Characterizing activated carbon synthesized from corn straw aiming water treatment
Silva T., Souza I., Silva C., (Corresponding) Abud A.
Topic:
Environmental biotechnology and bioenergy
The emerging agenda for sustainable development and global warming control searches urgent researches to reduce environmental impacts. In this sense, activated carbons from agroindustrial wastes are widely used as adsorbents in food and pharmaceuticals industries, mainly for the separation and...Read more
Production of activated carbon from oil palm shells via physical activation with H2O and its characterization for use in aqueous phase
(Corresponding) Rincon S., Alvarez D.
Topic:
Energy technologies and sustainability
Oil palm shells (OPS) are a solid residue of the extraction of palm oil having excellent characteristics for production of activated carbon. OPS worldwide production amounts to 17.214 ton (2018) from which Colombia participates with 364 ton. Oil palm shells were first carbonized in a horizontal...Read more

Heat of adsorption in the fly ash zeolite – CO2 system at dynamic conditions
Zgureva D., (Corresponding) Boycheva S., Marinov I., Miteva S., Asenov A.
Topic:
Climate change mitigation and adaptation
The global warming represents one of the main world problems in the recent decades as it is considered that electricity production by coal burning is responsible for 40 % of the total CO2 emissions. The post-combustion capture of CO2 based on physical adsorption has the highest potential for...Read more

Comparative studies of the equilibrium adsorption of CO2 onto coal ash zeolites Na-X and Na-Ca-X
(Corresponding) Boycheva S., Marinov I., Miteva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
Coal-fired Thermal Power Plants (TPPs) are the main source of greenhouse gas emissions in the atmosphere, but they also generate huge amounts of solid by-products, including fly ash (FA). A modern strategy for sustainable energy production is to improve the ecology of the TPPs by developing...Read more

Adsorptive Removal of Marbofloxacin from Milk using Activated Carbons.
GE X., WU Z., KUNZ W., Barge A., (Corresponding) Giancarlo C.
Topic:
Water and wastewater treatment and reuse
The present study aims to remove the residual marbofloxacin (MBX) from milk with activated carbons (ACs) in batch and flow systems to meet the maximum residue limits (MRLs, 0.075 µg mL-1). Different types (granular and powder) and amounts of ACs were studied. In batch mode, 50 mg of commercial...Read more
Activated carbon-polyethyleneimine-alginate composite fiber for scavenging pharmaceuticals with different charges from aqueous solutions
Dangi Y., Choi J., Lim C., Song M., Han M., Lin X., (Corresponding) Yun Y.
Topic:
Water treatment
Activated carbon (AC) is a potential adsorbent for water purification, though it is difficult to separate after use. To solve this problem, for the first time, the ternary composite fiber (ACPEIA) of AC, polyethyleneimine (PEI), and alginate (A) was fabricated as a multifunctional adsorbent for...Read more
