Utilisation of a multitubular reactor system for parallel screening of catalysts for ring opening of decalin in continuous mode

•Catalysts activity, selectivity and stability were studied in a continuous reactor for ring opening of decalin.•Stable conversion in continuous operation mode was achieved.•Catalyst deactivation was found to originate mainly due coking.•Highest selectivity towards ring opening products was recorded over a Pt/Ir–silica–alumina catalyst.
