which provides simultaneous reaction and catalyst regeneration in a single fluidized bed, and c) two-zone fluidized bed reactor with hydrogen selective membranes, which in addition to the previous one provides increased yield to hydrogen, because the selective removal of hydrogen through the membrane. The situations where these reactors counteract the two main drawbacks of dry reforming of methane are shown. Comparison with previous experimental results shows that the models predict well the effect of operating conditions. info:eu-repo/grantAgreement/ES/MINECO/CTQ2016-76533-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 13.273 2020 ENGINEERING, ENVIRONMENTAL 2 / 53 = 0.038 2020 Q1 T1 ENGINEERING, CHEMICAL 4 / 143 = 0.028 2020 Q1 T1 2.528 2020 Chemical Engineering (miscellaneous) 2020 Q1 Industrial and Manufacturing Engineering 2020 Q1 Environmental Chemistry 2020 Q1 Chemistry (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Soler, J.
