•Low pressures have great impact on styrene conversion (yield) and selectivity.•Optimal inlet temperatures are increasing from the first to the last catalyst bed.•Radial-flow reactors are a better alternative than axial-flow when optimized.•It was obtained simultaneously styrene conversion of 76.5%...
