Chemical absorption of H2S for biogas purification
(Brazilian Society of Chemical Engineering, 2004)
H2S removal capacity of supported nickel and copper oxides on mesoporous silica (H2S removal over supported metallic oxides): Capacidad de remoción de H2S de óxidos de níquel y cobre soportados sobre sílice mesoporosa (Remoción de H2S sobre óxidos metálicos soportados)Capacidad de remoción de H2S de óxidos de níquel y cobre soportados sobre sílice mesoporosa (Remoción de H2S sobre óxidos metálicos soportados): H2S removal capacity of supported nickel and copper oxides on mesoporous silica (H2S removal over supported metallic oxides)

Evaluation of sulfamethazine removal kinetics using fixed structured bed bioreactor
(2017-12-20)
The use of anaerobic biomass attached to a support has been recently presented as a good prospect in the treatment of wastewater containing recalcitrant compounds, such as sulfamethazine (SMZ). SMZ has been found in swine ...
Effect of aeration rate on the performance of intermittently aerated constructed wetlandEfeito Da Taxa De Aeração No Desempenho De Alagados Construídos Aerados Intermitentemente
(2021-03-31)
The aim of the present work was to evaluate the effect of different aeration rates on the removal of total nitrogen (TN) and chemical oxygen demand (COD) in intermittently aerated horizontal subsurface flow constructed ...
Removal of arsenic and iron from acidic water using zeolite and limestone: batch and column studies
(Springer, 2017)
Zeolite and limestone were tested for their capability of removing As and Fe from acidic water in batch and column experiments. Synthetic acidic water with 3 mg/L As and 50 or 100 mg/L Fe at pH = 2 was used in the column ...
Selecting and characterizing bacterial consortia with the potential of fixing co2 and removing h2s in a biogas atmosphere
(SPRINGER, 2014)
Biogas must be pretreated before its use; thus, both physical and chemical methods have been implemented to remove the fuel's principal pollutants (CO2 and H2S). Additional removal methods that use microorganisms' biological ...
Comparison on the removal of hydrogen sulfide in biotrickling filters inoculated with Thiobacillus thioparus and Acidithiobacillus thiooxidans
(2007-10-15)
Emissions of hydrogen sulfide (H2S) by industrial activities is frequent cause of corrosion and unpleasant odours. Treatment of gaseous emissions contaminated with H2S by biotrickling filters inoculated with single cultures ...
Copper, lead and cadmium removal by Ca Al layered double hydroxides
(Elsevier Science, 2014-01)
Layered double hydroxides are increasingly studied as heavy metal scavengers due to their acid/base buffering capacity that leads to hydroxide precipitation. Their intercalation with ligands such as edta also provides ...
Chars from wood gasification for removing H2S from biogas
(2020)
Biomass gasification is a mature thermochemical process used to produce a gaseous fuel to run burners, engines, and gas turbines. One of the byproducts of biomass gasification is char, which is a residue with low value and ...
