Abstract Orange peels (OPs) were valorized in a lab-scale biorefinery loop for the recovery of limonene and subsequent production volatile fatty acids (VFAs) activated carbon (AC). Solid/liquid extraction was optimized using n -hexane at 85 °C with an OPs-to-solvent ratio 2:1, allowing yield 1.20% w/w. Then, post-extraction OPs used both VFAs AC. For VFA production, hydraulic retention time (HR...

Activated carbon has many applications in the environment, cosmetology, medicine and industry. The surface of each activated can be modified to obtain desired adsorption properties. Chemical activation greatly affect efficiency, control activity application carbon. aim study was modify selected by chemical physical methods, while maintaining these parameters so that it could used medicine. Powd...

The current study proposes a novel and improved cigarette filtration design comprising cellulose nanofibers (CNFs) powdered activated carbons (PACs) with different dry matter contents. proposed filter samples were primarily analyzed to verify their applicability as filters via measurements standard tests, such SEM, BET, DSC, airflow permeability analysis. results compared the acetate (CA) sampl...

Heteroatom-doped porous carbon has attracted considerable research interest due to its effective catalytic activity towards the oxygen reduction reaction (ORR). In this study, nitrogen-doped porous activated carbon (PAC) is fabricated via a facile heat-treatment and chemical activation of cocoon silk in an inert gas atmosphere. The prepared PAC exhibits excellent ORR catalytic performances with...

The potential of activated carbons--powdered (PAC) and granular (GAC), for the adsorption of acrylonitrile (AN) at different initial AN concentrations (50<or=C(0)<or=500 mg/l) from aqueous solutions was studied over the temperature range of 303-333 K. The effect of adsorbent dosage, initial AN concentration, contact time, and the change in pH with addition of adsorbents on adsorption was studie...

Abstract This paper discusses the preparation of modified activated carbon (PAC-1) and its adsorption performance for nitrosodiethylamine (NDEA). The PAC-1 was characterized by SMS X-ray diffractometer, NDEA removal mechanism investigated. results showed that, compared with unmodified carbon, had a better effect after pre-soaking 0.8 mol/L permanganate (PM) 24 hours calcination at 400 °C 7 hour...
