ABSTRACT The main aim of this study was to remove hydrogen sulfide (H2S) from biogas by adsorption using synthesized activated carbon prepared using locally available biomass. The effect of the type of precursors, impregnation reagent and bed height was studied in continuous reactors. Three types of biomass wastes (almond shells, eucalyptus and coffee grains) were collected, grinded, sieved, pyrolyzed at 500°C and impregnated with chemical reagents such as potassium hydroxide or zinc chloride… 
Constraining bioavailable polyaromatic hydrocarbons effectively during the production and application of biochar
Abstract Biochar has substantial potential as a globally significant negative emissions technology (NET) provided that it can be deployed economically at a sufficiently large scale without
Energy Performance Analysis of B1-3.5mm Burner Model of Fasobio-15 Biodigester Biogas Cookstoves
In Burkina Faso, finding wood for cooking is still a headache for rural households due to the advancing desert. Here, we try to bring a new way for farmers who already have a biodigester and convince


Removal of hydrogen sulfide generated during anaerobic treatment of sulfate-laden wastewater using biochar: Evaluation of efficiency and mechanisms.
Findings bring a potentially novel application of sulfur-rich biochar as a source of sulfur, an essential but often deficient micro-nutrient in soils, to the table.
Adsorption of hydrogen sulfide by biochars derived from pyrolysis of different agricultural/forestry wastes
The sorption capacity of the biochar for H2S removal is related to the pyrolysis temperature and pH of the surface, which will be helpful in designing biochar as engineered sorbents for the removal of H1S.

It was demonstrated that a more acidic environment promotes the formation of sulfur oxides and sulfuric acid despite yielding small H(2)S removal capacities, and study of carbon regeneration using water washing and heat treatment showed that the adsorbents can be regenerated to about 40% of their initial capacity.
Performance evaluation of upflow anaerobic sludge blanket reactor using immobilized ZnO nanoparticle enhanced continuous biogas production
In this study, zinc oxide nanoparticles immobilized by methylenebisacrylamide were used for anaerobic consortium application and were examined for biomass retention capacity characterized in terms of
Modeling Hydrogen Sulfide Adsorption by Activated Carbon made from Anaerobic Digestion By-product
Biogas, produced from anaerobic digestion of cattle manure, is an attractive alternative energy source as it is rich in methane. However, it is necessary to remove hydrogen sulfide from the biogas
Preparation of activated carbon from peanut shell with KOH activation and its application for H2S adsorption in confined space
Abstract Hydrogen sulfide (H2S), as a major air pollutant, poses a serious threat to people`s health, especially in confined spaces. In this study, a porous carbon filter was developed by
Synthesis of Borassus flabellifer fruit husk activated carbon filter for phenol removal from wastewater
The present study investigated the adsorption of phenol from aqueous solution by adsorption onto Borassus flabellifer fruit husk activated carbon (BFAC). The activated carbon was produced by three
Biochars as Potential Adsorbers of CH 4 , CO 2 and H 2 S
Methane gas, as one of the major biogases, is a potential source of renewable energy for power production. Biochar can be readily used to purify biogas contaminants such as H2S and CO2. This study
Synthesis of activated carbon from lignocellulosic biomass and its applications in air pollution control—a review
Abstract This review compiles the work done by various researchers on synthesis of activated carbon from lignocellulosic biomass and its applications in air pollution control. The general methods for
A chemo-biological treatment of scrubbing water from power plants with recovery of value-added products
A chemo-biological approach for treating sulphate-rich effluent generated during wet scrubbing of flue gas emissions from fossil fuel fired power plants has been discussed. Microbial sulphate
