The objective of the research was to determine the effect of temperature and pressure on defibrillation in grapevine pruning residues for the production of biogas in a high-efficiency anaerobic biodigester. Laboratory tests were carried out in a thermohydrolyzer designed to evaluate steam explosion thermohydrolysis and determine the effect of temperature and pressure on the defibrillation of residues from vine pruning. Subsequently, the biogas production and methane productivity were evaluated in high-efficiency reactors, according to the German standard VDI 4630, quantified based on three hydraulic residence times at 5, 10 and 15 days and with a fixed concentration of solids. at 10%. The results found show a significant effect (p <0.05) in cell rupture at a temperature of 80 ° C, however the effect of pressure was not significant (p> 0.05). Regarding the production of biogas, the...
