The design included 17 long-term (24 h) runs, from which nonlinear regression models were fitted to the data. Five responses were measured under varying conditions: hydrogen selectivity (Y1), yield (Y2), and concentration at the reactor output (Y3). Also, the H2/CO molar ratio (Y4) and methane conversion (Y5).  aBioenergy  aCatalysts  aHydrotalcite  aResponse surface methodology  aSteam  aBiogás  aCentral composite rotatable design (CCRD)  aNiMgAlPr mixed oxides1 aMENDONÇA, I.
