Biogas production from Biomass

Abstract

The purpose of this research is to evaluate the production of biogas from biomass (star grass Cynodon plectostachyus K.Schum), according to its characteristic operating parameters via uncontrolled anaerobic digestion and mass balance method by drying in laboratory heaters. This is a quantitative, exploratory and descriptive research. The sampling is probabilistic. The instruments used were: a structured guide for data collection, electric ovens, analytical set of scales, thermometers and phachimetros. The results show that the evaluated biomass is an excellent substrate for biogas production as long as the parameters characterizing anaerobic digestion are the proper ones for this process, which is achieved by making a digester with the physical characteristics and appropriate techniques. It is concluded that the parameters evaluated show that can improve the conditions of the anaerobic process using biomass so it is an issue that can further be explore and even to design pilot projects in rural areas since our tropical climate conditions favor greatly to the implementation of this technology, because the higher the temperature , further degradation of organic material occurs and decreases the size of the structures required by the system .
