This paper presents the analysis and evaluation of biogas power plant capacity in Poland based on the generic structure and energy production. These issues are also presented from the point of view of the obtained energy and biogas energy production in Poland against selected European Union countries. The paper also indicates a significant diversity in the spatial distribution of biogas plants ...

Biogas and biohydrogen, due to their renewable nature zero carbon footprint, are considered two of the gaseous biofuels that will replace conventional fossil fuels. from anaerobic digestion must be purified converted into high-quality biomethane prior use as a vehicle fuel or injection natural gas networks. Likewise, enrichment biohydrogen dark fermentation requires removal CO2, which is main p...

The purpose of the research was to study the effect of microwave power inpretreatment of fresh waterhyacinth on biogas production. The variations of microwave power levels are 240; 400; 560 and 800 W. The variations of microwave heating time are 5; 7 and 9 min. The unpretreated fresh water hyacinth are used as control. The result of research showed that the microwave pretreatment of fresh water...

BACKGROUND Enzymatic treatment of lignocellulosic material for increased biogas production has so far focused on pretreatment methods. However, often combinations of enzymes and different physicochemical treatments are necessary to achieve a desired effect. This need for additional energy and chemicals compromises the rationale of using enzymes for low energy treatment to promote biogas product...

Biogas is one of the alternative renewable energy sources that are useful in our lives. Kecamatan Jabung located Malang, has potential to produce and develop this kind resources. However, biogas contains many impurities such as H2O, CO2, H2S could have a negative impact. Therefore, it necessary purify by making an installation column. The purification process carried out utilizing solid adsorbe...

The potential use of raw and expanded perlite as low-cost adsorbents for biogas purification has been investigated. thermal expansion causes a reduction in the density silanol groups from 2515.43 to 653.75 OH/nm2; contrast, specific surface area increased two-fold due expansion. To determine equilibrium adsorption capacity kinetics batch experiments were conducted. capacities are following orde...
