Investigation of the process conditions for hydrogen production by steam reforming of glycerol over Ni/Al2O3 catalyst using response surface methodology (RSM)

In this work; a response surface methodology (RSM) was implemented to investigate the process variables in a hydrogen production system. The effects of five independent variables; namely the temperature (X1); the flow rate (X2); the catalyst weight (X3); the catalyst loading (X4) and the glycerol-wa...
