The market for biogas production has been increasing every year all over the world. The use
of biogas as an energy vector is accomplished through the most diverse applications, such …

Adsorption technology has led to the development of promising techniques to purify biogas,
ie, biomethane or biohydrogen. Such techniques mainly depend on the adsorbent ability …

The presence of acid gases like hydrogen sulfide (H 2 S) in natural gas, refinery gas, and
coal gas necessitates their removal from the gas stream to prevent corrosion of pipelines …

The challenge in biohydrogen (bio-H 2) production is the presence of low hydrogen purity,
which contains a high concentration of carbon dioxide (CO 2). Bio-H 2 purification systems …

Excessive release of methylene blue (MB) in the environment and its potential infusion to
human body may cause several health issues such as blurred vision, confusion …

Anaerobic digestion produces biogas which usually contains 60-70% of methane (CH4), 30-
40% of carbon-di-oxide (CO2), and 10-2,000 ppm hydrogen sulfide (H2S). The …

Hydrogen sulphide (H2S) is a harmful material usually formed as a by-product from various
processes such as in wastewater treatment, combustion, and petroleum industries. These …

An assessment of the variability of the landfill gas components captured on a used waste
landfill site since the 1970s, was presented in the article. The amount of waste deposited in …

A two-dimensional model was developed for H 2 S chemisorption in different S-trap designs,
including (i) ZnO coated monolith channels,(ii) ZnO fixed bed, and (iii) a new design. The …

The study investigates the potential of coconut husks in purifying biogas, a common issue in
the use of biogas due to the high costs and environmental impact of expensive purification …
