Experimental Investigation on Expanded Granular Sludge Bed Reactor to Maximize the Methane Gas Production in the Biogas

摘要

The increase in the global temperature, the greenhouse gas emissions, air pollution and the instability in the fossil fuel prices played an important role in making the world more aware of the renewable energy developments, By most definitions alternative energy(have low carbon emissions, a distinction which separates it from renewable energy which may or may not have significant environmental impact. The Anaerobic Digestion Process, is one of the most contributed renewable energy sources as it generates biogas that could be used for heating and powering purposes, it could be used also in all equipment designed for the natural gas with minimal adjustment to account for the lower BTU content of the methane gas, upgrading the biogas sometimes is preferred in order to increase the composition of the methane gas in it. In general, the biogas consists of methane gas about 50-70% and carbon dioxide 30-50%.
