<P><B>Abstract</B></P> <P>Anaerobic digestion is a multi-step biotechnological process, in which H2 is not detected as it is consumed immediately e.g. by hydrogenotrophic methanogens to produce CH<SUB>4</SUB> and CO<SUB>2</SUB>. Recently a two-stage AD concept consisting of hydrogenic process followed by methanogenic process was suggested. However, only few models of this process are known. In this study a mathematical model of a continuous process of AD with production of hydrogen and methane in a cascade of two bioreactors, including some intermediate products in the first bioreactor was developed and investigated.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Model of the anaerobic digestion for simultaneous production of hydrogen and methane in a two-stage process. </LI> <LI> Solution for determination of the optimal ratio of the working volumes of bioreactors. </LI> <LI> Static characteristics for hydrogen and methane present maxima. </LI> </UL> </P>
