Investigation of the hydrocarbon rate formation behaviour during the Fischer—Tropsch synthesis under periodic concentration forcing reveals the existence of resonance peaks for certain choices of cycle parameters. These peaks appeared under symmetrical cycling with a mean feed composition of 17–5% CO (balance H 2 ) at both low (less than 0‐001 cps) and high (greater than 0‐01 cps) frequencies for the alkanes. Although methane was more strongly stimulated under periodic operation than other hydrocarbons, the rate enhancement observed for C 2 to C 6 products signalled the potential for ‘tuning’ selectivity in this mode of operation.
