“…Various types of activated carbon have been investigated for H 2 S removal mainly by adsorption/oxidation to produce elemental sulfur and to a lesser extent by conversion to SO 2 Bashkova et al, 2007;Xiao et al, 2008;Pipatmanomai et al, 2009;Kwansy and Balcerzak, 2016). Pore structure and surface characteristics as well as nitrogen content of the activated carbon affect both H 2 S breakthrough capacity and selectivity toward elemental sulfur formation (Bashkova et al, 2007).…”

“…On the other hand, concluded that the surface chemistry, specifically the surface acidity, of activated carbon seems to be the key factor that plays the dominant role in the H 2 S breakthrough capacity, rather than surface area and pore volume characteristics. The relative humidity of the gas stream and alkali-impregnation were also found to be crucial to the performance of activated carbons used for H 2 S removal (Xiao et al, 2008;Pipatmanomai et al, 2009). A reaction pathway for H 2 S oxidation over activated carbon that involves the participation of all three vapor-liquid-solid phases has been proposed by and Xiao et al (2008).…”

Biogas is widely available as a product of anaerobic digestion of urban, industrial, animal and agricultural wastes. Its indigenous local-base production offers the promise of a dispersed renewable energy source that can significantly contribute to regional economic growth. Biogas composition typically consists of 35-75% methane, 25-65% carbon dioxide, 1-5% hydrogen along with minor quantities of water vapor, ammonia, hydrogen sulfide and halides. Current utilization for heating and lighting is inefficient and polluting, and, in the case of poor quality biogas (CH 4 /CO 2 < 1), exacerbated by detrimental venting to the atmosphere. Accordingly, innovative and efficient strategies for improving the management and utilization of biogas for the production of sustainable electrical power or high added-value chemicals are highly desirable. Utilization is the focus of the present review in which the scientific and technological basis underlying alternative routes to the efficient and eco-friendly exploitation of biogas are described and discussed. After concisely reviewing state-of-the-art purification and upgrading methods, in-depth consideration is given to the exploitation of biogas in the renewable energy, liquid fuels, transport and chemicals sectors along with an account of potential impediments to further progress.Keywords: biogas, upgrading, purification, utilization, SOFC, ethylene, reforming, siloxanes BIOGAS Efficient management of ever-increasing amounts of municipal, industrial and agricultural wastes in order to minimize their environmental impact is an urgent necessity. Biological treatment of wastes, which can be carried out either aerobically or anaerobically, is widely applied in this area. Due to their several advantages the anaerobic processes are to be preferred because they require considerably smaller installations, produce less sludge, operate at lower temperatures and are suited to periodic operation. Much more importantly, they generate biogas, which is an attractive potential source of renewable energy and/or added-value chemicals due to its high content of methane and CO 2 . Anaerobic digestion (AD) can proceed over a wide temperature range, from phychrophilic (ca. 10-20 • C) and mesophilic (ca. 20-45 • C) up to thermophilic (ca. 45-65 • C) and hyperthermophilic (ca. ∼70 • C) levels, by means of cooperation between anaerobes and facultative anaerobe microorganisms, which successively promote a sequence of hydrolysis-acidogenesis,

Current promising increase of agricultural investments in Croatia not only leads us to the implementation of new technologies and procedures but also leads to an increase of public awareness toward modern agricultural production. As a side effect, renewable energy sources, with special emphasis on biogas, are quickly coming under the loop. Because of this effect, a question of total biogas potential for the farming sector in Croatia becomes very important. One of the biggest obstacles in utilizing biogas on Croatian farms is its geographical displacement and small size. Through this paper economic viability and geographical distribution, as key parameters in determining realistic biogas potential on family farms, will be presented with special emphasis on the two most promising farming sectors: cows and pigs. As already mentioned, one of the biggest barriers in utilizing biogas in Croatia is the relatively small size of farms that are not capable of having economically viable biogas production. That is why community biogas plants will be important in increasing biogas utilization in Croatian farming sector. Presented methodology represents basics for regional analysis of biogas potential of a farming sector with Croatia as a case study with cost assessment of community biogas power plants considering transport distances, transport costs, and size of the power plants and family farms involved in community biogas production. The value of finding Croatia's farming biogas potential is also important since farms are high-volume energy consumers in their everyday operations and part of that energy consumption can be compensated from renewable energy sources like biogas.

“…Biogas is the combustible gas produced in a process of anaerobic digestion. According to [3], its physical and chemical properties are close to those of natural gas, although with lower methane content. This means that biogas can be used to boil water or for cooking instead of LPG, used as a fuel for process heating, used for lighting purpose, produce electricity via internal combustion engine or used in replacement of diesel or gasoline to drive machines.…”

Abstract:In this paper stability prediction for a small biogas plant in islanded mode depending on local consumers energy consumption growth is given. Biogas plant with two cogeneration facilities and local consumers is tested for on grid and islanded operation and thus represents a microgrid. Generator and regulator modelling as well as surrounding electrical grid modelling in software package Power World Simulator are described. Expected consumption growth through the period of 20 years in microgrid area is simulated. All generator important variables, i.e. voltage, frequency, real and reactive power in case of islanded mode are examined and explained. Finally, stability prediction analysis of biogas plant and surrounding consumers for 20 years period is given.
