چکیده    In the first part (part i) of this study, a novel fluidized bed reactor was modeled mathematically for methanol synthesis in the presence of insitu water adsorbent named sorption enhanced fluidizedbed reactor (sefmr) is modeled, mathematically. here, the nondominated sorting genetic algorithmii (nsgaii) is applied for multiobjective optimization of this configuration. inlet temperature of gas phase (tg), temperature of saturated water (tshell), total molar flow rate (ft), diameter of solid adsorbent (ds), mass adsorbent solid to mass catalyst ratio (mratio) and inlet pressure are selected as the decision variables. the production rate of methanol and selectivity is maximized as two objective functions. the shannon’s entropy, linmap and topsis methods as the three decision making approaches are applied to select the final solution of pareto front.  the optimization results approved by about 203.63 and 276.65 ton/day methanol production rate and co2 consumption, respectively, based on linmap methods compared with the conventional methanol configuration. the results recommend that consuming optimizedsefmr for improvement of methanol production could be feasible and beneficial.
