This thesis deals with the technology of the high pressure hydrolysis with nitric acid (HNO3) in biogass production from the hay. The theoretical part is focused on the basic information about the acid hydrolisis. Much attention is ingaged in the lignocellulosic materials and methods of their treatment.The hay was crushed, pelleted and subsequently subjected the acid hydrolysis in the high-pressure hydrolyzer (UV CZ 21314) at pressures (0,475 MPa, 0,934 MPa, 1,611 MPa). As the hydrolysis reagent was used highly concentrated (65%) nitric acid (HNO3). The pressure was achieved in the hydrolyzer by the steam in temparature of 190°C, the residence time of the phytomass in the machine was 500s. Based on the mapping process with wide CO2 production were selected the interesting areas, which were subsequently carried out detailed mapping process using batch simulations at CH4 production. After the mathematical interpolation of the maxima the values were used in the economic analysis, that fully respects the technological possibilities and legislative constraints.
