| Abstract | ||||
| The recent rise in energy demand to support industrialization and civilization is resulting in increased stress on conventional energy sources. Faced with the accompanying problem of climate change, research in renewable energies, especially their commercialization, has never been more important. Biogas production is a major renewable energy source. The rabbit wastes could not be completely used in biogas production as a result of certain restrictions are related with it, prevalent among these are the increase hydraulic retention time, low both gas production and calorific value this could be essentially attributed to the lower biodegradability of this wastes. So, efforts are required to take off its constraint in order to spread this technology and fully commercialized. This research focused on the design and construction of an integrated geometrical system to produce, purify, and store methane that can be implemented in commercial-size models in general and for rabbit farms especially. The results showed that the highest methane production recorded was 241.73 l/kgOTS for a three-time agitation rate of rabbit droppings. The methane concentration in the raw biogas was 57.5, 62.5 and 67.5%. The calorific values of purified biogas reached a high of 33.35 kJ/l. The methane content increased by 37.39% after undergoing the upgrading process at a constant gas pressure of 8.53 mbar and a methane proportion in the raw biogas of about 67.5%. | ||||
