چکیده    The propylene production with 1-butanol co-feeding for methanol in relation to propylene process (mtp) at 440-490 °c temperature range and at 0.9-15 hr^-1 whsv range over h-zsm-5 zeolite catalyst is assessed in a isothermal fixed-bed reactor. the feedings here are of: pure 1-butanol, pure methanol and a 1-butanol and methanol mixture. the effect of 1-butanol co-feeding on selectivity of propylene is assessed through rsm an experimental design method. the results indicate that the selectivity of propylene is 69% in the feed mixture of 13, 37 and 50 wt% of 1-butanol, methanol and water, respectively. the optimum conditions to obtain high level of propylene selectivity is suggested to be at 480 °c, whsv of 0.9 hr^-1 and 1-butanol concentration of 0.135 wt.% through rsm method. the sensitivity analysis of the rsm method reveals that the whsv is the most effective parameter on the propylene selectivity with a p-value of 0.003.
