“…In addition, biogases are also frequently saturated by water vapour. The presence of CO 2 as an incombustible gas reduce its calorific value and make it uneconomical to compress and transport to longer distances [1]. Biogas purified and enriched in methane can be used for household applications, automobile fuel (liquefied) or electricity generation.…”

Abstract-A new type of mixed matrix membrane consisting of functionalized carbon nanotubes (CNTs) and polyethersulfone (PES) is prepared for biogas purification. PES mixed matrix membrane with and without modification of carbon nanotubes were prepared by a dry/wet phase inversion technique using a pneumatically flat sheet membrane casting machine system. The modified carbon nanotubes were prepared by treating the carbon nanotubes with chemical modification using Dynasylan Ameo (DA) silane agent to allow PES chains to be grafted on carbon nanotubes surface. The results from the FESEM, DSC and FTIR analysis confirmed that chemical modification on carbon nanotubes surface had taken place. Meanwhile, the nanogaps in the interface of polymer and carbon nanotubes were appeared in the PES mixed matrix membrane with unmodified of carbon nanotubes. The modified carbon nanotubes mixed matrix membrane increases the mechanical properties, the productivity and purity of biogas. For PES-modified carbon nanotubes mixed matrix membrane the maximum selectivity achieved for CO 2 /CH 4 is 36.78

“…So it is pertinent to say that the desired quality of biogas depends strongly on the application [11]. Various methods can be used to remove carbon dioxide from biogas, these are pressure swing adsorption (PSA) with activated carbon or molecular sieves, physical absorption, chemical absorption, use of organic solvents, cryogenic separation and membrane separation [9,11]. However, to remove H 2 S from biogas commonly used process are dry oxidation process and liquid phase oxidation process [12].…”

Municipal solid waste in the Kathmandu Valley and emerging cities has been a burden for the government of Nepal for over a decade. Nepal, these days, is notorious in illegal dumping of solid waste on riverbanks and crossroads at urban cities creating a serious environmental and public health problem besides destroying the city's beauty and hindering cultural and religious activities. Time and again, conflict of poorly managed landfill sites have arisen which led to halt of solid waste collection in Kathmandu valley for several days in a place where daily solid waste generation is about 500 tones of which 69 percent is of organic materials and 24 percent recyclable materials (plastics, paper, metal, glass). In order to solve the solid waste management problem in urban cities, the country failed to introduce any reliable and sustainable technology. However, among several waste management technologies available, biogas production may prove to be viable and sustainable waste to energy conversion technology. But biogas can supply energy only near to the plant, which limits its wide spread application and, therefore, bottling of biogas is a must to supply it in and around the cities and villages. In this paper we evaluate the model used in bio-based energy laboratory, Kathmandu University to upgrade and bottle biogas in a cylinder. It is found that the biogas purification, compression and storage system of Kathmandu University has net energy output 180 kWh th per cycle.

“…Among several technologies such as bioethanol, biodiesel, biohydrogen, the anaerobic digestion technology has proved to be a viable and promising technology; it is also known as a good treatment method of organic wastes. Recent life cycle assessment studies have demonstrated that biogas derived methane (biomethane) is one of the most energy effi cient and environmentally sustainable vehicle fuels [9] . At the same time, nutrients contained in the remaining digestate can be used for crop production and play a remarkable role in promoting sustainable biomass production systems.…”

“…Upgraded biogas with > 90 % methane content can be used directly as vehicle fuel or it can be injected into the gas grid. Methods for upgrading biogas for natural gas or vehicle fuel quality include: absorption of the gases in liquid solvents [9] , adsorption on solids or pressure swing adsorption (PSA) and membrane separation and chemical conversion to other compounds [10] . These separation processes are energy-intensive, require signifi cant capital investment and support services.…”

Biomethanation process is a promising eco-friendly solution for the treatment of organic biomass, which leads to effi cient bioenergy production. In this review, it is pointed out that more research and development is necessary to fi nd the best operational conditions and dedicated reactors for treating the target substrates and to make them accessible to rural areas. The present review focuses on the various approaches which can be used to solve the constraints occurring during the gas production. A brief description of possible pretreatments for converting complex lignocellulosic waste to biogas, with the desired range of operational parameters for anaerobic digestion, is highlighted. In addition, suitable reactors for different substrates are reviewed.
