Abstract This study aimed to determine the effect of variation in biogas purification time on methane (CH 4 ) content, heating value, and combustion efficiency. The statistical analysis used was a one-way ANOVA analysis. activated bagasse biochar zeolite. variations were divided into three treatments, which are 10 minutes, 20 30 minutes. contents CH with times, respectively, 281201,45 ppm, 3135...

The purposes of this study were to prove that ammonia can be present in biogas from anaerobic digestion and to control this ammonia by reducing the reactor pH. Ammonia containing biogas was produced for a period of more than 100 days, with a maximum of 332 ppm. Especially during periods of high free ammonia concentrations in the reactor was ammonia present in biogas. The free ammonia was effect...

The purpose of this study was to evaluate feasibility study on the development of biogas in dairy farming. In short of the production process, the biogas was produced by utilizing waste from dairy farming industry (i.e. cow’s manure and cassava peel). The production of biogas was analyzed from engineering perspective with several economic evaluation parameters, including gross profit margin, in...

Natural gas is the primary source of energy, accounting for around 20% world’s energy production. It also a key element in reducing CO2 emissions due to its role stabilizing renewable sources. At same time, natural as fossil fuel that emits should be limited. A candidate can ensure stabilization RES and at time reduce demand fuels biogas. Successful use biogas requires thorough understanding po...

Biogas is a renewable fuel generated in the anaerobic digestion of organic material. The expansion biogas as bioenergy source next decades leads to find new ways for its energy exploitation such Chemical Looping technologies. In this work, low-cost Fe-based residue was used oxygen carrier two processes with biogas, namely Combustion (CLC) and Reforming (CLR). CLC process focused on production C...

Most organic matter can be used for bioenergy generation via anaerobic fermentation. Today, crop plants like maize play the dominant role as substrates for renewable biogas production. In this work we investigated the suitability of six dominant microalgae species (freshwater and saltwater algae and cyanobacteria) as alternative substrates for biogas production. We could demonstrate that the bi...

Several factors can influence the process of biogas production. The type of reactor is one of the key factors that influence biogas production. Therefore, the aim of this study was to construct a portable horizontal polyethylene-based biogas reactor. In addition, the performance of the developed biogas reactor was tested through digestion of cow manure. The experiments were carried out in Mashh...
