Fuzzy logic control of a reverse flow reactor for catalytic oxidation of ventilation air methane

•Type-1 and type-2 fuzzy logic controllers were used to operate reverse flow reactor.•Fuzzy logic controller (FLC) is far superior to traditional logic-based controller.•FLCs of both types work well in the mitigation of ventilation air methane (VAM).•Type-1 FLC is sufficient to cope with the uncertainty for VAM mitigation.

Fuzzy logic controllers of type-1 and type-2 were implemented to deal with the high nonlinearities and uncertainties in operation of a reverse flow reactor (RFR) for catalytic oxidation of ventilation air methane (VAM). The results indicated that the fuzzy logic controller is distinctly superior to the traditional logic-based controller and works well under the conditions with high nonlinearities and uncertainties. Owing to the robustness of RFR and particular control aim of regulating bed temperature within a relatively broad range, a fuzzy logic controller of type-1 is sufficient to cope with the uncertainty brought by the extensive variation of VAM concentration.
