A five-level Central Composite Rotational Design (CCRD 23, with 3 central (0) and six axial points) was performed to optimize hydrogen production via the continuous-flow-steam biogas reforming (SBR) reaction over a nickel-based catalyst, composed of Mg–Al oxides derived from hydrotalcite and containing 10 % of Ni and 1 % of praseodymium. 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). |
