Valorisation of polyolefins into magnetic carbon nanotubes: application as catalysts in wet peroxide oxidation of paracetamol

Sanches L., (Corresponding) dos Santos Silva A., Fontana Roman F., Diaz de Tuesta Triviño J., Alves da Silva F., Gomes H.

Topic:

Advanced oxidation processes

This work deals with the application of magnetic carbon nanotubes (MCNTs) in the catalytic wet peroxide oxidation (CWPO) of paracetamol (PCM), a pharmaceutical compound selected as model contaminant of emerging concern (CEC). MCNTs were synthetized by catalytic chemical vapor deposition (CCVD) at...Read more

Transferring the Carbonation of Biomass Bottom Ash from Batch to Continuous Operation

(Corresponding) Schnabel K., Brück F., Pohl S., Weigand H.

Topic:

Mineral carbonation of alkaline waste materials

Biomass incineration residues may be used for CO2 capture and storage by carbonation of waste-borne metal hydroxides. Moist carbonation of these ashes can be performed under mild conditions (ambient pressure and temperature) and accelerated by using a CO2-rich gas. The process requires the wetting...Read more

Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol

(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.

Topic:

Advanced oxidation processes

Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...Read more
