Alternative Binder for Carbon Anode

Coal tar pitchCoal tar pitch (CTP) is traditionally used as binder material for the manufacturing of carbon anodeCarbon anode. Worldwide, researchers are exploring alternate materials of CTP due to its limited availability as well as high polycyclic aromatic hydrocarbons (PAHs) content. Key requirements from a binder material for making a good quality anodeAnode are coking value (CV), quinoline insoluble (QI) content, viscosity, and wettabilityWettability. In this study, petroleum pitchPetroleum pitch (PP) is blended with CTP in different proportions for making lab-scaleLab scale anodesAnode. Results showed adequate anodeAnode properties till 20% blending of petroleum pitchPetroleum pitch. Further increase in blending ratio deteriorates the anodeAnode properties such as baked anodeAnode density and compressive strength due to low CV and QI content of petroleum pitchPetroleum pitch. To improve the QI content in samples with higher proportions of petroleum pitchPetroleum pitch, appropriate additives were added. The result of this analysis is also discussed in this paper.
