Biomass ash, especially, wood ash has a high degree of alkalinity. As the wood ash has an alkaline environment and similarities to zeolites structure, it may be used in the electrolysis process as a solid electrocatalyst to reduce or replace chemical catalysts. For the research Design of Experiment and Statgraphics software were used. The goal of the experiment was to analyze possibilities of ash use as an electrolyte component. The statistical analysis was performed using the Statgraphics statistical data analysis tool and the empirical models with correlation equations describing pH value of analyzing samples. The results were validated using the effects of variables, the half-normal probability plot, Standardized Pareto chart, main effects plot for pH and estimated response surface for variables. The used validation methods show that there is strong correlation between pH value and used sample mixture in the experiment. Further research needed to prove the theory about possibilities of ash use as an electrolyte component.
