Modeling and optimizing of steam pyrolysis of dimethyl formamide by using response surface methodology coupled with Box-Behnken design

► Steam pyrolysis of DMF was studied as industrial and nuclear waste management. ► Response surface methodology (RSM) is used to optimize the process variables. ► A Box Behnken design is used to develop empirical, 2nd order, mathematical models. ► Temperature and DMF's flow rate show significant effect on the conversion of DMF. ► Optimized reaction conditions were determined for the maximum yield of N2 and CO2.
