Two commercially available CO 2 -adsorbent materials (i.e., zeolite 13X (13X) and Lewatit® VP OC 1065 (Lewatit)) were evaluated for their applicability in a continuous temperature swing adsorption (TSA) process for biogas upgrading. The equilibrium adsorption characteristics of carbon dioxide and methane were determined by fixed bed and TGA tests. While relatively high CO 2 capacities were measured for both materials (3.6 and 2.5 mol kg), neither of them was found to adsorb significant amounts of CH 4 . Lewatit showed to be fully regenerable at 95°C, whereas for 13X, the regeneration was not complete at this temperature. However, 13X showed no degradation up to 190°C, whereas Lewatit started to degrade at 110 and 90°C when exposed to N 2 and air, respectively. Fluidization tests showed that Lewatit provides a high mechanical stability, while on the contrary, the tested 13X showed considerable attrition. An equilibrium adsorption model was fitted to the measured CO 2 adsorption data. The adsorption model was then integrated into an existing simulation tool for the proposed TSA process to roughly estimate the expectable regeneration energy demand for both materials. It was found that depending on the operating conditions, the regeneration energy demand lies between 0.32-0.54 kWh th /m 3 prodgas for 13X and 0.71-1.10 kWh th /m 3 prodgas for Lewatit. Since heat integration measures were not considered in the simulations, it was concluded that the proposed TSA process has a great potential to reduce the overall energy demand for biogas upgrading and that both tested adsorbent materials may be suitable for application in the proposed TSA process.

“…Therefore, biogas has to be purified prior to the conversion into bio-CNG. Generally, pressurized water scrubbing, pressure swing adsorption, chemical absorption, membrane permeation, temperature swing adsorption, cryogenic approach, physical absorption, and biological filtration methods are used to purify the biogas before conversion [48]. However, pressurized water scrubbing is the most commonly used method as it offers several advantages and higher percentages of CH 4 purity compared to the other purifying methods [49].…”

The need for liquid and gaseous fuel for transportation application is growing very fast. This high consumption trend causes swift exhaustion of fossil fuel reserve as well as severe environment pollution. Biogas can be converted into various renewable automobile fuels such as bio-CNG, syngas, gasoline, and liquefied biogas. However, bio-CNG, a compressed biogas with high methane content, can be a promising candidate as vehicle fuel in replacement of conventional fuel to resolve this problem. This paper presents an overview of available liquid and gaseous fuel commonly used as transportation fuel in Bangladesh. The paper also illustrates the potential of bio-CNG conversion from biogas in Bangladesh. It is estimated that, in the fiscal year 2012-2013, the country had about 7.6775 billion m 3 biogas potential equivalent to 5.088 billion m 3 of bio-CNG. Bio-CNG is competitive to the conventional automobile fuels in terms of its properties, economy, and emission.

“…Biogas is a valuable renewable energy produced from anaerobic digestion of sewage sludge, commercial composting, animal manure, residue landfill, waste biogasification and agro-zootechnical digestion in mesophilic (35 ºC) and thermophilic (55 ºC) conditions [2][3][4]. The process of biogas production takes place in four steps; hydrolysis, acidification, formation of acetic acid and formation of methane.…”

“…The process of biogas production takes place in four steps; hydrolysis, acidification, formation of acetic acid and formation of methane. Raw biogas comprise methane (40-70%), carbon dioxide (30-45%), nitrogen (0-15%) and inorganic and organic contaminants [2]. Upgraded biogas, known as biomethane, contains at least 95 % methane and less than 2.5 % carbon dioxide.…”

Abstract:In this study, an ID-GC-TOF-MS method was developed and validated for polycyclic aromatic hydrocarbons (PAHs) by spiking solutions onto thermal desorption tubes using calibration solution loading ring (CSLR) apparatus and sweeping them by the aid of air stream. Once the method was developed and validated, the effect of other compounds found in biogas and biomethane was investigated by the same methodology used in method development by using a gravimetrically prepared biogas mixture consisting of 45% methane, 40% carbon dioxide and 15% nitrogen. There are standard reference methods for measurements of PAHs in air but there was no available standard method for PAHs in biogas and biomethane yet. This study provides a basis for the future studies to develop a standard method. Data obtained through this study showed that present method is not affected by the compounds found in biogas that are not present in other matrices such as ambient air.Keywords: PAH; biogas; biomethane; thermal desorption; isotope dilution; GC-TOF-MS. © 2017 ACG Publications.

Sample SourcePolycyclic aromatic hydrocarbon (PAH) calibration solutions of consisting benzo[a]anthracene, benzo[a]pyrene and naphthalene were prepared from individual stock solutions that were prepared gravimetrically from high purity solid standards. Purities of solid standards were determined by quantitative nuclear magnetic resonance (qNMR) purity assessment protocol developed in TUBITAK UME [1].
