A More Ecofriendly Cold Ramming Paste for an Aluminum Electrolysis Cell with Phenol–Formaldehyde Resin As Binder

Abstract: A cold ramming paste for aluminum electrolysis cells was synthesized with electro-calcined anthracite and artificial graphite as aggregate and phenol−formaldehyde resin as binder. The synthesized pastes were characterized by thermogravimetry, infrared spectroscopy, scanning electron microscopy−energy dispersive spectroscopy, and gas chromatography−mass spectrum. The results show that the synthesized cold ramming paste is an ecofriendly material and it has some superior physical properties, such as low electric… Show more

“…Lignin and collagen, in their raw form, are not construed as PAHs. Due to the restrictive legislation concerning the use of PAHs and the emission of these pollutants, and the sharp decline in coal tar supply, several attempts have aimed at finding a suitable substitute for these pitches, including pitch blends [4], organic resins [5], bio-oil residue [6], etc. Also there is great interest in developing novel uses for biomass and its derivatives that can offer sustainable alternatives to mined petroleum-based materials.…”

“…Specifically, collagen maintained its structural integrity through hydrogen bonds at ambient temperature, while the lignin-collagen hybrid system underwent a series of fusing reactions in-situ that even imparted the strength that kept the bricks in-tact up to 1400 ℃ in the heat zone of a full scale cupola [26,27]. Based on these favorable results with core binders and bindered anthracite bricks, the authors herein next set out 5 to explore whether these benign biomaterial-based binders from lignin and collagen could replace petrochemical pitches for the fabrication of graphite electrodes.…”
