Simulation of reverse flow operation for manipulation of catalyst surface coverage in the selective oxidation of ammonia

Decomposition kinetics of ammonia in gaseous stream by a nanoscale copper-cerium bimetallic catalyst

“…Thus, the proposed kinetic models proved to predict reaction mechanism and rates satisfactorily. The result is similar to that described in relevant literature [31][32][33][34][35].…”

Numerical simulation of methane fuelled cogenerative SOFCs for the production of synthesis gas and electrical energy

“…This can be combined with the dynamic forced periodic flow reversal of the SOFC operation that was shown to be very successful for the autothermal processing of reaction mixtures with very low heating values (Matros, 1989). Several applications of this technique refer to SO 3 production from metallurgic off gas containing SO 2 (Matros, 1989), the catalytic purification of waste gases (Eigenberger and Nieken, 1988), methanol synthesis (Neophytides and Froment, 1992), methane combustion (Kushwaha et al, 2004) and selective oxidation of ammonia (Budhi et al, 2004). Ferreira et al proposed reversed flow operation as a way to improve the temperature distribution along the bed for o-xylene oxidation to phthalic anhydride (Ferreira et al, 1999).…”

A Mathematical Study on the System of Partial Differential Equations Describing Reverse-Flow Reactor

“…They are also observed in numerical simulations with the aid of mathematical models, see [7,10,11,14,15,16,17] and references therein. According to numerical simulations by Budhi et al, complicated and sensitive asymptotic behavior of solutions can be observed, see [2]. For this reason, it is important to analyze RFR not only by experiments but also by using mathematical models.…”
