The continuous depolymerization of filled polytetrafluoroethylene with a continuous process

Van der Walt, I.J.; Bruinsma, O.S.L.; Grunenburg, A.T.; Nel, J.T.; Maluleke, G.G. (Wiley, 2008)

A new method for beneficiating unfilled as well as filled polytetrafluoroethylene (PTFE) waste has been developed. This process does not use any carrier gas while forming the depolymerization products. It enables polymer ...
Solvent extraction of a South African bituminous coal using a model biomass-derived phenolic mixture

Sehume, Thabo Z.; Strydom, Christien A.; Bunt, John R.; Schobert, Harold H. (SACI, 2019)

A model biomass-derived phenolic mixture was investigated for its solvent ability for extraction of a South African bituminous coal at temperatures of 300–360 °C. A previous study showed that phenol gave the highest ...
