PROCESS PARAMETERS AND CHARACTERISTICS FOR A CEREAL MIXTURE DURING ANAEROBIC FERMENTATION. COMPARATIVE RESULTS WITH DIFFERENT BIOMASS SUBSTRATES

摘要

The presented paper focuses on undertaken experimental aspects focused on determining the mainparameters of cereal degraded biomass, namely a mixture composed (in mass percent units) by 40 % degraded corn,40 % degraded wheat and 20 % sunflower husks, which was subjected to anaerobic fermentation inside a patent pilotinstallation for studying the available potential of input materials in order to produce biogas. Also, in order todetermine the possibilities offered by agricultural biomass, the study focuses also on comparative approach betweenthe specified batch and other sorts of vegetal biomass: two row barley and a mixture composed by degraded corngrains and corn cobs. Finally conclusions are drawn for better understanding the influence of the anaerobefermentation on this type of materials, influence which is better visible by presenting main of the materialcharacteristics (carbon, nitrogen, hydrogen content by mass and calorific value) before and after the process.
