Sumario:Co-gasification is an efficient process for obtaining valuable by-products from blending different raw materials. However, selecting the optimum blend is complicated to establish as it depends on the criterion selected. In this study, the Analytical Hierarchy Process was used for obtaining the optimum blend in the co-gasification of olive pomace, almond shells and petcoke. Thus, four criteria (H2/CO ratio, gasification reactivity, CO2 burden and raw material price) and fifteen alternatives were proposed. Moreover, a sensitivity analysis was made to determine potential changes in the alternatives ranking. At this point, 29 scenarios were considered for evaluating all possible interactions between the criteria. The optimal sample depended on the scenario studied, which meant criteria weightages were significant. Moreover, a normalized priority ranking was calculated by taking all scenarios into consideration. Finally, the olive pomace and the blend of 75wt. % of olive pomace and 25wt. % of petcoke presented the best results.
