Utilization of Triacetylcellulose Waste for the Production of Carbonaceous Adsorbents

Abstract

Triacetylcellulose(TAC)-based globular activated carbons having the adsorption capacity comparable with commercial ones have been derived using a carbonization system developed for this purpose. The carbonization of TAC proceeds through a liquid phase causing bubbling due to the emission of the decomposition gases. The phosphorus compounds resulting from the starting material of TAC waste promote the activation reactions to produce micro-pores.

“…However, such carbon resources are not sustainable because of their limited reserves and the rising price of oil. Instead of fossil fuels, several alternative starting materials have been proposed, such as coffee lees [1], triacetylcellulose waste [2], and oak woods [3], to produce AC.…”

Activated carbon production by co-carbonization of feathers using water-soluble phenolic resin under controlled graphitization

“…However, such carbon resources are not sustainable because of their limited reserves and the rising price of oil. Instead of fossil fuels, we have proposed alternative starting materials, such as coffee lees [1], triacetylcellulose waste [2], and oak woods [3], to produce AC. As for the cost of the resources, bottom ash [4] and waste rubber tires [5] are attractive, and adsorbents applicable to the wastewater treatments have been developed.…”
