| Resumo: | Methane is the main constituent of biogas, being responsible for its calorific value. This work objective was to present the analysis of methane concentration in the biogas originated from anaerobic treatment system of wastewater of coffee wet processing (CWP) at laboratory scale, using coffee coconut. The methane concentration were performed by gas-solid chromatography (GSC) analyses. The system was composed of a column Restek RT-Q-PLOT, with the stage sets, the divinyl-benzene, nitrogen as mobile phase and a flame ionization detector (FID). The results of the concentration of methane in the biogas ranged from 48.60 to 68.14%. The upper and lower calorific values were 25,654 and 23,777 kJ.m-3, respectively. For interchangeability, obtained a Wobbe number of 7,851 kcal.m-3, resulting in theirinterchangeability with piped gas (city gas). |
